Haunt 'N Decay

You are haunting a secret facility. But the soldier you are controlling is being decayed if you stay at him for too long.
Controls: W, A, S, D to move.
Aim with mouse.

Left Click: Shoot
Right Click: Possess shot (you possess what you hit next).
The purple bar is your Decay bar and the red bar is your Health bar.

You lose if you could not possess another body, if your possessed body got decayed and if your health drops to zero.
Try to survive as long as you can.
