A cold experience, and not in the intended way.

Pros:
* Sufficient scenery and supplies in most areas.
* Scripted dialogue.
* Semi-unique finale style.
* Branching paths.

Cons:
* Names in the loading screen are in the wrong order.
* UI hints are lacking. Some events can come out of nowhere as a result.
* Some inaccessible areas for bots, mostly regarding some ammo piles.
Map 1:
* Coach's scripted dialogue is bugged.
* Bots don't leave the starting safe house until going considerably further from the room.
* Shelf in room has no collision.
Map 3:
* Starting from Map 3 has only the crappy Hunting Rifle.
* Scripted Tank spawns can be outright unfair in difficulty. Consider toning them down.
* Tank run at the end gives little to no chance for escape. Bots are basically dead weight at this point. I would give the survivors a bigger head start to compensate. It doesn't help that there's a large ladder at the end, which are basically Bot killers.

This map has a unique premise and potential, but is bogged down by questionable design decisions.

Modesty in the Mediterranian

Pros:
* Supplies are (for the most part) distributed reasonably.
* Most areas are sufficiently detailed.
* There were a few times where I got lost, but eventually found my way.

Cons:
* Survivor name list is out of order.
* No intro music.
* Tier 2 weapons available in map 1. They should usually be put off until map 2 or 3 in a campaign that's 5 maps long.
* I wouldn't put a Hunting Rifle at the start of map 2. Bots cannot use sniper rifles to save their life, making this more of a hindrance (not to mention it's still too early for Tier 2 weapons).
* A lot of blatanty borrowed assets from Half-Life 2. The combine tech and the character ragdolls are a particular example.
* Saferoom music at the start of Map 5 doesn't play.
* Music for the tank in the middle of the finale doesn't play. Music in general stops at this point.

A surprising update

Pros:
-Scripted Survivor Dialogue.
-Non linear design, yet not overly confusing.
-AI Nav is functional.
-Supplies are plentiful enough to get by.
-Bots are able to slide down the precarious slope in Map 3.
-Environment detailed and unique.
-Scavenge Finale.
-Hints placed at required points, and arrows guide the way forward.


Cons:
-The abundant Scoped rifle spawns can be a detriment for bots (this can be averted with the Left 4 Bots mod).
-Witch behavior sometimes doesn't match time of day in map 4 (though it may be more for the sake of gameplay than consistency).
-Grenades and Secondary Weapons are overly abundant.
-Witches appeared in the finale. Needless to say there's a reason why they don't appear in finales.


A lot of progress has been made since the previous iteration of this campaign. Biggest issue I have at the moment is the abundance of scoped rifle spawns throughout the campaign. As someone who plays with bots this is more of a bad thing (thankfully with the Left 4 Bots mod you can avoid the headaches associated with bots and sniper rifles).

No red scare in the red tide

Pros:
* Maps are detailed and functional.
* Lighting and arrows guide the way forward.
* Scripted dialogue.
* Helpful UI hints.
* A unique finale with a big, but not unfair challenge.

Cons:
* There's no melee weapon list. If this is empty, the game will use all melee weapons in random melee weapon spawns.
* Could use an ammo pile during the mid-section stop of the finale, as well as grenades.

An average campaign with a finale that stands out, but little else.

White Forest, with a lot of zombies

Pros:
* The first few chapters of Half-Life: Episode 2 converted into a Left 4 Dead 2 campaign.
* Supply placement adequate, although it gets a bit scarce in the thirdd map.
* Scripted survivor dialogue.
* Custom tank models.

Cons:
* Crude poster, names are out of order.
* Not enough 9mm pistol spawns at the start of the campaign, given the extra distance you need to travel to get the primary weapons.
* Ammo provisions scarce in Map 3.
* Event at the start of Map 3 made too difficult with the twin tanks, which should be reserved for finales only. I know this is to emulate the dueling Antlion Guard fight in HL2: EP2, but this would be better executed if they spawned in separately.
* Special Infected spawn rate needlessly increased at the end of Map 2, and possibly at the finale.
* Needlessly difficult finale; generators take a long time to activate given that there are many of them. Finale sequence should start upon hitting the switch, not after the generators are activated. There should only be one tank attack given the difficulty of activating the generators, never mind that the second wave has two tanks again. The abundance of explosive ammo does little to offset this.

It's a competent conversion of HL2: EP2's first few chapters, though difficult. I'd say City 17 does its job better.

Works as advertised

Until now I simply stuck with a simple cvar mod to improve the bots as I always wanted to go through the game at my own pace. This mod gives you many options, including if the bots are to go at their own pace or at yours, in addition to everything else mentioned.

Lengthy, reasonably challenging, but comes with a few flaws

Pros:
* Custom melee weapon (the Sledgehammer)
* Detailed environments
* Unique event in Map 3
* Custom intro and safehouse music
* Sufficient supplies


Cons:
* Hunting Rifle at the start of Map 2. This is a common mapper's mistake letting it spawn early in the campaign as bots are inclined to grab it, and bots are hopeless with sniper rifles. Map 2 felt like there were a LOT of sniper rifles in it in general when I went through it the first time.
* Easy to get lost in the warehouse in Map 3.
* Custom safehouse music loops awkwardly.
* Scripted dialogue does not come from the survivors, instead coming from the UI. This prevents subtitles from appearing. You need to use the entity "logic_choreographed_scene" in order to use survivor dialogue properly.
* Interactive objects continue to glow after they've been used (examples include the various buttons that start crescendo events).

This is the first new campaign that I've tried in a long time, and since the Last Stand update. It's a solid campaign that could use some improvements.

Pros:

-Adds three teammates just like in the previous game.
-Makes single player much more playable.

Cons:

-Peers may complain that this is cheating; ignore those pleas.

Conclusion:

An absolute must-have for people who have difficulty gathering friends.

Pros:

-Reload and firing animations deliver as promised.
-Includes moving animation, something the default set lacked.

Cons:

-There doesn't seem to be any bugs, missing features, or concerns.

Conclusion:

Recommended for observant players who use pistols.

Pros:

-Forking paths provided in each map.
-Rescue Closets uniquely implemented.
-Hints and clues are provided when needed.
-Supplies are sufficiently placed throughout.
-Environments detailed and sometimes unique.
-Available for Left 4 Dead 1.
-Navigation thoroughly checked and validated.
-Scripted Survivor Dialogue.

Cons:

-No introduction/safe room music.
-Endless Crescendos are only stated as Endless through graffiti, which can be easily missed in certain cases. Some may assume these are stationary, only to find out they're battling wave after wave.
-Boss Infected appear to be very common in Maps 6 and 7.
-Certain textures are invisible if Precinct 84 is enabled.
-Adjusting with the addons will render some models unusable. Should this happen, restart your game and don't touch the addons until you play this.

Conclusion:

Another welcome entry for Left 4 Dead 1's Campaign library. The length of this adventure rivals that of Vienna Calling, with eight Maps (which isn't necessarily a good thing). Gameplay is balanced, but it keeps players on their toes. There's a few balance and technical problems, but nothing overwhelming.

Pros:

-AI and navigation is completely functional.
-Supplies spread throughout evenly.
-Gameplay is mostly balanced.
-Environment is detailed.
-Custom Finale.
-Scavenger Hunt is a provided self-imposed challenge.

Cons:

-Bots have difficulty going down the ladder leading to the parking lot in the beginning of Map 2.
-The Witch house in Map 2 can be very fatal on higher difficulties, despite being mostly remedied by a Shotgun provided beforehand.
-Some scripted Special Infected can take the Survivors off-guard.

Conclusion:

A Campaign that makes itself stand out with custom scripting, yet sticks to a balanced formula.

Pros:

-Health supplies plentiful.
-Ammo piles placed properly.
-Scripted Survivor dialogue.
-Hints are provided when needed, and arrows point to the way forward in forks and paths.
-Custom dialogue.
-Custom intro and outro music.
-Environments detailed.

Cons:

-No music plays  in the Safe Rooms.
-Safe Rooms are often provided with an AK-47 and a Combat Shotgun, and no other weapons.
-Additional music in Map 2 is unnecessary.
-Bots sometimes get stuck in certain places. One of them fell to his death in Map 3's lethal lake.
-Witch garden in Map 4 can be troublesome due to close-quarters placements.
-Bots have massive difficulty getting up floors in the Finale arena.
-Two Tanks appear on each Tank wave in the Finale. This is highly discouraged.
-There should be a way to access the marathon on the ground level; it looks like the gate there would open up. As of right now, the only way to get there is via the bridge.
-Could use a Bile Bomb in the middle of the Finale's run to the Helicopter.
-Or simply shorten the distance of the run.

Conclusion:

Another scenario based around a real landmark, which in some ways, provides an atmosphere for good gameplay. Weapon diversity is limited to mostly AK-47 Rifles and sometimes Combat Shotguns in most of the maps however, and some areas have unbalanced (the Witch maze in Map 4 comes to mind). Nonetheless, the Campaign can be conquered alone, which makes this content qualify as a good Project.

Priorities for the author include expanding said weapon diversity, as well as providing a few tools to counteract any unfortunate incidents involving the game-breaking regions. The Finale provides more supplies than normal due to the additional Tanks on each wave, as well as the marathon to the Helicopter's LZ, although even then, the Finale's still quite difficult due to the many areas the Infected can attack from.

Pros:

-Very entertaining, and lengthy for a 4-map campaign.
-No major bot issues (some, but only due to SI and hordes overwhelming them as usual).
-Scripted dialogue.
-Well-placed crescendo events.
-Nice optional event in the second map.
-Original idea: Turning on the signal lights after the usual waves in finale.
-No major ammo issues (except at finale).
-Decent amount of supplies.
-Very atmospheric.
-Various Uncommon Infected types.

Cons:

-Poster could use a tagline.
-Some Hunting Rifles in the Campaign spawn during Mutations such as Gib Fest.
-Bots kind of get lost in finale at times.
-No Ammo Dumps at the finale.

Conclusion:

A thoroughly functional Campaign with an urban environment. What makes this stand out are the optional events and objectives for the Survivors to perform if they wish to get in on bonuses.

Pros:

-Uncommon Infected (Fallen Survivors and Hazmat Infected).
-No supply issues. Health and Ammo is scattered evenly throughout.
-Bots aren't too shabby. They do tend to fall down ladders and tall points at times though.
-Notices warn players along the way.

Cons:

-Lack of scripted Survivor dialogue.
-Names for Survivors in poster are out of place.
-Could use a few breaks in the train track crescendo.
-The area where Gordon apparently gets "lost" is not featured in the Campaign; it can be found as a Survival Map.
-Survivors can get stuck near the concrete platform in Map 3's graveyard.
-Bots cannot access items in the mine shed in Map 3.
-Even though the Finale is nice and wide, there's never an excuse to have two Tanks appear at once.

Conclusion:

A welcome adaptation of Half-Life 2's horror show. Though Ravenholm is free of Grigori's signature traps, the layout of the town is more than suitable for a zombie outbreak, and this work vouches for that claim. Trivial features, such as Survivor dialogue, are absent here, so far.

Pros:

-Nice intro sequence, with original music and sounds.
-Environment thoroughly detailed.
-Customized doors (though bots may have trouble getting through them).
-Custom dialogue
-Easy to navigate, yet non-linear in areas.
-Author was genre-savvy enough to prevent Bots from grabbing a Hunting Rifle in Map 2, allowing players to use them instead (if they aren't Zoey).
-Crescendo Events have nice touches and original functionality.
-Bot navigation is planned out accordingly.
-Supplies are more or less spread out evenly, and gameplay balance meets the par.
-Available for L4D1.

Cons:

-Lack of instructor notes for Crescendo Events. Use pre-existing ones or overlays as a start.
-Lack of scripted Survivor dialogue in most areas.
-Customized doors are indestructible; this can be exploited heavily.
-Door models are used for unusuable doors; use overlays instead.
-Health Kits at the side room beyond the Safe Room in Map 1 is  unnecessary.
-Could use Ammo or spare Weapons next to Map 2's Event.
-Map 2 doesn't have many medical supplies.
-During Map 3's Event, the Survivors won't stop talking until they reach the end of the sewers, and their dialogue tends to overlap.
-It's easy to get lost in the Finale; try making the radio glow upon entry to the arena, or add arrows.

Conclusion:

A detailed Campaign ideal for a quick run-through. Some parts of the Campaign are a bit less generous on supplies than others, but are otherwise balanced out thorougly. The idea of supplies hidden within many of the lockers encourages exploration and curiousity.

Pros:

-Supernatural phenomena are (mostly) well executed and easy to notice.
-Despite the supernatural disasters, rifts, and obstacles that occur on the grid, they aren't too harmful or game-breaking, even to Bots.
-Navigation is marked functionally and without much fuss (before the Finale).
-Ammo is spread throughout sufficiently.
-The pathway isn't too hard to figure out, and arrows are added for good measure.
-The Crescendo Event points out where the end of said event is located.
-Many custom textures and models are provided.

Cons:

-Official music intro overlaps the custom one.
-Survivors can't hold onto ledges over the rift.
-Hardly any Secondary Weapons before the Finale.
-Supplies (save for Ammo) are a bit scarce.
-Bots do not use the Ammo Cache or pick up the Weapons on the table in the Finale.
-Bots have trouble getting into the helicopter at the end of the Finale.

Conclusion:

A short, but functional journey through what seems to be an ordinary town. As the contest requires, many supernatural disasters occur through the adventure. Though the latest update has provided a proper intro, a bit of scripted dialogue, and custom soundtracks, the necessities of gameplay standards fall short, as there are a few navigation problems, some game breakers, and not many supplies.

Pros:

-Bot navigation is within playable quality.
-Custom Dialogue, given by the mission control.
-Instructions provided via floating overlays.
-Sufficient supplies; all standard requirements met when it comes to Ammo, Grenades, and Medical Items.
-A balanced Finale that combines the mechanics of stationary and mobile Finales.
-Environment has believable detail.
-Has quite a few custom textures.

Cons:

-Supplies are a bit too dense. The armory in particular houses a game-breaking amount of supplies.
-Instructions given through unproffessional means (usually, they're given via the game instructor. In L4D2, it's possible to create custom messages through it).
-Typos can be spotted within these instruction messages.
-Open environments are less detailed than indoor ones.
-There's no main music theme. Incoing Hordes are harder to detect.
-Radio Audio comes out of visibly nowhere. I assume the Survivors are carrying their own radios.
-Radio Audio may be hard to hear in midst of fight. Perhaps an option to repeat the audio through radios planted on the ground may help.
-Weapon availability focuses nearly soley on Assault Rifles. I understand the reason for excluding Scoped Rifles, but Auto Shotguns too?
-No Health Kits provided at the start; this is compensated by Health Kits being provided later on in the level.
-Special Infected can get stuck behind the closed metal blast doors, and have no other means of getting past them.
-Infected can attack through floor in Map 3's Dam before it gets blown to bits.
-Smokers can pull people to their death in Map 3 (on the catwalk over the river leading to waterfall, outdoors). They can't even cling at the edge of said catwalk!
-The overuse of ladders at the end of the Finale may get Bots stuck, much like how they can get stuck at the top or bottom in many scenarios.

Conclusion:

This adventure isn't a mere A to B trek; there are certain objectives that must be accomplished in order to break the local Dam that holds the water flow that will kill the Infected. An easy, though still entertaining Campaign. Thoroughly superior to Dam It! in every category. Weapon variety is niche though, and there are some game-breaking elements present.

Pros:

-Has scripted Survivor Dialogue.
-Alters the Zombie population; Formal, Construction, Hazmat, and Riot Infected (the usual cabal) appear periodically.
-Has a mostly non-linear layout. Arrows guide the way forward through these numerous paths.
-Intricate detail throughout each map.
-There are some helpful notices in certain areas. One area that comes to mind is the fumigated room in Map 3.

Cons:

-No intro music.
-Bat AI navigation; Bots can get trapped behind obstacles, must resort to teleporting frequently, and can fall off rooftops, hurting themselves.
-Boss Infected appear in Map 1 without Primary Weapons. Survivors WILL get hurt early on in the Campaign.
-Supplies are extremely scarce. Ammo and Health Kits in particular need to be added.
-Notices for Crescendo Events don't appear until it's too late. Gauntlet Crescendos don't point out the end switch.
-Slow Motion explosion in Map 2 unnecessary.
-Unobtainable Pills has been spotted in footlocker in Map 3.
-Maps are excruciatingly long.

Conclusion:

Urban Disaster lives up to its name (emphasis on "Disaster"). One of the most frequently-made mistakes made by many mapmakers is forgetting to focus on gameplay, and instead focus on the optional eye-candy. This map is a prime example. Game balance is thrown out the window, and most players will not be able to complete the Campaign in a happy mood due to the hostile nature of the level design and the scarcity of supplies, weapons, and the dense pockets of Infected. Don't judge a book by its cover; even if it's pretty, it can taste sore on the inside.

Pros:

-Lots of custom content.
-Detailed environment.
-Scripted dialogue.
-Weapons, Ammo, and Grenades are spread out evenly.
-Stays true to the source material.
-Uses a Gauntlet Crescendo; the lack of Melee Weapons is made up with extra supplies and the infinite-shove technique.
-Makes use of the Biohazard Tank model.
-Available for L4D1.

Cons:

-Could use written instructions (ie, Game Instructor messages. I know it's not possible to create custom text for these, but try other methods!) for Events, traps, and mazes. Notable examples include the electrified flood and the plank-over-the-gap.
-Health supplies are scarce; the majority of the Pills found throughout the Campaign are located in the Health Stations, but the overwhelming amount of zombies forces the Survivors to demand more.
-Map 2's crows event is kind of ad-libbed and random.
-Bots fell to their death when I backtracked through the roof.
-I've encountered two Tanks in short succession in Map 4. Is the one at the helipad a scripted spawn?
-Serious navigation issues in Map 4's ladder near the end of the map; Bots got stuck, preventing themselves from moving forward.
-Ladder in Map 5 leading downward is far too high; Bots may fall and hurt themselves badly.
-Boss Infected in Map 5 are unnecessary.
-It was a bit hard to find out what would trigger the Finale. A Game Instructor message would work wonders here if we could make our own.
-It's not complete. Yet. Starting from the second map is a bit jarring.

Conclusion:

A very detailed Campaign, but very frustrating to get through due to the flaws pointed out in this review. The content in this adventure is still promising, and if there's anything that will bring L4D1 back on its feet, this one will make a significant contribution. Focus on optimizing the game experience and balance throughout the levels, and try to ease up the difficulty; it took me multiple tries to get through each level with enough supplies in hand, as well as creating the introduction.

Pros:

-Increased dialogue scripts and variables.
-Many dialogue scripts from L4D1 were removed in the transition to L4D2; this mod brings most of them back.

Other additions include:
-Coach and Rochelle being able to comment on Car Alarms.
-Tank death responses.
-Survivors refer Magnums as Pistols (before they used more generic quotes).
-"Argh!" command is expanded.
-The elevator script during The Passing's Finale now allows other Survivors to make comments, instead of just Coach.

Cons:

-Like most other mods, it doesn't work on Official Dedicated Servers.
-Healing Thank responses occur a bit too early for L4D2 Survivors (their Heal responsees are often too long, and get cut off).
-Survivors may address Special Infected by their Dead Center nicknames in maps outside the first half of Dead Center and vice-versa.
-Healing lines should stay as they were (Adrenaline, post-Healing, and Pain Pill responses shouldn't be mixed together, and early Dead Center Healing lines should remain there too).
-Survivors still refer 9mm Pistols as generic Weapons, instead of using their Pistol-specific lines like they now do with Magnum Pistols.
-"Argh!" command is disabled upon repeated use.

Conclusion:

One of the more practical mods out there. This is the most expansive dialogue expansion I've downloaded yet. Ideal for the lonely player. There's still a few loose ends that could be wrapped up though (most of them can be taken care of through manual configuration).

Pros:

-Offers all the Official Mutations, as well as some pre-made ones to be played at any time.
-Versus Coop is a notable addition; now you don't have to deal with the ragequitting if you want to play as the Infected!

Cons:

-Versus Coop rounds often start with the Survivor Bots rushing, even though the player hasn't loaded yet (on their team).
-Custom Mutations will become incompatible with other mods that modify the gamemodes.txt file.
-Single Player Mutations must be accessed through lobbies; Official Solo Mutations cannot be paused.

Conclusion:

There's no reason to refuse this mod. It offers a variety of different setups, and multiplayer is still functional. The only drawback is the incompatibility with certain mods. This is a priority fix.

Pros:

-Scripted Survivor Dialogue.
-No supply issues.
-Amazing environment.
-Campaign instructions in the van.
-Plenty of detail.
-Large and flexible finale.
-Nice airboat plane!

Cons:

-Bots can get lost in the Manor.
-Rolling Crescendo event doesn't work all that well in L4D; try giving the Survivors a few breaks in between when they try to run to the helipad.
-Finale Minigun needs a bit more flexibility.
-I thought I only saw 3 Health Kits in the last level's safe room.
-A little easy to get lost.
-A bit too dark.
-Francis' comment at the intro. Rather keep those lines within the rare run through Crash Course, or out of the game entirely.

Conclusion:

A massive Campaign that came to critical acclaim. Most cons are personal issues, or the odd gameplay balance fix.

Pros:

-Minecraft textures and models for everything save the Survivor and Infected models.
-Various changes in level pathing for multiple playthroughs.
-Conventional level elements are complemented by Minecraft elements (gathering materials and chests, for example).
-Lots of outside shout outs.
-Gameplay and supplies are not hindered by customized elements.
-Plenty of scripted Survivor dialogue.
-Instructions given out through signs.
-Easter egg corpses.
-Available for Left 4 Dead 1.

Cons:

-Somewhat easy to get stuck in tight places.
-Chests that contain items should glow, just in case.
-Bots should be blocked from the lava; Francis got himself incapacitated three times by lava alone!
-Francis' Canada comment at the start of Map 3. I'd rather keep it within the rare run of Crash Course.
-Item-hunting scenario in Map 4 can become time consuming without any guidance (perhaps when the Survivors reach the lava wall, the items they need will glow regardless of player location).
-Some areas in Finale are a bit too easy to defend.
-Entirety of the lighthouse is not accessible; looks like a fine place to fight!

Conclusion:

A fantastic campaign, even for those unaware of Minecraft! It's a fresh take on a familiar formula.

Pros:

-The Passing's soundtrack fits in with Rayford-influenced scenery.
-Crescendo Event in Map 3 unique.
-No urgent supply issues.
-Finale very intense.
-Bots are quite functional (most of the time).
-Smooth looking poster.

Cons:

-No Uncommon Infected, except around the quarantine tents in Map 1.
-Lack of Survivor dialogue other than in the intro.
-Navigation error in Map 2, inside the building under construction beyond the streets, bots may get trapped in the first-floor dressing room.
-Map 3's Floodgates should have additional Infected ladders from the water. They tend to be trapped between the bridges, or get stuck below.
-Lack of Pistols in Maps 3 and 4.
-Could use a Chainsaw in the Finale, as well as some (more) Consumables (Pills/Adrenaline) and Health Kits after the Tank sequence.
-Spelling error in the Finale helipad ("rascue").
-Bots can jump to the helicopter too early, falling to their deaths.

Conclusion:

A nice Campaign with satisfactory gameplay and playable balance. One hook this Campaign provides is a Sniper Rifle guaranteed to spawn in Map 2, ideal for those that don't play as Ellis.

Pros:

-No issues with supplies or AI.
-Great environment.
-Custom soundtrack.
-Great lighting.
-Ample amount of Defibrillators and Superweapons.
-No performance or gameplay issues (save for the nitpicky parts in the cons area of this review).
-Mutations such as Gib Fest work normally.

Cons:

-A bit too much daylight. Perhaps have the night take over in the later maps (or have a nice sunset)?
-Merely a port, perhaps change a bit of the gameplay during the events?
-Lack of Uncommon Infected.
-Lack of scripted Survivor dialogue.
-Bots don't grab anything from the start until reaching out to the stairs (make them act when reaching the boxes with the weapons on them).
-Game tends to crash when quitting the level from Map 1 at times.
-Tier 2 Weapons spawn too soon (they can be found in a room in Map 1).
-Could use a text notice for Map 2's gate regarding the power.
-Bots don't go through the gate in Map 3 (the optional one, that goes from the Alarm Car to the garage).
-Corpses disappear upon hitting the floor in Map 4; this is explained because of the water effects.
-Secure a few of the ledges; there's too many Death-Charger locations!
-Having two Tanks during the second Tank wave unwelcome in the acrophobic Finale environment.
-Provide more than one way up to the lighthouse. Lower some of the positions so that being punched by a Tank isn't an instant-kill.
-Need more Pills and Adrenaline in the Finale.
-Getaway music is a bit too quiet.

Conclusion:

A welcome return of an old classic (Death Aboard was my first Campaign I've downloaded from here, I don't regret it). Only a few things to sort out as noted, most notably in the Finale.

Pros:

-AI usually works like normal. Survivor Bots make it over the gap of death.
-Custom textures and environments.
-Keeps the L4D2 Survivors.
-Supplies sufficient.
-Non-linear, but hard to get lost (mostly).
-Scripted dialogue.
-Custom music.
-Original ideas in Map 2 (use the lanterns to enter the palace, Sacrifice style).

Cons:

-Some areas are a bit bland.
-Texturing could be improved (notably in the Finale).
-Fix the grammar in the poster.
-Doesn't look apocalyptic.
-No Witches.
-Could use some arrows for extra guidance.
-A few weapon spawns appear in Mutations such as Gib Fest, when they shouldn't (examples include a weapon or two in Map 1, the Chrome Shotgun at the end of Map 1's trailer Safe Room, and the Sniper Rifle at the palace).
-Grenades are a bit excessive in Map 1.
-Certain item placements are a bit predictable and fixed.
-A few texture issues (one noticeable one being the planks barring the palace door in Map 2 partially disappearing).
-Skybox tends to mess up in the beginning of Map 2 on lower graphical settings.
-"Using" the lanterns in Map 2 to unlock the palace door doesn't make much sense. Perhaps include text instructions to specify the objective.
-Nav isn't covered in certain staircases in the buildings where the lanterns are.
-Finale's a bit Charger-deadly.
-Could use some weapons along with the Ammo Dumps in Finale (before encountering the Tank).
-Could use a few breaks in the hordes during the Finale.
-When the Finale spawns both Tanks and Hordes (in the usual ending fashion), make it wait until the Survivors are a bit closer to the Helicopter.
-Survivor Bots tend to head towards and go down the ladder next to the helicopter; block it for them.

Conclusion:

Another worthy candidate of The People's Republic Contest. Few performance or gameplay issues, most of them are cosmetic. Finale's a bit rough though. Improve upon these to get a higher score.

Pros:

-Environmental details and graphics are on par with the standard.
-Hazmat Infected (but only at one small part in the Campaign).
-No (or hardly any) game-breaking bugs or issues.
-Balanced gameplay throughout majority of Campaign.
-Clear instructions given at necessary points.
-Non-linear areas in addition to main pathways, features Valve's signature illusion of free pathfinding.
-Subversions of Finale formula that don't make the game too difficult or uninteresting.
-Carried Off Poster is hidden beneath loading screen in clever Valve fashion.

Cons:

-Forewarning for Map 2's event may disappear after a few seconds.
-Levels are a bit overly long.
-It may be me, but Boss spawns seem to be predictable.

Conclusion:

Another fun and worthy Campaign for the quick runners and those who seek twists and surprises.

Pros:

-Indicates how much Health each Survivor has through numerals and not just an ambiguous bar.
-Ideal for the team-player.
-Helps to sort out who to heal first.
-Bot healing can be predicted more easily (they will use drugs under 60 Health, and will Heal themselves under 40 Health).

Cons:

-Counter should say 0 or disappear upon death.

Conclusion:

A mod that actually serves a practical purpose. Currently, it is only available in Single-Player and in Local Servers.

Pros:

-Great environment, posters, and tagline.
-Lots of custom models.
-Bot navigation workable.
-Various Uncommon Infected.
-Supplies sufficient.
-Fun Finale. Has multiple camping plans.
-Arrows guide the way forward, making it easy to determine where the extra supplies are.
-Defibrillators, lots of Chainsaws.
-Machine Gun emplacements very handy. A good way to rack up kills!
-Fair length.
-Map 3's Barricade Event makes a twist on the Gauntlet formula (more Special Infected rather than constant hordes).
-Bots are capable of moving into the elevator in Map 4.
-Custom ending Soundtrack.

Cons:

-Two separate posters with two different Survivor positions. If only there was a way to adjust both of them separately...
-Perhaps add Infected-only ladders to the holes in Map 1 so that the Special Infected don't get stuck below.
-Bots should be able to get deeper in the Turret wall in Map 3 (they usually only stand on the ladder).
-Bots tend to rush onto the track at the end of the Finale when the train arrives. No sane person would do this in real life.

Conclusion:

A campaign with immense dedication to development and fantastic gameplay! Gameplay is balanced, and all cons are minor or extremely situational.

Pros:

-Scripted Survivor Dialogue.
-Custom Dialogue.
-Not merely a remake; a mix of old and new environments.
-Custom Soundtrack.
-Crescendo Events well-thought out.
-Various Uncommon Infected.
-Good Bot navigation.
-Sufficient Supplies.
-Lengthy.
-Supplies sufficient (mostly).
-Instructions for significant events.
-Custom Tank models at Finale.
-Superfan Melee Weapon.
-Easter Egg in Map 5. I won't give all of it away (even though it may be "It was his Sled" by now), but from my experience, the Bots are still quite functional in that region, even though they clearly aren't programmed for that.

Cons:

-Performance issues and long loading times on older computers.
-Bot Ellis got stuck on a ladder at the start of Map 5 once; we couldn't continue on.
-No regular Survivor Dialogue during Finale (scripted Dialogue still plays).

Conclusion:

A Campaign full of adaptation expansion and creativity. The only bad part about this Campaign is the amount of resources it needs to run on, as well as a few quirks in the Finale.

Pros:

-Nearly infinite supplies.
-Selection of Weapons allows "tweaking" of weapon stats.
-Buttons on the wall for customized events and songs.
-A way to end the map and save stats through the Saferoom.

Cons:

-Bots have trouble navigating in and out of the hidden Machine Gun room.
-Could use more Machine Guns due to how one overheats for a long time.
-Perhaps include a Minigun.
-Should have a way to turn off the incoming hordes if needed.
-Heading to the Safe Room should display the credits, instead of the between levels loading screen (for a more "conclusive" ending).

Conclusion:

Scientist Slaughterhouse meets Left 4 Dead. Want to kill more enemies with a certain weapon? Go ahead and head to the range!

Pros:

-Original (and pleasant) Soundtrack, all over the place (except for the horde alert theme).
-L4D2 Survivors, the way this game was meant to be played!
-Scripted Survivor dialogue.
-Innovative ideas that don't interfere with traditional gameplay.
-Arrows lead the way.
-Sufficient supplies.
-AI on par with norm.
-Instructions during irregular events.
-Original environments; the winter climate alone makes a nice change.
-Various Uncommon Infected.
-Flexible layout in Map 2; multiple paths converge and divert at appropriate times.
-Ice physics in Finale work believably.
-Fireworks don't detonate in their spawn places if someone shoots or blows them up by accident.

Cons:

-Short in overall length, but the transition from the plane to the ground serves as an easy gap for the author to place more maps if necessary.
-Bots rush to the exit in the Plane, even if less than four Parachutes are located (use a nav_blocker to block the door off until all Parachutes have been found).
-A grammar mistake in Map 1 ("You must found 4 parachute bags before exit the air liner" should be "You must find 4 parachutes before exiting the air liner").
-Bosses can spawn in Map 1; with the lack of primary weapons, this is a no-no.
-Somewhat easy to get lost in Map 2, even with the arrows!
-Safe Room Music should only end in Map 2 when the Survivors go through the gate. It's nice to listen to when gathering the supplies in the tent.
-Could trim down the amounts of Riot Infected in Map 2's Event.
-Bots tend to get stuck in the towers in Map 2 (especially near the ladders). One notable place is inside the tower, just before the Crescendo Event.
-Bots sometimes jump off the wall, hurting themselves.
-Bots also tend to get stuck at the ladder in the Finale.
-Theoretical: What if the Survivors run out of fireworks in the Finale?
-Could use an Ammo dump at the docks near the boat, or on the boat in the Finale (somewhere near the ice next to the boat).
-Could also use a Defibrillator, seeing as how it's easy to die due to falling.
-Perhaps ice physics could be downplayed, it's hard to accelerate on the ice (or compensate it with Laser Sights).
-Finale is bugged in Gib Fest; the "escape" sequence starts immediately, and the Tanks overrun the Survivors before they can use the Fireworks!
-Too many Tanks spawn in the process of the Finale (they spawn in timed intervals, but spawning them according to amount of ice melt would be better).
-Map 2 may crash with certain addons added; these MUST be REMOVED from the folder for it to work.

Conclusion:

Finally! A worthy candidate for the Chinese Contest! Not only does it include the essentials for the contest (and our beloved L4D2 Survivors), it also toys with original (yet functional) ideas and gameplay. The only downsides are its short length, several Bot issues and a difficult Finale with lots of game-breaking elements. This one's clearly the winner of the contest!

Pros:

-A couple of Mud Men here and there.
-Re-energizes the horror theme in Left 4 Dead.
-No big supply issues.
-A little bit of Survivor Dialogue.
-Graffiti used for humour and level tips.
-Outstanding environment.
-Scripted dialogue.
-Although located in the thick of the woods, it's not easy to get lost here. Lights help for navigation.
-Nice moon.
-Bot navigation not too troublesome.
-Multiple pathways in Map 1 and 2.
-Unique ways of initiating Crescendo Events (instructions are given through means other than text messages and initialized in ways not done before).

Cons:

-Ugly Gas Can and Propane Tank models.
-Could use traditional text messages before Crescendo Events and Finales to specify the goal.
-Dark Carnival soundtrack may be more suitable than The Passing's, or perhaps use The Sacrifice's.
-Weapon placements predictable.
-Melee Weapons placed on top of boxes (the physics types) will not drop when boxes are destroyed.
-Bots don't use the Ammo Dump in the house in Map 1 (maybe).
-There are two Ammo Dumps close to one another in Map 1 (in the tunnel with the Witch and Event in it).
-Gun spawn in Map 2 (in Church) may mess up gameplay in Mutations such as Gib Fest.
-Survivors can't cling on the gap ledges of the Finale.
-Could use a Pipe Bomb or Bile Bomb during the final escape sequence (when nearing the boat).
-Kind of fell off the boat in the finale when I ran too far; you should put up an invisible wall to prevent such things.

Conclusion:

Seeing as you're the co-author of Night Terror, I'm not surprised in how much this reminds me of said Campaign. Nice work, continue to focus your efforts on fixing the cons (all cons are now trivial and are not game-breaking). A keeper.

Pros:

-Scripted Survivor dialogue.
-Mostly good Bot navigation.
-Flares and green lights light the way forward, as well as arrows.
-Fascinating facility environment.
-Signs give out certain directions.

Cons:

-No intro or Safe Room music.
-Weapon and Item placements a bit predictable.
-Could have a light by the Surface door in Map 1.
-Boss Infected appear to be overly abundant in Map 2.
-Can't seem to find many Closets in Map 2 (the only ones I came across where the outhouses and the one in the lone house).
-Could use an Ammo Dump in Map 2 before the tower.
-Bots do not follow up into said tower, and they cannot collect the Weapons or Ammunition inside.
-Map 3's ladder is extremely lethal towards Bots. Break it into multiple parts if possible (expand the shaft, maybe?).
-Need more supplies in Map 4. There's hardly any Pills or Grenades in particular.
-Could use a delay in Map 4's Crescendo Event in order to reach the catwalks safely.
-Bot navigation a bit wonky in Finale; Bots sometimes get stuck near the truck and whatnot.
-Perhaps the Finale could use some additional Pills.

Conclusion:

A detailed, though tough campaign. Map 4, however, stands out as a sore thumb in an otherwise balanced gameplay experience.

Pros:

-Unique Comic Book feel through sound sources and Map interface graphics.
-Bots go from points A to B, and follow sufficiently.
-Supplies and difficulty balance each other out.
-Clear Instructions given at necessary points.
-Believable environment.
-Scripted Survivor Dialogue.
-Quick, numerous levels would be ideal for Versus Mode (I think).
-Various Uncommon Infected.
-Custom graffiti.
-A unique twist in the Finale (though it has a few gameplay issues).

Cons:

-Survivor names in Poster are out of place (looking carefully at the comic pretty much determines where they are).
-Bots do not grab the supplies in Map 5's Safe Room, nor do they collect the Ammo at the Finale.
-Bile Bombs in Map 5's Event are a bit excessive.
-Need four Health Kits and some Weapons at the Finale arena.
-Dash to the rescue vehicle can end horribly so easily (Tanks and Chargers can ruin everything so quickly).

Conclusion:

A smashing Campaign with loads of destruction and mayhem. There's a few Bot issues regarding supply management (remember to cover the tops of the tables and crates with the supplies when manually creating nav meshes!), though the Campaign's status here is still manageable.

Pros:

-Supplies sufficient.
-Working AI navigation.
-Non-linear to the right extent.
-Custom sounds and music intro.
-Nice pools.
-Instructions provided for interactive objects (though unclear at times, whether or not they summon Hordes).

Cons:

-Loading Screen displays the wrong Survivors (the ones playable here are different from the ones shown in the Poster).
-No regular Music (ie, no Safe Room music, no Horde warnings. Other tracks work normally).
-No scripted Dialogue.
-Skybox messes up at times.
-There are a few Grenade and Melee Weapon spawns that have more than one item in each (this, of course, shouldn't be).
-Objects that are meant to spawn hordes don't display the "Here they come!" scripts (panic event scripts).
-Objects that glow don't stop glowing once used.
-Map 2 could easily be split into two parts; it is too long as it is.
-Map 2's Gauntlet Event does not indicate that the Survivors must cut through, let alone where to find the switch that ends it (increase the glow radius of said switch).
-Building in Map 2 could use more arrows and guidance, I got lost in there a few times.
-Bots get stuck near a corner next to the rails in the Finale.

Conclusion:

An ordinary Campaign. Some areas in particular are tedious, but they aren't excruciating. A bit of balance fixes here and there will certainly improve the score (as well as some other corrections).

Pros:

-Flowed well, not too many bot issues.
-Custom dialogue, as well as in-game and scripted dialogue.
-Nice scenery.
-Hard to get lost.
-Instructions provided.
-Sufficient amount of weapons and supplies.
-A few nice easter eggs.
-Explosive Barrels.

Cons:

-Finale is wide open.
-Could use a few grenades in Finale.
-Could program the bots to get on the train better. Make it so that the Survivors must talk to the radio again to get the train moving so that it doesn't leave anyone behind.

Conclusion:

A detailed, thorough campaign. Only trouble was at the train and at the Finale.

Pros:

-Custom textures.
-Custom soundtrack at intro.
-Scripted dialogue.
-Modified text on items and environment.

Cons:

-No supplies in Safe Rooms (upon reaching them between levels that is, starting in the levels themselves, the supplies are there).
-No special gameplay mechanics.
-Doesn't feel too Chinese outside the text and Map 1.
-Finale cramped and unimaginative.
-Bots get stuck at parts.
-No logic to why the train suddenly moves in Map 3.
-A Tank spawned at the end of the train ride in Map 3.
-Helicopter at finale takes too long to arrive (even by most standards).
-Stats don't appear in the credits.
-L4D1 Survivors in a L4D2 exclusive, a real knife in the heart to those who play the original game.

Conclusion:

A cash-in to the contest that fails to deliver a memorable experience. Quite overrated. Not everyone enjoys this campaign, get over it.

Pros:

-Authentic environment.
-Nice poster.
-Massive length.
-Multiple paths in areas.
-AI good for such complex layouts.
-Arrows guide the way.
-Custom Propane Tank models.
-Custom Common Infected models.
-Various Uncommon Infected.
-Supplies sufficient.
-Scripted dialogue.

Cons:

-Survivor names in poster are out of place.
-Bots don't move at start of map (climb the scaffoldings to get them started).
-Could use some more closets in certain spots.
-During Crescendo Events, the "Horde Incoming" track overlaps itself repeatedly; this may be due to the amount of hordes being constantly spawned during them, so tone it down!
-Bots sometimes don't follow or get stuck (at various points).
-Bots will not go on the elevator on their own; they may require pushing or teleporting).
-Scoped Rifle in Map 1 should be a single spawn, or nonexistant.
-Somewhat easy to get lost.
-Could use an Ammo Dump where the first Safe Room's supplies are.
-Falling car in Map 2 (before Crescendo) could drop in the chasm rather than on the path to prevent any accidents.
-Lack of Pistols in Map 2.
-Starting room in Map 3 could use a Tier 2 Weapon.
-Plane Crescendo in Map 3 did not tell me to get across to the howitzer to stop the alarm.
-Could use some more Bile Bombs in the Finale path.
-If you intend to have Hordes attack during the Tank Battle, include a Bile Bomb, or perhaps remove some of the junk that the Tank can toss for instant incapacitation!
-Finale music (the one that usually has the text "Rescue is on its way") should start when reaching the surface in the elevator, not when opening the gate just before the rush to the helicopter.

Conclusion:

A Campaign that focuses on eye-candy rather than gameplay (though it doesn't fail in that aspect either). There's a few quirks with this, though they can be easy to fix. Ideal for those looking for a challenge.

Pros:

-No gameplay issues for the most part.
-No supply issues.
-Moderate difficulty.
-Believable environment.
-Interesting finale.
-AI usually functional.

Cons:

-I can still hear sounds when the credits roll.
-Second Tier Weapons available too early (they can be found in a hidden room in Map 1!).
-No scripted dialogue.
-Supplies do not appear in Safe Houses until the next level is loaded (minor, but still notable).
-Second Map's Crescendo Event needs a notice to turn on the power in order to get through the gate.
-Bots may fall down the manholes in Map 2, injuring themselves.
-A Bot may get stuck at the gate in Map 3.
-Finale may be a little too big; Tanks can punch the Survivors off the cliffs easily!
-Is it me, or do Bots tend to teleport off the cliff to their death during the Finale at times?

Conclusion:

The first Campaign I've downloaded for L4D, and one of the worthiest entries of all time. Please don't pull the plug on this campaign, and continue to debug it!

Pros:

-Survivor dialogue.
-Safe Room and Intro music.
-Wide environment.
-Bot navigation satisfactory.
-Explosive Barrels.
-Custom Ammo Dump models.
-Custom sounds.
-Ice Cream Truck as a substitute Alarm Car.
-Various props such as a microphone and jukebox.
-Alternate paths.
-Scavenge Finale (In L4D).
-Scripted dialogue used to indicate how much Fuel has been deposited (as the interface can't normally be programmed for Scavenge play).
-Spectacular ending!

Cons:

-A little easy to get lost.
-Doors that require focus to open have Tank noises, even though no Tank appears (may be due to The Sacrifice's programming).
-Seeing as how there's a gun shop with Tier 2 Weapons in them early Map 2, the purpose of the one that emphasizes danger (the one near the start of the map) may be defeated.
-Tier 2 Weapons could wait a little longer in Map 2.
-Could use a few more Health Kit spawns scattered around the Maps (especially Map 3).
-Bots have trouble going down the manhole in Map 2 (on the street towards the sewers).
-Bots can easily get hurt by the fireplace in the house in Map 2.
-Easy to get lost in the sewers of Map 2.
-Tank music doesn't play in Map 3.
-Could use even more possible Pain Pill or Health Kit spawns in Map 3.
-I got really lost in Map 3 (in the tunnel, next to the police department). It wasn't very clear that I was supposed to shoot those black fuel tanks.
-Could use text messages for Crescendo Events (and for the Finale, just for those who haven't played L4D2).
-Huge stockpile at the start of Map 4 should be moved towards Finale area (at least, for the Health Kits).
-Should have a set of Health Kits and Weapons at the Gas Station in the Finale (perhaps inside the convenience store or near the Police Cruiser to be sure).

Conclusion:

A massive, massive campaign with lots of perks. It can get a little difficult and confusing in some paths though.

Pros:

-Long as a 5 map campaign, despite being only 4 maps long.
-Original environment.
-Finale is well-made.
-Elevator sequence is sweet!
-No excess or deficit of closets.
-Alternate routes, created even before L4D2 was even released.
-Exclusive to Left 4 Dead.

Cons:

-Lack of Health Kits in the beginning of Map 3.
-Could use a few more Ammo piles in levels 2 and 3.
-Lack of Survivor dialogue.
-Helicopter appears in the skybox as well as near the helipad.
-Bot Navigation in Finale is pretty poor; they tend to fall off the bunker walls and can't make heads or tails out of the quite simple path within.
-Breaks The Sacrifice's Tank spawn; disable the addon to solve this problem.

Conclusion:

Another well-made Campaign for L4D. Keep it exclusive to Left 4 Dead to keep people playing that game! Work on making it compatible with The Sacrifice's Tank Spawn to make it a keeper!

Pros:

-Dialogue at intro.
-Supplies sufficient.
-Bot navigation works.
-Hard to get lost.
-Believable environment.

Cons:

-No outstanding features.
-No dialogue anywhere else in the Campaign.
-Could use Survivors in the Poster (for the sake of player-survivor identification).
-Crescendo Switches remain lit up, even after activating them.
-Bots don't grab the Pistols at the start (this is negated by the extra Pistols in the next room).
-Lack of Submachine Guns in said room.
-Lack of Magnum Pistols.
-A few odd textures and doodads in Map 1.
-Could use some extra Pistols before the Finale (in case anyone starts at the third Map).
-Finale needs some work; Bots tend to fall in the manhole towards the sewer, hurting themselves.
-The final part of the Finale (where the music plays and everything goes to hell) should only start once the Survivors have reached the road. Otherwise, it's nigh-impossible to survive with a Tank in the river.
-I noticed a second Tank spawning while escaping through the river; this probably isn't welcome when fighting hordes in a river.
-Consider using Bile Bombs in place of the infinite Pipe Bombs.

Conclusion:

A nice Campaign the size of Crash Course. However, the finale needs some major improvements.

Pros:

-Maintains balanced gameplay even as a Half-Life chapter.
-Good crescendo events.
-Use of dialogue in certain parts.
-Enhancements added for various parts.
-Nice placement of supplies (although inspired by the original designers).
-Good use of music during the hospital scene (although it should have stuck with the track "What kind of Hospital is this?").
-Uncommon Infected.
-Storms in the third map.

Cons:

-Elevator crescendo feels a bit too short. Elevator sequence may be dangerous to laggy players.
-Survivor names for poster are out of place.
-Could use some dialogue for the radio (along with more dialogue in more parts).
-One time, one of the Survivors fell off the bridge without hanging onto the ledge (where Gordon meets Barney).
-No need for many Witches to be hanging around the first Safe Room.
-No radio dialogue (you can always replace it with something else).
-Dialogue at intro doesn't play during online matches (they do, however, play in Single Player).
-Gauntlet Event at Map 2 is a little tricky. Perhaps ease up on the mobs or move up the alarm door to make things easier. And don't try to use your own Special Infected spawns; it's challenging enough without them.
-Bots have trouble following down the hole after the Machine Gun (a Smoker got me and they failed to drop down).
-Only two Health Kits at the beginning of the last level (though compensated by the truck at the far end).
-Could use more Weapon variety in Safe Rooms.
-Combine Bodies no longer appear as of The Sacrifice Update.

Conclusion:

An example of how easy Half-Life city landscapes can be converted into Left 4 Dead.

Pros:

-Survivor dialogue at intro.
-New environments and ideas.
-Extra ways of transportation.
-No severe Bot navigation penalties.
-Health supplies sufficient.

Cons:

-Areas can be a bit too tight; Chargers and Spitters will have a field day!
-No scripted dialogue elsewhere in the campaign.
-There should be text notes in addition to glowing objects to indicate what they do. Of note is the tram, when I got left behind, not knowing what the switch in it does (I happened to explore outside the tram when it started moving).
-Too many Superweapons.
-Tier 2 Weapons should wait until Map 2.
-Bots will not follow into the Elevator in Map 2; this is compromised by having an alternative route through a precarious ladder in the shaft.
-There should be Tier 2 Weapons at the start of Map 3, instead of Tier 1 Weapons.
-Could use more Ammo or Guns spread out in Map 3.
-Map 3's tram should only start when everybody is inside. Have the tram model close the doors once everybody is aboard.
-Finale arena is insanely large; try cutting down some of the side rooms to make them smaller.

Conclusion:

An ordinary campaign that makes attempts at innovation (they work, but could use some polishing).

Pros:

-A nice orange map (Orange maps are always classics).
-Very linear and functional.
-Very entertaining.
-Supplies sufficient.

Cons:

-A bit too easy.
-Guns appear to be standing upward.
-No dialogue.
-No intro.
-Bots don't follow in finale (consider teleporting them when the player gets to the top of the tower).
-Boomers get themselves killed in the finale (try adding windows to the edges of the arenas).
-A few bot issues in some areas.

Conclusion:

I felt like reviewing this again since this campaign needs more reviews. Do you think you'll do a completely different orange campaign for Left 4 Dead 2, or are you going to stick with the port? We're all looking forward to the L4D2 version!

Pros:

-Great environment.
-Long length.
-Supplies and closets sufficient.
-Bot navigation not problematic.

Cons:

-A bit too long.
-Could use more Survivor dialogue.
-The tractor event at Map 4 tells players to start up the generator (or something. In any case, the notice is out of context).
-The hole that leads to the finale is a bit sudden, it incapacitated me.
-Possible to get lost.

Conclusion:

A nice, thorough campaign.

Pros:

-Remains loyal to its source material, yet adding L4D2's new features.
-Good use of Survivor dialogue.
-No notable supply issues.
-Music varies between levels.
-Formal Infected in the haunted mansion.
-Graffiti & Easter eggs.
-Ammo Packs, Defibrillators, Grenade Launchers, etc.

Cons:

-Custom sounds bugged (I'm aware you're finding a solution). I'd rather not use the rebuild sound cache command to hear them.
-Bots do not grab Health Kits at the beginning.
-Lack of hints for people new to this Campaign.
-Lack of Uncommon Infected.
-Expanding room in the mansion can be skipped.
-I once found a Witch in the way when I was escaping Moria (at the very end). Needless to say, this killed me.
-Moria level still hard! Ease it up a bit!
-Gauntlet Crescendos a bit vague; we need a button to shut the hordes off!
-Could use a Chainsaw/M60 for the Moria escape.
-Need warnings and notices for Crescendos. I didn't know the one in the second level was supposed to be a Gauntlet!

Conclusion:

Another welcome port! For the sounds, I think other custom Campaigns have managed to have custom sounds. Seek advice from those mapmakers!

Pros:

-Fairly good environment.
-Good gameplay.
-Unique panic events and Crescendo events.
-First level lacks secondary weapons, a bit of a twist.
-Handy notes for that one Medkit and events, also a boat ride.
-The addition of Mud Men.
-Plenty of supplies before the bridge event.
-Outhouses a good substitute for Closets.

Cons:

-There are less than four Health Kits in some Safe Rooms.
-Ammo Dumps absent in Safe Rooms.
-In the bridge event, there shouldn't be any Witches in the way!
-There should be a few spare weapons on the bridge with the Ammo dump in the truck.
-Could use Survivors in poster.
-Could use weapon placements in place of ammo dumps.
-Does there always have to be a Witch in front of the second map's gate?
-Witch behaviour is inconsistent with the time of day.
-Map 3 always has an Auto Shotgun on the planks at the start of the map (it may interfere with Mutations such as Gib Fest).
-Finale escape is a bit hard to get to, considering the holdout locations. Perhaps reduce the amount of "watery" areas.

Conclusion:

No doubt inspired by Swamp Fever I presume?

Keep up the good work.

Pros:

-Original environment.
-Bot navigation sufficient (naturally, they can't shoot the boss targets for you, but at least they'll protect you from the various Infected!).
-Unique bosses, as advertised.
-Infected music put to good use.
-Cutscene power to the max.
-Encourages teamwork.
-Ammo not an issue.
-Defibrillators provided in Arena in case anybody gets run over by the worm.
-Various Uncommon Infected.
-No glitches I can think of.
-Dynamic intro.

Cons:

-Survivor names in poster are completely inverted.
-No scripted Survivor dialogue.
-A bit challenging with Bots, even on Easy!
-Could use another set of Health Kits at the escape pod, and a few more in the Arena.
-Could use some Pistols in the Arena or Escape Pod, in case anyone perishes.
-Boss Infected shouldn't appear on this map (a Witch tends to spawn from the beginning to the Arena).
-Could use some spare Primary Weapons in the Escape Pod, in case anyone wishes to switch.
-Skybox in the corridor kind of messes up.
-Finale Music upon reaching the Escape Pod sort of overlaps.

Conclusion:

A tense, though entertaining map. I'm almost absolute that this entry will win the Boss contest!

Pros:

-No gameplay issues.
-Bots are functional.
-No supply issues.
-Hazmat Infected.
-Small size, easy download.
-Summoning Helicopter though a laptop, original.
-Labyrinth event is randomized.

Cons:

-No Ammo Packs, Defibrillators, or Superweapons.
-A spelling mistake on the second level's Crescendo event.
-After escaping the labyrinth event, there should be a notice to get back to the surface.
-Purple reflections in third level.
-Skybox acts a little weird (maybe it's just my computer).
-No level-specific Survivor dialogue.
-No music for hordes and safe rooms save for the usual drums.
-No introduction sequence.
-Tier 2 Weapons should be available later in the campaign, not in the first level.
-Invisible objects post-Sacrifice. Needs to be updated to address these issues.

Conclusion:

A campaign that resembles Dead Center and The Parish in places. Not bad, although it could use some polishing. Please update this in order to compensate for The Sacrifice's changes.

Pros:

-Another Payload map. This time the Survivors ACTUALLY need to push the cart instead of searching for Fuel Cans.
-Closets stealthily integrated in spawn rooms.
-Construction and Fallen Survivor Infected fit well here.
-Announcer dialogue.

Cons:

-Bots fail to recognize cart as an Ammo Dump.
-Bots can be pretty stupid sometimes (quite a few dethroning moments of stupidity).
-Map could be turned into a three-map Campaign.
-Crescendo Events a little unknown. Add some notices to make them more obvious, or allow a break to let the Survivors explore.
-Lack of Survivor dialogue.
-Lack of an intro sequence.
-TOO many zombie attacks! Give the Survivors a break in between!
-TOO MANY SPECIAL INFECTED! I could never stop seeing duplicates!
-Health Kits missing in the second spawning room.

Conclusion:

Still a bit necessary to tweak down the amount of hordes (enable moments of silence for Survivors to have a chance to advance) and Special Infected. Having too many Special Infected come at a time is like playing Hard Eight, and that isn't at all fun.

Pros:

-Short download
-Crescendo Event explained in second map
-No ammo issues

Cons:

-Skybox a bit glitchy (things tend to pop up randomly)
-Survivors' names in poster are out of place
-Images for first two maps are glitched
-Crescendo Event in second map gets a bit overwhelming in the last phase
-Lack of starting weapon variety
-Sometimes easy to get lost. Use lights as well as arrows to guide the Survivors' way through
-Lack of Survivor dialogue
-Lack of Ammo Packs and Defibrillators
-Could use more Adrenaline Shots & Pills
-Dead ends should have extra supplies

Conclusion:

An average, generic campaign.

Pros:

-Many types of Uncommon Infected, all of them suited to their locations.
-Nice introduction sequence.
-Superweapons and Ammo Boxes are present. Defibrillators too.
-A bit of Survivor dialogue here and there.
-Hard Rain music suits the map well.
-Finale is very unique, but insanely difficult.
-Environment is nice.

Cons:

-Campaign is a bit difficult at times.
-When coming out of a manhole, some of the bots fell to their incapacitation. Think you could split the ladder in two to prevent any bot accidents?
-The horde arriving after collecting the fuel cans is insanely overwhelming. There's no need for a Tank to be present too.
-WAY too many Special Infected. I often saw doubles of certain types!
-There are no Health Kits in the sewers! I was on the brink of death before reaching the level's Safe Room!
-Could use a few warnings before Crescendo Events.
-Witch behaviour inconsistent with time of day in some levels, may be due to balance.
-Could use Survivors in the poster.
-Bots are too dumb to live in map 4 event and finale (Coach fell off to his death in the bridge and Ellis was being useless with his pistols as usual).
-Desperately need more Pipe Bombs and Bile Bombs in the finale.

Conclusion:

A lot of original ideas were put into this campaign, but sadly, the gameplay falters due to the Bots' stupidity. For the finale, lots of Pipe Bombs and Bile Bombs are pretty much mandatory. You REALLY need to fix the amounts of Special Infected in this Campaign.

Pros:

-Functioning, no bot or technical issues.
-Custom Sounds.
-Indiana Jones theme is used for credits.
-Ride is fun (and functioning), and there are not many supply issues.
-Environment is great.
-Scavenge portion in the ride.

Cons:

-A little too easy.
-No zombies spawn when the car is actually moving.
-There should be a Tank that spawns during the ride.
-Should be more music from the game here (you know, how each official Campaign has its own zombie alert track?).
-No Uncommon Infected.
-No Survivor dialogue other than at the intro.

Conclusion:

A fun, though not so serious and not so L4D-ish campaign.

Pros:

-Features another cameo of the L4D Survivors.
-Hazmat and Riot Infected.
-No gameplay issues. No Bot navigation issues for the most part.
-Ammo and Weapons sufficient in maps.
-Arrows and lights guide the way.
-Unique Crescendo Event with the field of Alarm Cars (put in the impound lot line for extra effectiveness).

Cons:

-Crescendo Event in map 2 is delayed.
-One time, a Witch fell through the water in the third map while chasing me. In the same map, Survivors are unable to hold onto the ledge near the water.
-Survivors' names in poster are out of place.
-Bot navigation for map 1's manhole is questionable (Rochelle was too dumb to live).
-Could use notices for crescendo events.
-Could use more medical supplies in Map 3.

Conclusion:

A campaign with unique features and no significant disadvantages. Work on modifying the events to make them work better.

Pros:

-Campaign takes place in a vessel throughout.
-A little bit of Survivor dialogue here and there.
-Atmosphere immersive and level design well-made.
-Weapon placement good.

Cons:

-Is it me, or do the hordes in the third map never stop after opening the gate?
-Lack of Health Kits in areas (especially map 3).
-Only two Health Kits in finale.
-A bit easy to get lost.

Conclusion:

It's a little easy to get lost in this map, seeing as how you can easily backtrack in certain areas. Otherwise, it's a nice, dark Campaign.

Pros:

-Level design was functonal and well-paced.
-Environments believable.
-Train ride is functional.
-Stash at the first level is not easy to miss; bots grab the supplies too.
-Fairly linear.

Cons:

-Bots tend to stop at certain places and get stuck at others.
-Could use a few Health Kits in the middle of levels.
-Bots aren't meant to tackle the dropping section; it's easy to get into the "ledge hanging" mode.
-Finale a little bit too open and bland.
-Why does the Poster say "Dead Line"?

Conclusion:

Another generic campaign with a few good features.

Pros:

-Custom skins and sounds do not overlap to other Campaigns (see "Freezer Burn" for more details).
-Good environment.
-No urgent supply issues.
-Sufficient AI navigation.
-Signs can guide the players.
-Uncommon Infected.

Cons:

-Survivors' names in poster are out of place.
-Lack of Pistols beyond first level (no Magnum Pistols at all!).
-Could use more direct notices for Crescendo Events.
-Lack of dialogue other than in the intro.
-Third level occasionally crashes.
-Finale can be abused by bringing the Fuel Cans to the boat.
-Boat in finale is hard to find. Finale area is easy to get lost in.
-Just at the end of the third level, there should be more ladders to get on top of the rooftops; I had to navigate a long way to get back up.
-Numerous spelling mistakes.

Conclusion:

A nice campaign. For the sake of those who wish to use the default skins and sounds, you should make them separate from this campaign.

Pros:

-Stays true to TF2 design without many gameplay issues.
-Functional cart, no problems with it.
-Unique gameplay.
-Instructional notices.
-Infected tend to go after the cart rather than the Survivors. It gives them a good breather moment.

Cons:

-No Witches.
-Lack of Uncommon Infected. I'd think that the Fallen Survivor would work well here.

Conclusion:

A nice wacky map. Do you think you will continue to develop this map? And will you do the same for other TF2 maps?

Pros:

-No notable gameplay issues. One-way passages, sufficient supplies, and horde-drawing events all spread out appropriately.
-APC rescue vehicle makes a good departure from the traditional helicopter.
-Supply cabinets rigged with alarms, a clever trick!
-No notable graphical issues.

Cons:

-Lack of Survivor dialogue.
-Lack of intro and safe room music.
-Crescendo warnings should stay in their traditional formats. Still thoughtful to put them in nonetheless.
-One time, the APC ran over poor Bill (after he got killed before we got to the finale!).
-Could use a few warnings for the cabinet events.
-Bots sometimes don't pick up the Health Kits.

Conclusion:

A well-working campaign.

Pros:

-Fun gameplay.
-Very good placement of Machine Guns!
-Sufficient primary and melee weapons.
-Sufficient Grenades, Consumables, and plenty of Health Kits.
-Nice placement of Construction Infected in finale and second portion of the second level.
-Finale looks nice. Gameplay wise, it could have improvement, but still good.
-Hard to get lost.

Cons:

-Lack of pistols.
-Having to fight a Tank AND a horde in the finale? That's crazy!
-A few misplaced textures.
-Some not-so-good wall textures.
-WAY too many zombies in getting to the helipad.
-A bit of framerate problems at the beginning of the second map.
-Could use the Survivors in the poster.
-A little too wide open in the finale.
-Sometimes Health Kits will go missing in the Safe Rooms.
-Infected spawn in Finale BEFORE activating the radio.

Conclusion:

Lots of potential in this short, Crash Course-esque Campaign. I think fighting two Tanks at once should stay in Swamp Fever, but overall it was a worthwhile campaign. As for the finale, I kind of went back for the machine guns, but in doing so, I would become trapped by the Tanks. I had to rescue bot Coach, but, unfortunately, the Tank kept going through the only exit, out of that region, the building. Perhaps you could consider adding multiple ways out of that area!

Pros:

-Unique sounds.
-Good gameplay.
-Supplies reasonably scattered throughout.
-Environments are immense, albeit irrelevant every time.

Cons:

-Moria ending is very overwhelming. Let the Survivors reach the end of the bridge before spawning the enemies, okay?
-Lack of Survivor dialogue.

Conclusion:

My old review got lost, so I made this one.

Pros:

-Has plenty of potential.
-Walking portion is not neglected.
-Alternate ways to go through this map.
-Handy notice for unique map notes.
-Script on the boat plants the Bots on the boat; no navigation issues (save for a few bots getting off the boat sometimes).

Cons:

-The boat should stop every once in a while in order for the Survivors to refresh on ammo. Make a few gates that the Survivors must open to encourage them to take a breather!
-Lack of crescendo events on the boat ride. Use gates for this also.
-I kind of rushed at the end by jumping off the boat. I couldn't get back on when we were back at the station.
-Environment is sketchy at times.
-No Tanks or Witches.
-The Infected in the environment can be a bit distracting. Perhaps you could use other models?
-No custom dialogue.
-Lack of Uncommon Infected.
-Lack of Closets, especially near the ride itself.
-No Ammo Packs or Superweapons.
-Could use a bit of music near the end.

Conclusion:

It's a nice campaign, albeit in need of significant updates. I've heard of this ride. It's nice that you included the maintenance rooms and side areas for exploration, but perhaps you could implement them into the ride mode as well. As for the Uncommons, I think the Fallen Survivor works best, seeing as how you must plunder on the ship. Also, think you could put in some Pirates of the Caribbean music at the crescendo event (if you haven't already)? If you can't get your hands on that, why not use The Passing's theme?

Pros:

-Puzzle Elements a fair departure from common gameplay.
-No supply shortages. They were plentiful.
-Presence of Laser Sight installers.
-Presence of Uncommon Infected (Riot).
-Puzzles were very creative.
-A very elaborate introduction sequence.
-No notable bot issues (other than the bridge).

Cons:

-VERY easy to get lost in (how 'bout putting in some signs?).
-Riot Infected don't really fit into the environment all that well (maybe Hazmat Infected would work better).
-The bridge over...yellow water (ugh) gave me lots of problems in single player, as the Bots tend to knock over the object off the button, killing them instantly.
-I noticed an alarming lack of closets. You really should put lots in.
-There should be a notice for the finale.
-Lack of dialogue.
-There may be too many Ammo Packs. You might want to replace them with other weapons to vary things up a bit.
-Item placements (especially Weapon placements) don't change.
-Textures are a bit dull.
-Necessary items spawn instantly; one could shoot a Gas Can and it would create a perpetual fire!

Conclusion:

An original Campaign (save for the Portal inspiration). Keep working on this campaign to make it better! For the object and button puzzles, perhaps you could use items such as Gnome Chompski or some Cola.

Pros:

-Decent length
-Decent Machine Gun locations
-Dialogue.
-No extreme problems in ammo placement (although maybe the third map may be lacking).
-Alternate routes in the second level.

Cons:

-A few bugs in collisions
-Some missing textures, (possibly unsatisfactory framerate and ping levels)
-Lack of Medkits in the construction area.
-Lack of Uncommon Infected.
-Bots wander off at the beginning.

Conclusion:

My first campaign downloaded for L4D2. It was a decent run, although there are still improvements to be worked on.

Pros:

-Nice, not too difficult.
-Bots are functional.
-Use of dialogue throughout Campaign.
-The elevator can go back down just in case anybody gets left behind.
-The presence of Uncommon Infected (Riot Infected), a notable aversion of a common oversight.

Cons:

-Auto Shotgun FAR too early in the Campaign.
-A few too many supplies. Vary it up a little!
-A little easy to get lost in the Finale.
-Survivor names for poster are out of place.

Conclusion:

A nice Campaign. Putting a few rails on the lift when it goes up would prevent anyone from getting left behind. Otherwise, this is a nice, but ordinary Campaign.

Pros:

-Fantastic environment
-Good use of in-game and custom dialogue
-Versatile gameplay
-Functional bots.

Cons:

-Not enough pistols
-A bit too foggy
-Supplies all over the place in the finale
-Tank skin requires toggling of addon
-Bots may not take Health Kits in certain Safe Rooms
-Lack of Health Kits at the beginning of the last level. 
-Not enough supplies in the metal detector level
-Lack of Uncommon Infected
-Fire may be abused by a Charger, as I was incapacitated due to being stuck in the fire.

Conclusion:

A good campaign, has lots and lots of potential. Good work on using a Hard Rain style of going through the level. Please add more pistols throughout the levels, as I could hardly find any to accompany my Shotgun. Also, try limiting the space in the finale, as it's difficult to find supplies. A notice to trigger the finale would be nice.
