Gorilla Warfare

You are a gorilla that has suffered various genetic experiments, and now that you have managed to escape you want vengeance. It is up to you to reach the lab control center and free the rest of prisoners. Move around the screen with 'WASD', change weapon with '1,2,3 or 4' and shoot with the mouse. Sometimes your movement will be limited, you will only be able to pass when an arrow appears. You will be able to protect yourself from your enemies by hiding behind some boxes or corners. While you are hidden you won't be able to shoot.
