Pros:

Actual Port of the campaign.
Most of the textures work, and so do the models.
Has some challenge to it.

Cons:

Some maps are really short (Like the apartments)
All of the items are rigged. Everything spawns the same with no changes.
Item caches give too much.
Finale lacks instructions (We screwed up twice not knowing what to do.)
Not many changes in the port. Nothing new or special.
The sky keeps flickering to black (I tried mounting Hl2 again to see if it would fix, to no avail)
Lack of balancing. It's tilted too much to the survivors, they get tier two weapons at the start.
Ending continues to play game play sounds (No finale music)

Conclusion:

Upon playing the map, it has cons everywhere that make it a grudge to even play. It needs some improvement and better map blending. At least it is playable.

Pros:

The custom music stays true to the original themes.
The custom weapons are great ports of models from tf2, which actually work nicely.
The level design is work I have not seen before, and it is well done.
Transitions from level to level are smooth, and not just simple cuts from place to place.
The function of the map and use of the ai director is tested to the limits, and works very well.
3d Skyboxing looks well done
Use of lighting is okay, considering few places have lights, but that matches the apocalypse theme
Fitting dialouge that matches every area (The steam one was very neat)

Cons:

There is a bug at the caboose rescue were the survivors do not show. (Normally they do)
Survival could use more places. The finale area is just one, and there are other places it would work.
There are some spots at the finale which are way to easy. (Standing on the shelf in the left building)

Conclusion:

Overall; this is one of the best survival maps I have played in a good while. Everything is detailed and it looks like the work was well worth it. The custom weapons and music add to the feel of the campaign and everything just blends and transitions smoothly. This campaign is worth the download and has great replay value.
I hope to see more submissions like this which really define Left 4 Dead custom content.

Pros:

Makes you feel very attached to the game
Fitting music for most situations

Cons:

Sound quality is a  bit poor

Conclusion:

Needs some tweaking

Pros:

Works Perfectly

Cons:

Stored ammo needs to be set at 16, not 30. 30 is just too op.

Conclusion:

Works great. Would not reccomend this on levels that are easy to begin with.

Pros:

+ Great theme in General. Very new and fresh.
+ The water indeed made me thirsty.
+ Well thought out moments of hordes and tanks. Actually gave me a challenge once playing

Cons:

- Finale is waaaay to easy. Make it go out with a BANG, not a cut-scene.
-AI is sometimes stupid and we have to leave them behind cause they know not what to do.

Conclusion:

Great Campaign. A very fun time while playing with friends. But the cons are really annoying and could easily be fixed because this really breaks the fun whilst playing.

Pros:

+Works on online!
+ No Crashing anymore!

Cons:

- The Cons selection exists here.

Conclusion:

Awesome work! This is something I've always wanted to work, yet It did not. Now I can use this mod.

Pros:

Good campaign. Fun to play.

Cons:

-Alters sounds, models, skins, etc. which cause errors and sound clip noises. And the bullet dropping noise is very annoying as hell.
-Some of the map makes no sense in construction. I'm not sure if this is resident evil's fault or yours, but these need to be fixed.

Conclusion:

Remove the custom content and it would get a 10 from me. The custom content is just annoying and bugs the hell out of me, and somethimes makes the campaign nearly unplayable.

Pros:

+ The Ads are more practical and realistic.

Cons:

- The Beck's Beer ad contains nudity. I know this is a small issue, but it kind of bugs me. Also advertisers never use this much nudity in ads.
- Some of the images are streched or just wallpapers.

Conclusion:

This is great! Just touch up on the cons and it will be flawless.

Pros:

Very puzzling campaign. Makes you work as a team, yet also figure out puzzles.
Great use of gascans. Makes you actually need to save them to survive.
The need to remember codes so it's vital players do. (Mainly at the finale)
Simple design, very effective. Very clean looks.

Cons:

On map 2, there is a shortcut to skip the alarm. It has the metal detectors, exploding floor water, and the 50 cal. Players can hug the fence and jump down to skip the panic event.
     - Along that, if the alarm is activated after the button is pressed, it never stops flooding zombies
Zombies require more areas to flood and sneak attack. (Meaning zombies are too easy to kill. Predictable basically.)

Conclusion:

I'll be honest, this map is fun in every way possible. It confused me on my first play-through but It was a ball. The bugs could use some fixing, but they're very minor bugs anyway.

Pros:

Bots continue to play and even rescue from a closet once dead.
Bots now use melee weapons to actually help out in the fight.
Bots don't wait for 3 seconds to realize a hunter is destroying you. (In most cases enough to incap)

Cons:

Can be used to farm achievements for completing campaigns. (I think) I won't deduct points for that though, but it's something to keep an eye on.

Conclusion:

Everything in this mod fixes single player issues. More could be added and it could even be used for an Xbox360 mutation! (Who knows?)
I love everything in this mod. I will from now on consider you a god.

Pros:

New Idea for Mutation. I LOVE it!

Cons:

..I'll have to get back to you on that one.

Conclusion:

Overall good Idea for a mutation. Send it in to valve!
Ideas:
Don't give them more ammo. Make it so that the tier weapons are different. Like players start off with higher tier weapons. Perhaps Ak47, and Spas-12 and deagle to start off with. Then they get scars, auto shotguns, Chainsaws, M60s, and so forth.

Pros:

Gun works very well on anims
No clipping, or anything messed up.

Cons:

The Magazine is Flat in First Person

Conclusion:

This works fine, just needs to fix the Flattened Magazine.

Pros:

Ammo changes have been made. Some are realistic.

Cons:

The Scar-H will actually hold 26 bullets. The M16 22, and the AK47 20.
The Chrome Shotgun has not been altered.
Autoshotguns actually hold 4-5 bullets. 6 and 7 are incorrect values.
Pistols have 8 bullets. They should have the value for dual pistols to be 16.

Conclusion:

There is much tweaking to be done to this mod. Most of the values are incorrect, and seem very unrealistic.

On a side note: Were did you get the mod to make the scar fully automatic?

Pros:

Replaces old SMG

Cons:

The fingers are a little off with using Arby's animations

Conclusion:

I'm kind of the guy who likes perfection when it comes to new weapons. This needs some tweaking.

Pros:

Not bad looking. Kind of looks Badass.

Cons:

Simple Paste of texture.

Conclusion:

You can put a little more effort into the gun. I'll give you a 50 since I kind of like it.

Pros:

It's Hellsing
Large Guns
Very accurate

Cons:

Textures look too plactic
Needs new animations to fit the gun
Reload sounds sound too.. metal like, like as if you were picking up metal.

Conclusion:

Has potential, I'd download this is it could get more fixes.

Pros:

Fairly simple. Evade tanks and try to survive.

Cons:

..What cons?

Conclusion:

Overall great maps. I will DL all of them.

Pros:

Not been done before on the website (~!FIRSHTIEZ!~)
New and cleaner textures

Cons:

The Gauge on the Oxygen is a bit unrealistic
The Gas Can's Preem logo is slightly off centered. I suggest centering it so it's on one side. And the logo is a tad bit smaller.

Conclusion:

It's new, and clean. But Not what I'd be looking for.

Pros:

Cute :3
Adds more of a "Pallete Cleanser" when playing such a gore-infested game.

Cons:

Erm... Wat.

Conclusion:

This is great! It's awesome! I would like to see more like this!

Pros:

Works
Much more realistic

Cons:

The sounds swap around (M16 sounds like Scar-H, Scar-H sounds like M16)
Sometimes when you pick up an M16, then an SMG, you're hands go off the screen in first person. Same with Scar-H.
Sometimes there are no First person arms, or no Image on the Gui

Conclusion:

It's Ok, Just has quite a lot of bugs.

Pros:

Brings Back Good Memories of Mario Kart

You have to use the more Open area Strategy rather than the usual enclosed strategy.

Each corner has it's own weapons

Cons:

There would be few places to spawn as SI in scavenge.

Bots take Over Convoluted ways just to get to you.

It Could use a Plain Color texture rather than the Grid texture like the good ol' days.

Conclusion:

It really is a great map, just has some bugs. Good work for you're first map.

PS: Could you happen to help me with my Survival Map? I can't seem to get any zombies to spawn. PM me and i'll send you my skype.

Pros:

New, cool look that fits the tank.
Not pink, colored like skin.
More scary when you encounter

Cons:

The "shredding" Creeps me out a bit, But I can manage.
MUCH harder to see in Campaigns like Hard Rain.

Conclusion:

I like it, but it just scares the sheep out of me.

Pros:

Nice timing to make a skin in 10 minutes.

Cons:

The Yellow and White look does not seem so... Civilian-like.

Conclusion:

The gun is alright, but I'd suggest using a yellow and white color scheme because not many people carry that kind of weapon.

Pros:

Huge Map.
Lots of fun things to do.
Weed!
TON of places to hold out.

Cons:

Too much open space.
The horrors of the Attic.
The F U Thing gets abusive.

Conclusion:

I'd sav this is a more interactive map than a survival map, but add more things on the floor to mess around with. Legos Idk... something.

Pros:

Good O'L Mario Style
Good for people who Lag on L4D2

Cons:

Zombies don't die after falling.

Conclusion:

Fun map to play one once in a while.
