Half-Life 2 - Zombie Master Mod v1.1.2

Create and command your own undead horde
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.
