Zombie: The Hero provides several new features for both Humans and Zombies. This mode also introduces several new types of zombies.

New Mechanics


  • Humans can now be selected as a Hero/Heroine or sidekick, each with their own set of select-able powerful exclusive weapons.
  • Humans now has morale meter. Higher morale meter will increase the human's weapon damage. This meter can be increased by killing zombies, 10% boost for each zombie killed, with the maximum achievable boost of 230%. Being near other human players will give a bonus 5% attack boost for each player in the vicinity.


  • The zombies will revive instantly after death (but before doing their respective death animation) unless if they were killed by a headshot. They will revive in full health and regain any armor points they have before death.
  • In contrast to the human's Morale Bar, Zombies has the Rage Bar, which can be filled by taking damage or infecting humans (Heroes or Heroines gives a dramatic boost). Once it reaches its maximum, the zombie will evolve, increasing maximum health and armor.
  • Lesser zombies are now able to use their skills just like their Host counterparts does, but with less efficiency.

New Weapon
