Zombie Horde is a modification for Counter-Strike: Source which seeks to recreate the chaotic struggle of a group of humans attempting to defend themselves from a mindless onslaught of the undead. Or perhaps not so mindless, since not only are the humans in this scenario player-controlled, but so too are the zombies.
Just a few simple rule changes from normal Counter-Strike - the zombies get only a knife and regenerating health, up to four times that of the human players, and of course, immunity to headshots - and the use of Half-Life 2’s zombie models and a brand new game is born. A very fun one at that - it’s impressive how those small modifications generate the desperate and tense situations that are best summed up by these screenshots (1).
