Evil Aliens that can perfectly mimick human beings are trying to get through the galaxy guarded post. You have a very sensitive detector that can identify aliens. As soon as the identity is confirmed (green circle = human, red “x” – alien), you have to eliminate Aliens with your powerful laser (press SPACE) and let humans go. There will be more and more people trying to get through as the game goes on – be very cautious!
Game Controls: SPACE – Use the laser
