Inspired by the Alien franchise In this game you have to collect all of the collectables and run away from the aliens. You have a motion tracker that tells you how close the aliens are to you. Use W/A/S/D or arrow keys to move, and use arrow keys to look around. Lower resolution = more detailed higher resolution = less detailed.
