VR 3D Zombie Attack

The zombies can attack from any direction. Gaze at the zombies to fire. No controller required. A swivel chair is recommended. When you run out of ammo, look up and gaze at the AMMO to reload your weapon. You must not be bitten. You will turn to a zombie. It only takes one bite. Each level, the zombies get stronger but you get more ammo before needing to reload.
