How long can you survive the endless zombie hoards. Power up with multiple weapons and try to take as many zombies with you as possible. Compare your high score with other to see whom will be the ultimate survivor.
Move around with WASD keys and point and shoot your gun by aiming with the mouse and left clicking. Hold the moust button to 'auto-fire'. Space will switch between weapons as you pick up the power-ups. Survive as long as you are able.
