Pros:

Colors! :D :D :D
Makes the game better in general.
Zombies don't look like goth teenagers anymore! :D

Cons:

It seems like they don't work on L4D1 maps, but that might just be lighting.
Hmmmm....... I guess there is nothing else.

Conclusion:

Very nice mod! I am going to use it for now on. Download this if you haven't.

Pros:

Really nice map to survive in
Lots of space to run around
Really fun

Cons:

Not enough weapons
Needs more special tier weapons (G-launchers and M60s)
Buggy skybox
Feels like a beta of a map
Can't find pipebombs

Conclusion:

Ehh, if you added more weapons that are dropped everywhere, added special tier weapons, and added some pipebombs, this map would be awesome.

Pros:

High quality model
Neat animations
Makes the magnum feel 10x stronger

Cons:

What's a con? Cone? Can? KHAN? KHAAAAAAAAAN!

Conclusion:

Jolly good mod!

Pros:

Battlefield 3 sounds!
Makes weapons feel more powerful.
Sweet Quality.
Gives me a reason to use dual pistols. :D

Cons:

G-launcher explosion is too quiet
I hear a weird beep whenever I pull out the Uzi
The echoing doesn't fit

Conclusion:

It's a great mod, you barely notice the cons anyway, if the echoing is less, "echo-ish" and the G-launcher explosion were louder, I'd give it a 10/10!
