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. This meter can be increased by killing zombies, which grants a 10% boost with the maximum achievable boost is 230%. Being near other survivors will give a bonus 5% attack boost for each player in the vicinity.


  • The zombies can revive themselves after 5 seconds of their death unless if they were killed by a headshot. However, after being revived, the Kevlar is set to 0.
  • In contrast to the human's Morale Bar, Zombies has the Anger 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.
