If your a zombie survival fan this mods pretty good

Zombie Master is a multiplayer Half-Life 2 modification, centred around a zombie-apocalypse, which throws all but one player in the shoes of human survivors. Pitched against a relentless tide of rotting flesh, they must scavenge for weaponry and equipment just to stay alive. But that one player, chosen randomly at the beginning of the round, is not bound by mortal restraints.
To speak his name is to invite the wrath of hell - but most call him the 'Zombie Master'. He is nigh omnipotent. His invisible hand controls the legions of undead like puppets on strings; slowly closing the net on the humans while they run to and fro like rats in a maze.

So the zombie master has a flycam and he controls where zombies spawn and what types of zombies, as well as setting off the occasional boobytrap, and the humans also have there own objectives - so when your up against a good zombie master it can be pretty challenging




its still in beta stages but ive had alot of fun with it and quite a few people play it
