Pros:

It works online. And has incap animations.

Cons:

Ellis has black head
Untextured holster for Nick, Ellis and Coach
Nick lost human-like animation for G3 alias Military Sniper

Conclusion:

11/10 for just working online.

Pros:

Huge amount of lines added for each Survivor – I'm still wondering why Valve didn't do it, I mean why the f♥♥k you would record megabytes of dialogues just to NOT use it at all?
You can say „Sorry” for friendly fire and you can actually hear a response like „God damn it.” or sth
Wisely used „Thanks” response when healing (Survivors are thanking when you're healing them, not after to avoid cutting lines)
Nice try with using „battle healing” lines, but pretty much unsuccessful (they actually appear after horde attacks)
„Got a can” instead of „Got it“ spam
I didn't know that Coach's „This used to be a nice neighborhood!” was actually implemented into game, I thought it's only in intro :D

Cons:

In any mutation with one Survivor dialogues goes crazy – e.g. in The Streets Survivor randomly and at any time says lines from level start about going to gun shop – it's weird when you're standing in front of Whitaker's shop and e.g. Coach says that there is gun shop in the town and they should go there
In The Passing Nick sometimes wants to shoot Francis even if they was talking with Zoey
In NM1 Francis very often answers to himself (like „Safehouse! Let's go!” and right then he says „Cool.” or „A-frickin-men.” like first line was said by other Survivor)

Conclusion:

It definitely works in Single Player and if you're not a fan of custom radial menus (like me), it's definitely worth a shot.

Pros:

Pure beauty
Long (took me almost 40 minutes)
Good optimization (FPS dropped a bit, but not to unplayable level)
Bots worked fine… mostly
Clever Crescendo Event
Interesting use of saferoom doors
Just purely fun to play :)

Cons:

Total lack of ammo pickups
Dark as hell (but it's self-explanatory)
Kingdom for Hunting Rifle
In most cases I wasn't entirely sure where I can jump without getting killed
On this first kind-of-bridge Francis lost navigation and half of map I was going with two bots until game finally decided to at least teleport it to my place (which was next to drill)
The place I was saying above is way to easy to defend as it's hardly believable that one bot with single pistol dropped down entire horde on Advanced difficulty
Where was Auto Shotgun? When I dropped down to this maze before drill, I found out Bill and Louis are running with auto shotties
Absurdly easy (but still effective) finale, just stand with Hunting Rifle on bridge and after killing Tank go for ammo

Conclusion:

Fun meter filled to 110% level

Pros:

Pretty much copy-paste from my review for L4D2 version:

„Very enjoyable map layout
Length of campaign is just fine - not too short and not too long”
„Very cool finale - despite that I personally hate scavenge finales, I really enjoyed playing it especially that it is much better than rest of campaign”

Cons:

Like wise.

„Déjà vu on 1st map - highly resembles No Mercy to me
Dumb placement of weapons (shitload of them just before points of no return) and alarmed cars
I wonder why horde attacked after leaving train on 2nd level” – actually, now I'm not as I heard police sirens which could cause an horde attack – still, Tank isn't necessary there
„ONE weapon pickup in finale (looks like someone forgot that when Tank kills Survivor, weapon also gets punched and flies couple of feet away - good luck with finding it)” – well, L4D1 version doesn't have any
„Didn't like ventilation shafts - I was just waiting for Spitter or Charger to f♥♥k me up” – while there wasn't any Spitters or Chargers, I still didn't feel much comfortable in vent shafts, too much „Half-Life'ish” for me

Conclusion:

Overall, though, it felt much better than L4D2 version – I'm guessing it's because I wasn't running out of shotgun ammo every 5 minutes and even with limping from gunshop with bleed-out 1 HP and later Tank in saferoom I managed to successfully pass campaign, so it doesn't appear as a fail in my opinion :D

Pros:

Something for L4D1
HMG on 1st map instead of minigun
Shitload of dialogues, few unused lines also made an appearance
I always liked generators finale
Wisely thought start point (meaning it doesn't look like Survivors came to the point from direction they're heading for now)
Good placement of Hunting Rifles
Pretty easy
Credits worked
(+/-) Cool idea with supply crates
(+/-) Good placement of stationary guns

Cons:

(+/-) Without jumping on crate you probably won't see what's inside it
(+/-) No explanation on how crates magically opened after map transition
(+/-) Statguns are pretty overpowered as they're placed in a way that bots can perfectly cover your back (excluding the one on 2nd (?) map – 2nd screen)
Unbelievable amount of invisible walls
Unnecessary signs about getting lost in forest – either invisible walls are blocking players or you have to only take one corner to get to the place (1st map)
I expected to have more than 2 Boomers behind „Boomer-infested Gate”
Draw distance destroys graphics (trees and building behind fog etc.)
No textures in few places
Very bland design (excluding 1st and last map), passing the same corridors through 30 minutes isn't my favourite
It lagged a little somewhere in forest, near this kind of pond – few infected moved in water and suddenly game dropped to 20 FPS
Bots refuse to take ammo and additional pistols, also forget about them taking anything from crates
They hardly keep up in finale and passionately goes to dead ends when chased by Tank
Lack of Special Infected of all kinds, but when they do appear, they sit in places you totally can't avoid them (vide Smoker jumping out of corner and instantly choking you)
„Completely optional event” is pretty much unnecessary as it's hard to fail in this campaign

Conclusion:

Maybe too much idiotic-proof, but overall it's fun to play and definitely worth downloading, it wouldn't be a bad idea also if you would make another campaign for ye olde L4D1 as you definitely know what you're doing.

Pros:

Glocks! Does it need any more explanation?

Cons:

L4D2 shooting sound ain't my favourite and definitely ain't the best
Pistols don't fit into arms in first person (fingers are holding… pretty much nothing)
No worldmodel, but it's due to no pak01_dir.vpk edit

Conclusion:

It could be a little bigger to fit into hands, but overall nice addition, good if you will somehow get bored of Colts.

Pros:

Pretty much like original
A real sunny campaign is what L4D1 needed so much

Cons:

Tons of downloading, good thing I finally changed my hard drive to bigger one :)
Throwables only in finale
Pills only in health stations + 1 bottle in hotel, in front of elevator in trash can
Bots hardly pick up anything and don't keep up at all (while I'm at 2nd floor trying to get gas can, bots are running for pills lying on table)
They are really useless when it comes to an event – when I was running with cola, bots just stood in front of shop
Gas cans are almost impossible to pick up (oddly enough, doesn't apply to cans in finale)
Respawning gas cans in finale, so sometimes it's just better to put 6 to 8 gas cans and then wait until closest gas cans respawn
Instead of doing some weirdly flickering broken laser sights it would be better to just not put anything there (eventually ammo pile)
No health packs in Whitaker's shop

Conclusion:

Had to cheat in finale when counter hit 10 as bots were much more interested in pills rather than covering me and letting themselves cover, which was quickly punished by Hunter and I didn't want to again make this deadly run.
Waiting for fixes and next campaigns. 

Pros:

I don't remember any glitches
Fits Ellis' dumb behavior as stupid redneck even better than original
Nice hat, Stetson-like

Cons:

I don't remember any

Conclusion:

I remember this from Silent Hill: Otherside of Life campaign (Leafo and poorly working GCFScape forced me to play with this) and... uh... I don't feel good with giving it 10, but I wouldn't be honest if I would rate it lower than I should

Pros:

Probably the best Arby's reanimation
Works well with higher FOV (no autorefilling magazine and clipping hands)

Cons:

Luckily none

Conclusion:

Yeah, definitely worth downloading.

Pros:

Very detailed
Arby's animation is pretty good
With Killing Floor sounds it's so fun to play with it

Cons:

No flashlight

Conclusion:

I wonder if someone, someday will make GL with changed animations so they'll fit old reload time

Pros:

Plain M4
Actually, doesn't look that dang big like on screens (but I thought it will be more compact)

Cons:

Like Recoup said, shooting animation feels weird, like recoil is pushing weapon on sides instead of going up
Like people said earlier, no shells eject (albeit it's not that visible in game)
I think it would use better with default animations, but with actual gun position (why no one made this yet? people are complaining that animations are very hard to do, why not changing the most annoying things with keeping rest as default as possible to not give yourself additional work?)
No custom sounds (original M16 ain't fitting that well)

Conclusion:

For now it's my best replacement for default M16, but I still look for some good weapon models to make L4D2 actually good game (why everything which is first is always the best... In L4D1 I have only Team Health Counter and Modified Talker installed)

Pros:

Phew, got rid of one of ugliest things in L4D2
Flawless (albeit it would be hard to mess sth with replacing a couple of files)

Cons:

Nah

Conclusion:

"You did good."

Pros:

This skin gives me back hope that not every skin has to be cathegorized as manga or mature
Rochelle magically stopped to annoy me
Haircut actually moves when running, like in case of Zoey (forgot how this is "properly" named... wait a minute, I think I got it - it's jiggle bones, right? lol)
Purse also moves
Now Nick can take care of business ;)

Cons:

Purse is moving all the time, even when Rochelle is standing
Putting pistols in purse was a great idea, but it doesn't work with Survivors Movement Animation Fix - pistols appears on back, clipping through it and shaking like bag
Is it only me or she has bruised left eye?
Oh, forgot 'bout one thing: flying adrenaline, it's just attached to her too far away... from her

Conclusion:

OK, here are screens:
Adrenaline + pistol: http://s18.postimg.org/wiplzh01l/2013_08_16_00004.jpg
Magnum: http://s12.postimg.org/sow0rmh5p/2013_08_16_00006.jpg
As for me purse ain't fitting pretty much, holsters for pistols would be just enough.

Pros:

Everything, it is just better than original - more climatic, harder, but with balanced difficulty, with better weapon spawns (I mean in The Parish players are spammed with weapons)... It would be too long to list everything

Cons:

Flying jets at night look at least weird
Still no ammo pile just before bridge
Deleting almost all items from last saferoom is also bad idea - it would be better to swap 4 medkits to e.g. one or two defibrillators and temporary healing items, saving one or two throwables would also do the trick (I had problems with finding any in 3rd and 4th map)

Conclusion:

"Nice job."

Pros:

Wide, open spaces
Huge finale area with nice amount of healing items scattered here and there
Long (can't say how long I played it, though, I'll explain later why)
Good amount of weapons and health items considering openness of maps - if you'll search good, you shouldn't fail (I played it with Improved Bots on Advanced and didn't have almost none trouble)
Snipers will love this campaign

Cons:

Bots are not taking almost anything
Invisible walls
Glitched Crescendo Event with gate - for no reason horde attacked me BEFORE I actually pushed the button (Francis was yelling about kickstarting generator, which also wasn't fitting at all), also somehow Louis got launched couple of feet away behind gate and got killed by Hunter
Zombies respawning at your face - both when situation is calm and when horde is attacking
In last saferoom I got katana in weapons cache... horizontally, also somewhere M60 was clipping through cache AND through wall

Conclusion:

Thanks to my internet provider and idiotic behavior of Steam game disconnected me with "No Steam logon" communicate at the end of 1st wave in finale despite playing in Single Player...
Nonetheless, it's my top 1  - definitely it doesn't worth 10/10, but from campaigns I've recently played, this one was the best for me, so I think pulling rate a little isn't anything bad.

Pros:

Looks good, really good
Wisely thought Crescendos
First two maps and first half of 3rd

Cons:

Last map is one big fail - loses all impression, dull action (shoot everything that moves), unnecessary Gauntlet, Special Infected spam, rescue didn't happen (fading to black? rly?) - I wish I didn't play it...
...especially that game crashed when loading it after 3rd map - dunno wtf is happening, from last 5 campaigns I've downloaded and played only Dam it 2! didn't crashed and was bug-free
Levitating weapons on 2nd map
Bots weren't taking medkits on last map
Second half of 3rd map (generators) was plain, boring and unsuccessful
Lags after throwing Molotov/shooting at gas can
Pointing to saferoom is good, but putting safehouse spray every 5 metres makes me feel like I'm playing Call of Duty
No voice from radio

Conclusion:

If you'll play this, play only first three maps - when you'll finally get to the surface, just turn the game off. Otherwise you'll get a huge disappointment when playing finale.
Remember, kidz - graphics is not everything

Pros:

Bugfree
Pistols scattered throughout maps
Good Survivors dialogues
Acceptable amount of weapons
Really liked finale area
Lack of Boss Infected (I can't imagine fighting Tank in that tight areas)

Cons:

Odd start point - I mean it looks like Survivors came there from direction they're heading for
SI spam, especially in finale and on Elevator Crescendo
In finale only Spitters, Chargers and Hunters were spawning = kingdom for laser sight, also I was surprised that none of bots got punched out of dam
On 1st Event on 2nd map game spawned Tank, which incapacitated one bot and... disappeared
Event on 1st map spawned 3 hordes at once
Almost none health supplies
No ammo piles on 1st map and in saferooms
Maybe slightly too dark, could use some more lights in buildings
Oh, and bots didn't pick up medkits in finale

Conclusion:

Overall: I really liked this campaign (what kinda surprised me) despite huge amounts of Special Infected and fact that I didn't know where helicopter will land. Maybe making that roof look like a helipad would do the trick?
"Almost finished making map1 longer" - don't. Unless you're gonna put pills and ammo pile somewhere there.

Pros:

AI worked pretty much good, but, unfortunately, not always
Looks great... usually
Pistols are pretty easy to find on map
Complicated in good sense of this word - often there is more than one path available
Dialogues for Survivors, especially liked it because it's helpful like "down the stairs, up that ladder" so player can ensure himself that he goes in good direction
Dat size

Cons:

AI got stuck after tower event
Crash after 3rd map (caused by lost internet connection), all bots hanging on a sniper tower and Tank throwing rocks through stairs successfully took all my intentions to finish this campaign (not to mention Coach running for Hunting Rifle just to hang on a ledge instead of picking up Spas from locker near generator)
Sometimes too dark, sometimes lacks action a little, but not that much
Scavenge finales ain't my favourites

Conclusion:

As always, the only Tank which appeared through campaign had to show with a horde in tight area just before Crescendo Event on 2nd map (or 3rd one, it was so long I don't remember which one was that - tower event)
Rating would be higher, but that crash and total AI fail in finale took all the impression from gameplay.

Pros:

Great 1st map, 2nd was good too, albeit too long for me, had to use 2 defibrillators (at least I was forced to use it)
Music perfectly fitting into gameplay - however, it's hard to hear it
Good idea with custom melee weapons, but shovel could use some custom sounds (the only game with usable shovel I know is Postal 2)
Dialogues for Survivors (but about 20% of them were glitched - there was caption, but none of Survivors were talking, in console there wasn't any errors)

Cons:

Jesus, next custom campaign with stupid aversion to pistols (3 single pickups on 1st map... and that's all)
Smoker sounds were glitching
Witch sounds were just annoying, model itself was... well, as for me it would be better to stay with default model
Absurd amount of medkits from 4th map, players can heal beneath 70 HP and still won't spend them all
Not even one helpful sign of where to go on 4-6th maps
Crash after loading 5th map, 4 hours wasted
Next 2 hours wasted on pointless running on 6th map, which ended by noclipping through last door
What happened to Zoey? Honestly, I expected to find her later in campaign somewhere in Otherworld - it turned out campaign went in totally different direction
Ending... short version: FAIL, long version: pseudo-philosophical gibberish about life, definitely wasn't satisfying after 6 hours of playing 
1st thought after going down by elevator - "What the f♥♥k is this? 2001: A Space Travesty?"
1st thought after seeing 7th map: "Oh great, now we're in Matrix... Or maybe it is Portal? Anyway, still better than Spaceballs"
Well... No finale

Conclusion:

Huge disappointment in comparison with 1st Silent Hill campaign. 4/10 only because of music and great first 2 maps.

Pros:

It just looks better than original shottie despite having visually worse texture, I don't know why Valve was changing its model to more... boring one
Arby's animations (L4D1 one aren't working)
More different model than default Chrome Shotgun

Cons:

Sound is too powerful for this shotgun

Conclusion:

As for me it's definitely a must-have

Pros:

Not much better than original animations, but reloading seems to be more realistic
Gun position

Cons:

Floating bullet when reloading Uzi (use "host_timescale 0.1" to see what I mean)
Glitched grab animations - instead of e.g. shotguns, where animations doesn't exist at all, here you can hear sound of changing position of hands, but weapon stays totally still, with no motions at all
Running animations are weird
Again, thumb on L4D1 Survivors' hands

Conclusion:

If someone got too much used to default animations, he may not like this, but nonetheless it's good reanimation. It's not flawless, but I'm still using it cause those little bugs aren't too much noticeable.

Pros:

Really good 1st map, albeit it could be more straight
Challenging
Good looking environment, some decals are looking really nice
Works well as a lullaby

Cons:

Idiotic Gauntlet on 2nd map (Nürburgring has less turns than that warehouse or whatever it was)
3rd map... I don't remember anything more boring than this
4 Crescendos on 3rd map caused by... dunno, motion sensors? Smell of Bill's beard? It wasn't anything I could see or hear
Shitload of alarmed cars
Bots failed with getting into chopper

Conclusion:

Way, WAY better than Escape From Valencia. Still, I don't see any replayability potential here. Unless you have problems with sleeping.

And one note: despite all it's boringness, it took me 85 minutes to finish this campaign - exactly the same like in case of EFV. Well, at least I laughed at the end :)

Pros:

At last normal pistols with no useless attachments and fancy (CZ75) or unfitting animations
Fits ideally for pistol slot (ammo capacity and firepower due to used caliber)
Animations are ideal for USP (it's not big pistol and on those animations every pistol I've seen looked too small)
No custom sounds = doesn't have to mess with .vpk

Cons:

As usually, looks weird in L4D1 Survivors' hands on viewmodel (it looks like they are clipping through hand like if pistols would be placed too close to screen)

Conclusion:

A winner is you.

Pros:

Very enjoyable map layout
Length of campaign is just fine - not too short and not too long
No Gauntet Events (unless sth screwed up)
Very cool finale - despite that I personally hate scavenge finales, I really enjoyed playing it especially that it is much better than rest of campaign

Cons:

Déjà vu on 1st map - highly resembles No Mercy to me
Dumb placement of weapons (shitload of them just before points of no return) and alarmed cars
I wonder why horde attacked after leaving train on 2nd level (ignore Tank attacking with horde and fact that literally 5 minutes later second one appeared)
ONE weapon pickup in finale (looks like someone forgot that when Tank kills Survivor, weapon also gets punched and flies couple of feet away - good luck with finding it)
Spawning Tank just behind your back when you're watching pictures on projector is the most idiotic idea I've ever seen in any campaign
Oh God, not again alarmed doors - even more annoying is fact that it doesn't instantly open, but after some stupid and unnecessary delay
Bot-unfriendly (they don't pickup weapons and ammo on last map)
Didn't like ventilation shafts - I was just waiting for Spitter or Charger to f♥♥k me up

Conclusion:

If I would play with default bots, it wouldn't get even 4 points. Hell, I've felt that they were doing better than me...

Pros:

No bugs
Looks very good
L4D1 Survivors (most of campaigns I've recently downloaded have new Survivors)
Decent amount of weapons
No nav errors
Custom graffiti

Cons:

Boring
Small, short and still I was getting lost through whole campaign (maybe a little more than one arrow per map?)
Some pointing to docks would be very useful (of course I went to totally opposite direction and failed after pretty easy finale, but it's hard to remember one sign when you're limping and trying to escape from Tank)
Unless you don't have to restart anything, there shouldn't be any smoke from generators - after seeing smoke near them and seeing sign about manually restarting generators if they fail I thought it'll be Crash Course-like finale = even more time lost during 5th wave
No dialogues
No defibs, lasers, ammo upgrades, medkits, throwables
Bad Tanks spawn in finale (just loved to sit on ammo pile)

Conclusion:

Disappointed. It is overall not bad campaign, but it doesn't have anything distinctive (besides nice look of the maps)

Pros:

Great concept
Light size
Some cool gameplay details like low gravity in one point and alternate routes on some jumping parts so if you fall down, you don't have to come back and jump once again
Shitload of weapons and supplies
Breaking blocks to get items is the coolest thing I've ever seen in custom campaigns
Game actually awards players if they want to explore map (I mean 4 hidden medkits on 2nd map)
I was amazed on how well bots worked on this map - despite this I preferred to just stop them before platforms and teleport to stable ground
Very nicely made finale map, also rescue "vehicle" was a great idea
Dead Mario squished under collapsed tubes was one of funniest things I've seen in game :)

Cons:

On 3rd map, when you're getting deeply low after starting point it's very easy to hang on a ledge at the top of that... huh, tower-thing?
After last update (July 2, 2013) flame castle is next-to-unplayable cause of incredibly bright screen - flame trap in corridor is actually impossible to see
For some reason map didn't want to start at first time - I was getting an error about none map specified, but never mind - it worked after restarting game.
I like easier maps more than "challenging" ones, but Crescendo Event on generator in 2nd map spawned only 15-20 zombies

Conclusion:

After all, campaign is actually bug-free, very funny to play and not too much hard. Deserved rating 10.
And this was said by guy who hates Super Mario Bros. game. :P

Pros:

3 maps, but as long as any other campaign
Good design and few cool ideas (like flares), I liked especially 1st map
Fits very well into L4D2's "plot", could be canonical (for me it would be much more worth officially releasing it as some kind of DLC than Cold Stream)
Survivors talks! Dialogues are one of coolest things in game and in many custom campaigns Survivors are speechless (besides usual lines like "Reloading!" and all)
Yea, skybox was very good - AFAIR this is first campaign set at afternoon
Custom graffities - sometimes very funny to read (like "I MISS YOUTUBE"), but usually it looks too good - like it was written by painter
Secondaries pickups through whole campaign - big plus cause people are often forgetting about pistols

Cons:

Tank spawned right at the beginning of the level - good thing I started map from console (so I started on Normal difficulty, but played on Advanced)
It took me a while how to get to the ladder in that dark place on 1st map
Inaccessible throwable in alarm control room (like RainingMetal said), also for no reason game showed me "You picked up Incendiary Ammunition and "You picked up Explosive ammunition" right after disabling alarm (didn't happen on 2nd gameplay)
I almost got f♥♥ked up at the end of finale cause I couldn't reach dumpster (I thought I have to go down and find some ladder or sth) - fortunately, neither Special Infected nor Horde spawned (there were few zombies and Tank, which got rid of bots)
Dunno if this is AID fault, but after restart on 2nd map amount of supplies drastically reduced - at first time I found 1 medkit and 3 bottles of pills right outside of saferoom, next 2 medkits in ambulance and 2 bottles of pills through level and one bottle on gauntlet, after restart I found 2 adrenaline shots through whole level and all ambulances were empty
Lack of defibrillators

Conclusion:

Would be 10, if not that stupid Tank on Panic Event - I had it at 1st time and after restart it was in exactly the same place, so assume it's scripted to sit and f♥♥k you there. I'll play it few times more, however, to make sure.

One odd thing that happened to me was in saferoom on last map - when I wanted to teleport bots to weapons, somehow I teleported outside of room, to inaccessible part of map... Of course, I couldn't get back in the same way - I had to noclip.

EDIT: Rate +1, as I said earlier, cause now there wasn't Tank on Gauntlet (meaning it's not scripted to actually be there, I just had incredible no-luck twice in a row). Also, 1 defibrillator spawned (unfortunately, I had to use it literally 5 minutes later).
So, mostly AI Director fu♥♥ed everything.

EDIT2: Editing again cause I forgot to say that I am not getting any stats at the end of campaign (only time played is available, rest of stats are all showed as 0)

Pros:

That's how it should look like by default

Cons:

None

Conclusion:

At 1st I thought that floating health when incapacitated will look weird, but it turned out to have even better visibility than by default! A real must-have for every L4D2 player.

Pros:

Good first 3 maps and finale, albeit maybe even too easy
Pistol at start of campaign (which somehow is not a standard in all campaigns)
Mirrors HL2: Episode One (my favorite one) very well
Light size

Cons:

Gauntlet on second map is impossible to pass without melee weapon, and I'm myself more of pistols fan
3 Witches on 1st map (at least these were wandering ones)
4th map way too long
No pickup for pistol or Magnum on 3rd map
Lack of supplies, which was bothering me cause I remember pretty well where was supply crates in HL2 game
No for 2 Tanks in finale (maybe it wasn't my day, but I finished alone, in black&white mode and with cheated pills :P But I wanted to just finish it after really exhausting 4th map and finale, so maybe I had bad attitude)
Idiotproof in case of ammo - losing all ammo when you do manage to survive gauntlet is just impossible
Didn't like storm on 3rd map

Conclusion:

After encouraging 1st map and restart on second (Witch + Gauntlet - melee weapon = constant fail) I got enjoyed until entering hospital. Then I started thinking "F♥♥k... How long is this map?!" and I got even disappointed upon seeing only 2 medkits in saferoom. Finale area was pretty well made, but actually it wasn't easy to holdout there - getting anywhere higher would take too much time, so places were pretty much limited to supplies point and train tracks. Now I think I shouldda drop down there and try to survive on lower point, but without melee weapon it would probably fail too.

Overall, campaign nevertheless is good, but actually I didn't enjoyed it as much as I expected. I wanted to give 8, but gave 8.5 - otherwise it could be too much subjective mark.

EDIT: As always, on second thought I reminded myself of many things in campaign I didn't write about at 1st time.
- On gauntlet that wrecked car, from which you have to jump to get to alarm is too far away and is too low - it needs some attention to jump there and it's very hard when you're getting swarmed. Some kind of damaged truck would fit there better
- I had big problems with finding alarm switcher despite having Game Instructor enabled (not even stupid arrow)
- Zombies were blocking on that net on the right side of gate on highest floor
- Horde was still spawning 2 minutes after disabling alarm
- On last map, when you're arriving at hangar or sth... never mind - the point is when Smoker grabs you when you're standing on collapsed walkway you'll be instantly choked
- Again, supplies (especially in hospital I didn't find... huh, actually I didn't find pretty much anything - only 1 medkit and 1 adrenaline shot somewhere close to saferoom) - I found bottle of pills on first map and I used it in finale

Pros:

Pretty long
After all very detailed (see cons for explanation)
Surprisingly well worked with bots
Wisely placed weapons and ammo on first two maps
Finale map in Cold Stream style (whole map is one big gauntlet), but not as next-to-impossible to do as in said campaign
Small size of file (it's important for me as... well, I am trying to get new hard drive and I can't force myself to do so :D)

Cons:

If there wouldn't be any description here, I wouldn't have any idea what Survivors are doing in that complex
Definitely too much explosive barrels + one glitched in finale (released twice as much fire as it should and I almost burned to death) and only one was placed in helpful place (the last one - shooting it blocks one path entirely, giving some time to Survivors)
Second map was too long, at the end it was just plain boring, also I got lost on it (it turned out I had to go into ventilation shaft in ceiling)
I would place some pistols in second map (I don't remember even one pickup of neither Glock or Magnum)
I don't have any idea what caused Crescendo Event on 1st map - some alarm or sth would do the trick (I disabled music, if this could be a reason)
No ammo in finale (I don't know how the hell I passed it on Advanced with only pistols)
Flying car... I forgot when I felt so disappointed after finishing any campaign in L4D

Conclusion:

I played it for about 80 minutes and I didn't waste even one second - very cool campaign, enjoyable, playable with bots and even finale was... huh, fully positive - except for rescue vehicle. So easy to fix: make some gate behind car and spin it 180 degrees, so it will face that gate. Maybe it will look too much like Dead Center, but at least it won't be weird.

EDIT: OK, it seems that ERROR signs was due to last update, also graphics somehow changed on my PC, so I edited review a little. Maybe +0.1 as those errors wasn't author's fault.

Pros:

Love that melee push - now it looks like pushing rather than hitting a fly like on default models
More aggressive pumping style
Pump at the end of reload looks cool despite that it's not realistic
Works flawlessly also with L4D1 survivors
Reloading looks more active
Camera shaking - hating it in B2L4D2 Scar, hating it in B2L4D2 Deagle, here it doesn't f♥♥k up everything

Cons:

No grab animation (still better lacking of them like having it glitched like on your Mini-14)
Hard to have fun with using them when you still have only 56 shells in reserve :(

Conclusion:

Looks very cool, works as it should. Approved :)

Pros:

Default pistols = nothing to screw up
Good set of animation chosen, fits P220/Glock pair pretty well

Cons:

Slightly too small - although not as annoying and weird as on e.g. M1911s, when you'll draw primary weapon, it'll look huge :P (-0.1)
Some probably non-useful files in .vpk (none points taken since average user won't notice it)

Conclusion:

Must-have for those who liked anyway L4D2's original pistols (like me :P)

Pros:

No spinning wrist bug
Just reanimation, not messed up by new model/texture/sound/[put what you want here]
Much better shooting animation - really makes Mini-14 easier to handle when weapon isn't flying all over your screen like it would be some freaking RPG
Perfectly fit for 3rd person animation

Cons:

Got used to additional pushing magazine - now it looks too big for me (none points taken since it's some step to make weapon more realistic)
Left arm looks... weird. I don't know, it's only subjective feeling only - nvm
You could stay with old drawing animation (-0.1)

EDIT: Forgot about 2 things: thumb of original Survivors (-0) and glitched "helping arm/pick up item" animation (-0.1) - both of them are exactly the same on ported from CS:S SG552. Coincidence?

Conclusion:

One of few arby's reanimations I liked

Pros:

Weapons are really scarce, which makes gameplay acceptably hard (pistols are usually easy to find)
Veeery long (it took me sth about 6-7 hours to finish it from start)
Survival is more important than shooting (meaning there is less "run & gun" than in original game)
Puzzles aren't that hard especially if you have walkthrough (I used it few times since I have never played any of Silent Hill games)
Very possible to pass it with improved bots (but nothing higher than Normal if you want to still have some fun from playing game)

Cons:

Messed up zombies spawning (mostly on 7th map) - I had sometimes situation where I passed one place and after just turning around I had up to 20 wandering zombies spawned - too much fog? (-0.5)
From what I remember from SH walkthrough for L4D1 campaign, on 7th map it should be almost pitch-black - I had good lighting and very much fog, which resulted in awkward appearance of map (none points taken since it wasn't much easier)
On 7th map script still drops L4D1 Survivors' bodies (-0.1 since it's only small detail)
Glitches The Passing for me (none points taken since disabling addon works good enough)
Bots stumbling on doors - especially annoying on said 7th map (where you have one point of no return and I had situation with one bot behind that doors which permanently closes in one moment - good thing I could teleport it to room) (none points taken)
Bots doesn't take anything (excluding some pistols in normal world and last pickup weapons on 11th map) (none points taken thanks to Improved Bots mod)
Bad navigation on #4 ending (the one with cow and UFO) - bots have huge problems with getting onto roofs (surprisingly enough, infected also) (none points taken despite that I almost failed on 5th wave)
"Rescue arrived! Get aboard!" spam (actually, +0.1 since it looks funny :P)
Very unpleasant gameplay when Director will decide to spam Chargers and Spitters :/ (none points taken since it's Valve fault :P)

Conclusion:

Great 6 hours, I really liked this campaign, big shame none of my friends doesn't even have Left 4 Dead :(
Don't count pros and cons, it's because of my character that there is much more - than + :P
Oh, and one advise: if you somehow got lost on map, always turn left - it worked for me - I was even surprised by how easy it was to find keys on 1st map, rest of campaign also wasn't that hard
In short words: play it - you won't be disappointed.
