Pros:

Highly Visible Survivors
Highly Visible Special Infected
Dead survivors tend to stand or "pray" while dead, is hilarious and tends to make nice screen shots.

Cons:

People complaining about it
The colors get annoying at times

Conclusion:

Personally I love this mod. Yea you have people complaining about "cheating" cause your using a mod. Which for anyone on this site to complain about a mod is just hypocritical in the first place but whatever. 

Pros:

Better music for the tanks

Cons:

There's a bit of a lag before the music starts playing, but I'm sure that's because of the song itself.

Conclusion:

Its exactly what it says it is, Castlevania boss music for the tanks. Never have I felt the urge to attack a tank with a melee weapon every time I see one now. Good job.
