Zombie3z.png Zombie Z is a game mode in Counter-Strike Online.


Every round evolving zombie and human ability! Get a virus score through battle, consume your score and make a variation. Every time you make a mutation, you gain random power and become more powerful.


  • Human: Survive zombie attacks or kill all zombies for the rest of the time.
  • Zombies: Infect all humans.


  • During battle, if you accumulate virus scores, your level will increase.
  • You can increase the number of weapons and zombie classes you can use depending on your level.

  • Smoke grenade will be converted into Vaccine Grenades, which will damage zombies within the hazy blue mist it creates upon detonation.
