Undead Invasion

Undead Invasion

Undead Invasion is a fast-paced 3D FPS survival game where players fight endless zombie waves, upgrade weapons, and survive the undead outbreak online.

Undead Invasion: Survival Instinct

Undead Invasion is a browser-based FPS survival game set in a relentless zombie outbreak. In Undead Invasion online, waves of undead rush in like a collapsing dam, forcing the player to react fast or get overwhelmed. 

The experience feels raw and tense, like a stripped-down Zombie Outbreakwith light UI tower defense elements. A few rounds in, the pressure becomes addictive rather than stressful.

The Zombie Onslaught

  • Spawn into a 3D battlefield surrounded by undead
  • Move constantly to avoid being cornered by zombie waves
  • Shoot incoming enemies and manage the limited space carefully
  • Survive each wave as enemies grow faster and tougher
  • Earn rewards to improve firepower and endurance
  • Longer survival feels like holding a line in a losing war, but that’s the thrill

Dead World: The Last Defense

  • Move = WASD. Arrow Keys
  • Shoot -> Mouse Click; Auto Fire
  • Reload = R
  • Pause = Esc
