Pros:

-A lot of places to explore.
-New challenges, bridge lowering and gascan events before the end of the campaign.
-Unique saferooms.
-Long chapters
-Very cool areas to run around
-Lots of throwables.

Cons:

-Very repetitive.
-Bot nav isn't the best, kept having Nick get stuck everywhere and dying.
-Every tank we had spawned near cars, had a few wipes due to it throwing cars (not your fault, just annoying lol)
-Cut and paste some sections right out of Death Toll and Dead Air.
-Multiple horde events on each map made it a little too challenging.
-Tons of first aid kits did offset the horde events, but I got very frustrated.
-Map levels were a tad bland.
-Some z fighting and lighting errors here and there, as well as some cubemap errors.
-The part in map 3 where you have to hit the radio to fill up the tank...it was pointing to the actual radio on the table when it wanted you to click the radio on the dead soldier. Took me a long time to figure it out.

Conclusion:

It's a good map, but it got so repetitive that it could barely hold my interest when I was playing it. It needs to be less "city maze run run run run" and needs more unique atmospheres. I did love the tank event, though. Very cool. The whole map needs to be cool though, I almost stopped playing because I was bored. :\

Pros:

-Minecraft!
-Amazing detail
-Funny/realistic horde events
-Long
-Short loading times, always a plus.

Cons:

-I was getting a lot of FPS lag on the finale on top of one of the mountains.
-Some places are a tad too dark.
-Lack of directional arrows

Conclusion:

I did a play through of this campaign and I'm going to be uploading it to YouTube soon. Amazing job, it came out wonderful. It's got everything a Minecrafter could ask for.

Pros:

Map 1-
-Interesting Into
-Very spacious
-Large maps
-Custom music

Map 2-
-A lot of Chinese aspects like signs and lights.
-Unique music again
-Creepy ambiance made it feel deserted.
-Looting zombies was a great touch
-Soldiers shooting you was pretty awesome
-Cola bottles for molotovs was pretty cool
-Custom Witch skin

Map 3-
-Very unique and long finale
-Good balance of weapons
-Nice area to fight horde
-Plenty of room to maneuver around
-Awesome outro scene

Cons:

Map 1- 
-Z-fighting in the skybox from the window of the saferoom
-Few nav errors here and there
-No prop physics on the computers and such.
-Odd fire textures and smoke can be seen through the wall
-Needs more ammo
-Helicopter animation in the skybox is on a loop and looks silly.
-No collision on the ladder going up in the elevator shaft.
-Z-fighting on the plywood boards in the end saferoom

Map 2-
-Really really dark
-I'm not sure if this was accidental, but your water texture in the fountain looks VERY similar to a texture from Suicide Blitz 2's Portal easter egg.
-Very very few ammo piles.
-Zombie's ragdoll's go through fences and garbage cans (prop dynamic)
-Specials had a hard time navigating the cars.
-No collision on the railings on the stairwell leading up to a room.
-A building from the skybox comes onto the street, looks really bad.
-z-fighting on the sidewalk on the street.

Map 3-
-Lighting on the pipe in the sewer  near the ladder was weird.
-Floating M60 in one of the CEDA tents.
-A little warning that moving the plow wasn't the actual finale would have been helpful.
-More grenades would have been useful
-There was a good minute and a half delay in the time between when the finale was over and when we could get into the rescue vehicle...it was really bad.

Conclusion:

I did enjoy this campaign, it was just a little rough in some areas. It seems rushed in some of the parts (small things that fell through the cracks), but they aren't too severe to impact game play. I'm not sure if you're going to update again, but I think that fixing some of the texture and ambient errors would help make this campaign epic. :)

Pros:

-Nice replacement
-Great pictures
-Looks official

Cons:

-Zoey's looks a little derpy, but it's hardly noticeable.
-Would have preferred smiles, but understandable why not.

Conclusion:

I was waiting for someone to do this, and thank you. :)

Pros:

-Great layout.
-Amazing design.
-Unique environments.
-Custom music sets the environment.
-Great horde events
-Plenty of supplies and weapons.

Cons:

-I think it was the 1st chapter, one of the rooms has an "ERROR" for a model (a light I believe).
-I noticed quite a handful of nav errors, as well as a "jesus spot" on the finale. Bots being bots, falling off ledges and falling back down ladders.
-I noticed a lot of lighting problems on textures.
-3rd chapter ending saferoom, bots kept trying to close the door and locking themselves out. They wouldn't get inside.
-Zombies disappear in map 4 right after you kill them.
-As well, I noticed something weird with the water on that map...it makes the blur effects on models on the boat look weird.
-Need more instructions on what to do in the sewer, as well as where the balloon comes in the finale.

Conclusion:

I have a recording of the playthrough of your map on my Livestream account, I make note of all the errors I found here....if you're interested as to what I found. If not, I have a screenshot of the jesus spot on the finale and the model error I can PM to you. Otherwise, it's a great port to L4D2 of a good campaign. :)

Pros:

-Great custom items
-Nice scenery
-Beautiful finale idea
-Awesome campaign poster, it looks epic
-Unique beginning area and custom models
-A lot of custom skins
-Custom graffiti
-Interesting horde events
-Custom posters and pictures
-Awesome easter egg!

Cons:

-Your nav is a lot better, but there is still a few errors (Tank nav in the easter egg).
-Ammo is pretty scarce, as well as good melee weapons.
-No teir 2 weapons until wayyy later on (still occurs, but I don't think you're going to fix it.)
-The 3rd chapter seemed a little dull, repetitive.
-I was getting a lot of FPS as well as internet lag on this campaign. Needed to restart 6+ times to get it to work (and even then I had a 200-300 ping and 20fps). Not sure if it was the map, but I've never had that problem before.
-Custom infected (the guys with the jerseys on) have square shadows.
-Your finale is a little buggy, including both Tanks spawning at the exact same time and exact same area.

Conclusion:

All in all, it's good, and the update fixed a lot of errors. Again, I love the atmosphere and it came out great!

Pros:

-Pokemon music
-Awesome idea

Cons:

-It's only music.

Conclusion:

You need to specify in your title that this is just music, not a complete sound pack for the Tank.
Other than that, it's great. Made me laugh a little because I have the Demonik Tank sounds. It sounded really funny.

Pros:

-Great atmosphere
-L4D1 survivors (I love you)
-Feels like Half Life ^_^
-Perfect amount of supplies
-Challenging
-Custom items and props.
-Nice maze-like level deisgn
-Gnome of Awesomeness!
-I saw a ship with the name "Relentless". I LOL'd.

Cons:

-The Gnome can be a little glitchy (the toxic shield doesn't seem to work)
-The final level is too long, and once the gate is opened, you're screwed. I was with 1 other person (we deleted the bots) and we didn't make it past there on Easy.
-Are you supposed to lose the gnome on the 3rd chapter beginning saferoom?
-You're missing one pixel of texture on the floor on the dock of the warehouse in the shipyard level.
-Bot infected can get stuck here and there, but nothing too bad.
-Bot infected can also set off horde events.

Conclusion:

Overall, I really had fun playing this. Nothing like huddling around a gnome and hearing him laugh like a maniac while he lights zombies on fire. :D Definitely worth a download.

Pros:

-Amazing atmosphere
-Great custom textures and effects
-New melee weapon (OMG LOVEEE IT!)
-Custom music
-Nice balance for item and ammo spawning
-Great horde events 
-Water textures near the boat horde were so realistic
-Loooooong
-Custom Tank model for finale (I loved it so much)
-Custom voice acting made it very nice

Cons:

-Bot nav problems getting on Crazy Rob's train.
-Framerate lag during horde and fire areas.
-Long loading time

Conclusion:

I....I really am still in awe. I just played this about 15 minutes ago, and it has to be one of the most epic campaigns I've played in a while. So much custom material made the game play absolutely unforgettable. It felt a lot different than the L4D1 version, and the improvements can really be seen. It took me about an hour and a half to finish it, and that is the PERFECT length. This needs to get featured by Valve. All in all, amazing campaign and I would like to congratulate you on my first 100 rating. :)

Pros:

-Custom things
-Funny moments
-Awesome ideas for the gascans and getting weapons
-The ending was amazing
-Awesome gameplay
-The final scene was EPIC
-Very Portal-esque.

Cons:

-Bots kinda derp on this map, especially when you make your way down the pipes with the hanging cars.
-The laser part moves too quickly and bots don't avoid them at all.
-Quite a lot of zombies, in my opinion.
-The Tanks in that one room with the painting was a little too much.

Conclusion:

Overall, I really enjoyed this campaign. It had a lot of funny and awesome stuff and I really enjoyed the ending segement and the Portal-like feel of the game. Very well done!

Pros:

-Interesting idea for a map.
-A few custom things.
-Believeable story line.
-Pleantiful supplies.
-Large areas to explore.
-Skeletonssss!

Cons:

-A little bland
-The jukebox didn't platy BYOB, I even rebuilt my audio cache and it still won't work.
-A lot of map glitches which let you skip areas.
-Wall writing is kind of stupid, it needs to look like someone wrote it, not that someone copy and pasted it from MSPaint.

Conclusion:

It was a little boring in my opinion, lacking detail and there were a few glitches. I was really disappointed (as well as everyone else here probably) that the jukebox doesn't work, so that should be high on the list of patches you should do. Also, as far as the advertising about the "offical review team", I'm friends with Austin (Kilplix)...and well...I hope you asked permission before putting his name in your map.

Pros:

-Great design
-Nice, a snow map.
-Big maps.
-Acceptable amount of supplies.
-Great finale design.
-Long maps.

Cons:

-Really confusing.
-Easy to get lost.
-At one point at the end of the first chapter, I kept getting horde after horde, with no letting up. Even with the difficulty on Easy we barely made it to the saferoom (which was like 100 feet away).
-Ammo was a little scarce, but it was ok.
-I found a shortcut and I was able to go into places you aren't supposed to go. The maps weren't very one-directional.
-I had both Tanks get trapped on the stair area under the helipad...easy kill.
-The elvator goes up without all people on, and won't go  back down.
-The ladder going down the hill to the area where the finale takes place is a death trap. You don't catch the ladder and fall to your death.

Conclusion:

It was an okay map. Lacking a few design elements here and there (it got really repetative), and some special infected spawns are messed up. Very easy to get lost and not a lot of direction. Spray some arrows down, get the horde events under control and fix a lot of the glitches, and it'll be a great map.

Pros:

-Awesome ambient horde events (plane crash, train going through, ect...)
-LONG chapters.
-Just enough supplies (ammo, medkits, pills, grenades) until the final chapter.
-No bot nav issues.
-Car showroom was nice, great product placement XD
-Cool 2nd chapter saferoom ending.
-Custom areas and unique designs
-Placement of weapons, grenades, and health packs makes sense.
-Zombies falling made me jump a few times. hahaha
-Nice placement of Tanks and Witches, just enough.

Cons:

-A little repetative in the beginning.
-I had a HUGE horde at the plane crash.
-Lack of double pistols.
-3rd chapter, the zombies run into the fire of the barricade, making the horde really easy.
-I watched the Tank spawn at the top of a fence in the 3rd chapter.
-You need to put more ammo in the 3rd chapter. I ran out half-way through the last chapter. I only had double pistols until the very end where you set off the finale.
-I had sooo many Boomers in the finale. I think there was 12 in the finale alone, and 42 for the entire campaign. O_O

Conclusion:

Great map with an awesome playthrough. You need to fix a couple things on the final chapter...and it might have been advisable to split up the chapters, you could have made a 5-chapter campaign out of this. It was a great map, only a few problems with ammo and spawning of infected...BUT completely worth the download. :)

Pros:

-Amazing design
-A defianate challenge
-Unique atmosphere
-Custom horde events
-Great item placement
-Just enough ammo to get you through.

Cons:

-This is impossible to survive with bots.
-The finale is challenging, a little bit too challenging. Getting attacked by a Charger or Hunter or anything that grabs you means you will probably die if you aren't saved within 3-5 seconds.

Conclusion:

This was amazing. I played it with 1 other person on Normal and we needed to change the difficulty to easy to make it through the finale. Great design and one of the top campaigns I've ever played. Bravo. :)

Pros:

-All around good map
-Nice item placements
-Interesting details and terrain
-Long chapters
-Plenty of ammo and grenades
-The train horde was really neat.
-Multiple paths and dead ends make it enjoyable

Cons:

-It took the bots about 5 minutes to grab their medkits and weapons in the 1st chapter spawn area. It was torture.
-I had a few hordes spawn in rooms I was in, which wasn't fun.
-Some of the map transitions don't make sense...like an industrial tunnel leads into a residence?
-The edges of the map were too close to where you were walking, so you could see the 2D tree outlines really close.
-No instructions for horde events.
-The 2nd chapter was kind of repetitive, it felt like I was running through the first chapter of Blood Harvest for 20 minutes.
-Too many Tanks. I had 4 in one chapter.
-Not sure if it's on purpose, but at the end of the 4th chapter, I had Witch music with no Witch...it was weird.
-Finale was kind of boring, in my opinion.

Conclusion:

This was a great map and well worth a download. Some minor graphic and ambient surrounding glitches were present, but some were barely noticable. It did become a little repetitive in the middle chapters, but it has variety. Good campaign, focus on the small ambient details next time. :)

Pros:

-Very well made.
-Great storyline.
-Realistic item placement (gas cans next to a gas pump).
-A lot of custom designs and grafitti.

Cons:

-Only one map completed.
-The bots jump into the electrified water before the power can be shut off (but who gives a crap, it was a great idea).

Conclusion:

It was great! I loved the playthrough and it's a great idea for a storyline. I look forward to the completed map!

Pros:

-Great Gameplay
-Easy to explore without getting too lost
-Hot tub :D

Cons:

-Bot navigation was horrible. My bots kept teleporting everywhere.
-No directional arrows on any of the chapters, it took me 15 minutes to find the sewer opening.
-Copy and pasted a lot of items and areas from the offical L4D campaigns.
-Purple hue around a lot of buildings.
-No teir 2 weapons in any of the later saferooms.
-Weird arrangement of the finale...it got me confused.
-In chapter 4, please don't have that horde event door on fire. The bots want to run to the saferoom, but the door is on fire while it's going up...2 of my bots killed themselves.
-The tractor horde event is another one, no direction prompting you to hit the lever on the tractor (as well as Bill bot died because he was in front of it...it was funny...but still needs fixing).
-The maps are too short and a little boring.
-Not a lot of custom things.
-There were a lot of graphic glitches and things missing.
-Special infected spawning was bad as well, I had a Tank spawn outside the emergency doors, and he couldn't get in, just a sittng duck...and I heard numerous specials die.

Conclusion:

There were a lot of problems I saw with this map, but it's worth a download if you like the regular Left 4 Dead campaigns with a twist.
Fix some of the glitches, bot nav, add your own stuff, and I'll amend my rating.

Pros:

- Custom graffiti.
- Interesting backstory and it's fun trying to figure out where you're going.
- Finale was amazing!
- Scarce resources makes for quite a challenge.
- The custom desert setting and tomb setting was very well done.
- Well designed custom horde events made it very enjoyable.

Cons:

- A couple sound and voice glitches, but nothing too noticable.
- It got a little repetitive in the middle chapters.
- The last chapter, the big ladder you need to climb down to get to the tombs, I had 2 bots jump off and incap themselves, and one was hanging off the edge. They did it each time I played through.
- I found about 4 throwables in the entire campaign. That's way too few.
- Both Tanks I got in the finale were on fire...and I don't know how.

Conclusion:

It was a well made map and it is a very fun campaign. The ending sequence was a little odd, but the finale was epic. Definately worth the download.

Pros:

-Unique
-A lot of space to explore certian areas.
- A varitey of terrains provides nice exploration.
- Easy on harder difficulties.
- Nice variety of short and long chapters.
- Creepy realistic atmosphere.

Cons:

-Bot navigation was a real problem in this one. Constant teleporting and setting off car alarms.
-It is so dark, I got lost 3 times outside the saferoom in the first chapter.
-  I started the van, but it didn't let me push it. The van doesn't work. I tried everything, even blowing it up. It was a nice idea, but you should have tested it before putting it in.
- I got killed by the train (not the rescure train) on the last chapter.
- I think it's either the first or second chapter, there's a gap in the fence at one point that shouldn't be there. I ended up going to the edge of the map.
- There was almost no Witches or Tanks.
- I'm not sure if it was the map's fault, but Fraps didn't let me record my playthrough of it. I've tried a few times, but it's just your map that Fraps doesn't work with.

Conclusion:

It's a well made campaign, and it has a lot of custom stuff in it. The deisgner needs to do some MAJOR patching, but overall it was a nice playthrough.

Pros:

-Amazing custom content.
-Great detail in the shipwreck, cliff, and prison.

Cons:

-Clipping issues.
-The shipwreck made me disorientated.
-The balloon was a nice touch, but the first time you play it you have to find where the balloon comes, and that involves running from the top of the lighthouse to the dock. It's a real pain running down those stairs with specials, commons, and Tanks coming at you.

Conclusion:

Great campaign, only a few minor issues.

Pros:

-Amazing custom content.
-The prison was very accurate (I used to work in one).
-Neat horde events.
-Epic elevator music. :D
-Custom audio was spectacular.
-The train was an amazing addition to an already well made campaign.

Cons:

-The finale is challenging, due to the fact that there is no way to sit in a corner and fight the horde.
-When it comes to the streets, it was a little blah. No real detail and custom things.
-Lack of ammo.

Conclusion:

Packed full of custom stuff, and great for multiple playthroughs.

Pros:

-Amazing detail.
-Voices of all survivors are used, and are funny.
-The custom work on this was just insanely awesome.
-Nice easter egg in the finale.
-There were a lot of funny custom saferoom wall writings that made me laugh so hard.
-Challenging, but not absurd.
-Multiple paths make for replayability.

Cons:

-I had a Tank spawn right at the rescue vehicle, making me have to sacrifice one of my bots so I could make it ( but who really cares about bots, anyways?)
-Very large file, took me over an hour to download it.

Conclusion:

Amazing playthrough and amazing work.
C'est magnifique!

Pros:

-Amazing design.
-A lot of custom stuff and voices are all over the map.
-The Haunted Mansion was an amazing render of the actual one.
-A lot of funny wall writings and paintings.
-Each chapter was different in theme, and each one had it's own unique feel.

Cons:

-The campaign really didn't flow for me.
-A couple of glitches with bot navigation, but nothing too extreme.
-Sound for the Haunted Mansion is broken.
-You still have to hold down "E" even after the progress bar is gone (even though you said it would be fixed).
-There was a lot of lack of direction, and I got lost a few times.

Conclusion:

Amazing campaign, but needs more direction and needs a few glitches fixed.

Pros:

-Exactly like the Silent Hill campaign.
-Very challenging.
-A lot of scary parts.
-It was neat how the Witch was encorporated in.
-Lack of ammo really makes this a challenging but enjoyable playthrough.

Cons:

-Don't play the finale with bots unless you have God mode on.
-The position of the glyphs changes and they are very difficult to find.
-One chapter campaign, if you die, you lose everything and have to start over.
-The finale was...odd...
-Lack of direction and just an odd feeling of confusion throughout the entire campaign.

Conclusion:

This is bascially the same as Silent Hill's first chapter, only with ghost Witches making an appearence and you have to look for glyphs, not keys. I would have rather just played the Silent Hill map again.

Pros:

-Amazingly accurate.
-Kept the same monsters as Silent Hill.
-Scary
-This campaign really makes you think. Unlike other ones, where you just run and shoot zombies.
-Puzzles are really fun and challenging.
-There are multiple versions and I've played it numerous times and I have yet to have the same experience twice.

Cons:

-Extrememly long, it took me 7 hours my first playthrough.
-There are a lot of places to fall off/hang off ledges all over.
-Very very very easy to get lost.
-Don't count on seeing much, the visibility is near nothing.
-Barely any ammo.
-If you've never played Silent Hill the game, you'll be completely lost.
-There is a lot of lack of direction at some points, I ended up having to use noclip at a point because I couldn't find a key to the door anywhere.

Conclusion:

Very good campaign if you have the time and patience to be stumped and scared. It offers something a lot different than the normal custom campaigns...fear.
It was amazing and I loved it.
