The game features a ‘roguelike’ system for random generation of hazards, AI locations and items; with only one life. The game has no HUD, or scoring systems. It also has multiple endings that are based on your actions. Permadeath will occur upon failure. Players are equipped with a weapon called “CAT” (“Cosmonaut Assistance Tool”) that can be upgraded with floppy disks, which directly affect how the weapon reacts.
