The mod features players on a new map, Operation Overdose, where players are picked randomly to play zombies or regular humans. Player zombies have melee attacks that they can use to turn the human team into zombies. Naturally the human players don't care for this whole "living dead" option and want to shoot the zombies down. However zombies have some advantages; they are highly resistant to bullets, moderately resistant to fire, explosions and melee attacks and completely immune to any poison attacks. Oh and critical hits? Not gonna do it to the undead.
The new update also adds some new weapons to the game including new shotguns, assault rifles and a new flamethrower.
