Survival Instinct
In Undead Invasion online, waves of undead rush in like a collapsing dam, forcing you to react fast or get overwhelmed.
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.
The Last Defense
- Move: WASD. Arrow Keys.
- Shoot: Mouse Click; Auto Fire.
- Reload: R.
- Pause: Esc.
