Zombies were created when the Rex Research Institute were experimenting on living things. They later escaped from the laboratory and started infecting other humans. They were first seen in Abyss, the later in other maps. During the chapter Chaos, they managed to escape to the surface and infected the people in Habana Vieja. Dr. A was seen being chased by a zombie after the Rex Virus Incident.
Differences between Origin and Host Zombies
A common misconception  among players are the [Origin] and [Host] zombies. At the start of each round, either one or two players, depending on the amount of players joined, would be chosen as the zombies.They would be [ORIGIN] zombies NOT [Host] zombies. Only the Singapore/Malaysia and Indonesia region is known to make such an error.
- [Origin] Zombies – They are the players chosen to be zombies at the start of each round. They used to be scientists, and were gradually infected with the Rex Virus.
- [Host] Zombies – They are the devolution of the [Origin] Zombies. These zombies are similar to the Origin Zombies except that they used to be the humans  who had been infected by another zombie.
After 20 seconds of the round, one or two of the players are chosen to become an Origin zombie (This depends on the number of players). The Origin zombie must infect all of the other humans by its claw. Infected human will turn into host zombies and must attack other humans. Zombies are considered the winner of the round if all humans are infected. In this mode zombies can't envolve and no HP regeneration.
New types of zombies have been released in this mode; Light zombie, Heavy zombie, Psycho zombie and Voodoo zombie.They will also gradually start to infect the surviving humans. They have new abilities that can regenerate their HP and evolute with the blood of humans. The origin can now execute their abilities whereas the host can't.
New playable characters are released: Hero (Andrey) and Kate (Heroine). These characters each hold exclusive weapons that only they can use and are meant to kill zombies( SVDEX for Andre and Quadbarreled Shotgun for Kate). The zombies are able to revive unless a headshot is inflicted upon them. However, each zombie killed will increase surviving humans morale , thus increasing their strength by 10%. This increment applies to all humans. New zombies are also released: Deimos and Ganymede.
