As the humans mainly had advantage over zombies in its predecessor, the developers (Nexon) decided that in this new mode will bring new weapons and skills in order to increase the "thrill" in fighting zombies, as well as powerups for zombies to aid in their fighting capabilities.

Kills indicator

Keep in mind : Humans' blood is the source of the zombie's strength. Do not allow them to massacre your comrades or they will evolve to powerful zombies.

A host zombie can evolve into an origin zombie by infecting 3 human players in a single round. They will gain the same special abilities that the origin zombie possesses. Their maximum health points is also boosted to 7000HP.

If the origin zombie manages to accumulate its infection to a total of 5 kills in a single round, it will evolve into a prime zombie which has a very high lifespan and armor (14000HP).
