A human getting trapped and infected by zombies

On every round players start out as humans, equip themselves with a few weapons and grenades, and head to the closest cover they find, knowing that one of them is infected with the T-Virus, and will suddenly turn into a vicious brain eating creature. Only little time after, the battle for survival begins. The first zombie has to infect as many humans as possible to cluster a numerous zombie horde and take over the world. Maps are set in the dark by default. Humans must use flashlights to light their way and spot any enemies. Zombies, on the other hand, have night vision but can only attack melee.

Gameplay Modes

Normal Infection

Multiple players enaging with the first zombie eventually stopping an infection

Players engaging with the first zombie and trying to kill it before it infects others

The round starts with one randomly selected player being infected with the T-Virus. It should infect human players and they infect more humans, this causes the infection to spread like wildfire. The goal is to infect every human.


The players are divided in two groups: Humans and Zombies. The humans are immune to the virus in this mode, the Zombies should kill all humans instead of infecting them.

Multiple Infection

The round starts with multiple humans infected instead of one, so the remaining players will have to act quickly in order to control the situation


The first zombie may turn into a Nemesis, a powerful fast-moving beast. It's goal is to kill the most number of human while sustaining the gunfire.


Everyone became a zombie except him. The survivor gets a machinegun with unlimited ammo and has to stop the never-ending army of undead

Plague Mode [Bonus]

A full armed Survivor and his soldiers are to face Nemesis and his zombie minions. The future of the world is in their hands.

Zombie Classes

From version 4.0 it is possible to create and add an unlimited number of zombie classes to the main mod. They can be made as separate plugins, by using the provided zombie class API, and easily distributed. By default, these zombie classes are included:
