Zombie Survival is a modification of Counter-Strike Source, which is very customisable, even enabling you to add new and custom guns for the humans to earn! It introduces a zombie game-mode, where the humans have to survive the round against the zombies, who are made up of their dead team-mates. Humans earn better guns by killing zombies. Zombies can choose from 5 classes, including the explosive chem-zombie, to the strong poison zombie.
These are some of the Zombie skins that are included in the release.
This mod sucks. Seriously!. The skins are aweful, and there nothing different but skins and some physics. -.-
