Pros:

A huge step forward for the least-likeable character in L4D history.

Cons:

None.

Conclusion:

Damn, look at that hair! This mod is astounding, not to mention pleasing to the eye. You did a great job on this one.

Pros:

-Great atmosphere
-Interesting "split-up" intro
-Cool new panic events
-Nice difficulty curve
-Multiple paths 
-Dialogue
-There's actual replay value
-Custom melee
-SNOW!

Cons:

-I wouldn't say that the sacrifice finale is a con, but I was disappointed when I had to kill myself after all that work
-The finale might be too difficult with bots only
-I accidentally threw a cog behind the generator, and I couldn't retrieve it, thus having to start over
-Kept getting lost in the first map
-The intro is nice, but a bit too long
-Not enough throwables

Conclusion:

I actually genuinely loved this campaign, and made my 4th of July ten times better. I can't wait for fixes and additions to this one!

Pros:

-Great design
-Compact, but not claughstraphobic
-Lots of supplies, items, and weapons
-You can fall back if you need to

Cons:

-None I can see, other than fps, but that's my computer's fault

Conclusion:

I'd play this over any survival map! Its hella worth downloading!

Pros:

-Superb detail
-Amazing atmosphere
-Improvements from beta
-Great level design

Cons:

-Confusing finale 
-Lots of places where you can get stuck
-Some places where you can leave the map
-Too few crescendo events

Conclusion:

This is one of my favorite campaigns! It's definitely one of the most detailed campaigns out there, but it can be better. There's too many places where I said "Where the hell do I go??".

Pros:

Beautiful animations
Great high-quality sounds

Cons:

The reload borks up on non-local servers.

Conclusion:

Doktor and Arby must be so jealous right now! If you or someone else fixes the reload, then this is an automatic 10/10!

Pros:

Best thing ever.

Cons:

None.

Conclusion:

Do a soundpack for JonTron. NOW. DOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOITDOIT

Pros:

-Fits Nick's style
-Reminds me of Vegas
-He really is "Mr. Gamblin' Man"
-Extra scar on his face

Cons:

-No normals
-Colors are a bit too bright, especially the jeans.

Conclusion:

I love this mod, expect many reskins of it ;)

Pros:

-Nostalgasm
-Flawless barricade system
-Great music
-Keeps true to original movie
-Not too easy, but not ridiculously hard
-Nice supply of items
-Fun with bots and/or friends

Cons:

-Lags to an almost unplayable state when a Tank spawns

Conclusion:

Other than the earth-shattering Tank lag, this is a beautiful masterpiece. This is honestly one of my favorites.

Pros:

-Half-Life (obviously)
-Lots of nostalgia
-The blood textures were a nice touch
-Fastest-running campaign (aka no lag)

Cons:

-Some missing textures
-Lighting is sometimes wonky
-Bot nav could use some work
-Too claustrophobic for tanks and witches
-Weapon placement was weird
-Saferoom finale...?
-Underwhelming levels
-Levels are obviously too short
-Huge file with unecessary content

Conclusion:

It may be a Half-Life campaign, but HL2 maps weren't made for L4D2. The level design clashes with L4D2's game mechanics, thus making it less fun then it should be. The finale also confused me; I waited in the saferoom until the escape music started playing, and then the level ended. I love the concept of remaking Half-Life 2 levels into L4D2, but this campaign was executed rather poorly.

Pros:

Catchy music
Somehow fits in with L4D2

Cons:

None

Conclusion:

Honestly, this is an upgrade from the default L4D2 music. The music makes the experience more epic.

Pros:

-Actual facial animations!
-FPS arms
-Jigglebones are a nice touch
-High quality!

Cons:

-Ellis voice doesn't fit well (-0.1)
-Personally, it should have replaced Nick (-0)
-The boomer textures, but I know how hard that is to deal with (-0)
-Melee animations are broken (-0.4)

Conclusion:

Almost flawless! This is my new favorite.
But please, fix the melee anims.

Pros:

-Very detailed
-It's from BF3 :D

Cons:

-nope.avi

Conclusion:

One of the best retextures out there. I highly recommend this one!

Pros:

-Makes the overall theme a little less "South-y"
-Makes S.I. encounters more scary
-Goes great with my cinematic mod
-Fixed volume

Cons:

-None

Conclusion:

Very sick mod, you did well. The Boomer's themes are by far my favorite.

Pros:

-Somehow fits the hunter's personality
-Very nice blood and stains
-Makes the hunter "pop out" from the rest of the world and easier to spot

Cons:

-None that I can see

Conclusion:

Very nice mod, and I can't wait for Life's a Beach!

Pros:

-Based off of actual shirt
-Good textures

Cons:

-Doesn't really fit Ellis's character

Conclusion:

Nice mod, way better than what I can do.

Pros:

-More sounds
-Better in my opinion
-Makes the Jockey creepier and sound more like a zombie

Cons:

-None

Conclusion:

Great mod, coming from a great developer! I recommend this if you are bored with the normal Jockey.

Pros:

-Epic campaign for an epic book
-great atmosphere
-Some hordes were challenging
-In desperate times, forced you to search for supplies
-Wide open spaces

Cons:

-Bots are average to dumb
-On the chapter with the saferoom near the barn, bots refused to enter the saferoom.
-Wide spaces don't do justice for special infected (except Tanks)
-Some map glitches

Conclusion:

All in all, this is a stupendous campaign. Only problems I see are map and nav based. Other than that, good work mate.

Pros:

It's Resident Evil :D
Great atmosphere
Very good challenge
Involves quick decision making
Lots of explosive barrels + gas cans

Cons:

Little variety of weapons
You don't have time to set up
The barricade system is useless (more in conclusion)
Needs a better skybox
Lag issues

Conclusion:

This is one of my favorite survival maps, but it needs some polishing if it wants to do better. The barricade system is pointless if you don't have time to set up. Other than that, this is a great map.

Pros:

-It suits Nick and his personality
-Good quality
-Nice choice of colors

Cons:

-Too clean and polished

Conclusion:

My new favorite mod for Nick! An update with blemishes, stains, rips, and other imperfections in the clothing would be nice though.

Pros:

-Awesome sounds
-Makes every weapon sound more powerful

Cons:

-Glitched up sounds in almost every single weapon

Conclusion:

Great mod overall, but please fix the sound frequencies. I'm adding this to my watch list until the bugs are fixed...

Pros:

-Just awesome.
-Better than original.
-Valve should have fixed this first!

Cons:

-None

Conclusion:

Unless you have a Deagle mod, this is perfect. Get this no matter what.

Pros:

The animations are a nice touch
Better than the original
The color indicates that it's a health item (similar to the health kit's color)

Cons:

None

Conclusion:

Magnificent job. Keep up the good work ;)

Pros:

It's The Walking Dead
It actually works
It goes well with the L4D2 atmosphere
The images were well chosen

Cons:

None

Conclusion:

Great mod! The Walking Dead franchise really ties in with L4D2.

Pros:

+It's actually legit fun
+It's lengthy
+Weapons/items
+You can choose the background music :D
+Intro and outro
+Custom sound events (scared the pants off of me the first time I heard it :D)
+Great concept

Cons:

-Not much of a challenge, could use some crescendo events
-No witches
-Not many tanks

Conclusion:

This is one of the first real GOOD maze maps I've seen so far, all it needs is a challenge curve. If you can expand on this concept and make a full-out campaign, then I would love you forever :'D

Pros:

Looks like the Ellis from E3
Good quality

Cons:

The colors are too saturated
"Beta" Ellis also had a green hat

Conclusion:

It's good, but it could be better.

Pros:

I like the feel of it.
High resolution model.
Great textures.
It's Resident Evil. I mean, c'mon.

Cons:

Sometimes hands are visible, sometimes they aren't.

Conclusion:

Very well done, the only problem is what I said earlier. It happens at random. It's not a big deal, I just wish it would be fixed.

Pros:

Great port
Way better than the original pistols
Asymmetrical

Cons:

Uses original sounds

Conclusion:

Very good port to L4D2, I recommend this to everyone.

Pros:

It works!
Very useful
Everyone should get this
Bots are less dumb!

Cons:

None

Conclusion:

Amazing mod! I recommend this to everyone, especially people who ride solo.

Pros:

Stays true to the original
Challenging
Lengthy
Very good atmosphere
Puzzles
Nice boss fights
Forces you to ration ammo (yes, that's a good thing)
Mini-crescendos (specials appear when you pick an item up)

Cons:

No melee weapons
Weird zombie spawning (explained in conclusion)
Cannot survive with bots (best played online with other people

Conclusion:

An epic campaign, gives you the Silent Hill experience! The best re-creation of the original Silent Hill. For the zombie spawning, they would spawn in the weirdest places, like right behind you and/or all around you. Didn't know if it was intentional or not. A+

Pros:

Amazing detail
Nice challenges
Custom weapons, music, and voices
New crescendos
EPIC OUTRO

Cons:

Finale was a bit too claustrophobic for my taste

Conclusion:

One of the best campaigns I've played so far. I believe you should play this at least once.

Pros:

Very good detail
Well-planned map design
Reminds me of Death Toll
Run-and-gun finale
Multiple color corrections

Cons:

Way too short
Finale was broken...?

Conclusion:

I don't know if this was just me, but when I got to the switch that turned on the power, a horde came, we took care of that, I hit the switch to the elevator, nothing happened, we pile into the elevator, the finale music starts, and the the credits roll. I don't know if the finale was broken or not.

Pros:

Great atmosphere
Liked the dialogue in the beginning
Good map design
Challenging finale
Lots of items and weapons

Cons:

Missing skybox texture in the 2nd map
Campaign's a bit too short
Bots derped out when the helicopter arrived
Mild lag
"Disturbed in the Suburbs" was ripped from Killing Floor

Conclusion:

Love this map!! A few tweaks could perfect it, but in any case a classic I will certainly play again and again.

Pros:

Good environment
Fair weapon placement
Nice crescendo events

Cons:

No dialogue
Invisible desks
Weak Finale
Some areas look like copy/paste of  official Left 4 Dead 2 levels

Conclusion:

Nice concept, but this needs improvement. I cannot wait for version 2 of this to come out.

Pros:

-good level design
-awesome gameplay
-very eerie

Cons:

-minor lag, but it was only for a minute

Conclusion:

Very very good campaign. Great for online.

Pros:

Cons:

-Too straight-forword

Conclusion:

Nothing special, but still fun to play!

Pros:

Cons:

-Lag
-Glitchey
-A bit boring

Conclusion:

Not the best map, but it has potential...

Pros:

-Good challenge
-Wide open space
-Relation to Portal
-Pleasing to look at

Cons:

-A little too wide open
-No GladOs voice :(
