How Zombie Mod Mode Works

Zombie Mod infects one player at round start. Infected players spread the zombie virus on touch — humans must barricade chokepoints, conserve ammo, and survive until the round timer runs out. Zombies have high HP but no guns, relying on melee and numbers. Humans have limited ammo and reduced damage against zombies.

Zombie mod maps like zm_office, zm_dust2, and zm_army feature defensible positions, traps, and escape routes. Teamwork and knife-pushback mechanics are essential.
