Zombie Mod - Singleplayer mod for Command and Conquer Generals: Zero Hour This mod adds new campaigns to GLA, China and USA, humans fight against zombies that want eat your brain P: Zombies are not playable faction its only Campaign side (maby in next version Coop mode too)
And that's how i made most realistic mod/movie/anything about zombie apocalypse... In my world grass still grows :D just made a model - not biggy thing but adds really sweet effect in game.
For grass settings on 'high', a nuclear-powered version of the engine required ;)
