The hum of the energy generator is the only thing standing between your squad and total annihilation. When the undead swarm breaches the perimeter, every split-second decision dictates who lives and who becomes lunch in Zombie Protocol. This dynamic, real-time strategy thriller throws you straight into the apocalyptic deep end.

Every wave brings new threats—no two survival runs ever feel the same.

Most players fail before reaching wave 15—will your squad be the exception?
