An interesting, if fairly short, shooter… you investigate a mysterious UFO, and stuff starts firing at you. It's a rail shooter, where you move with the arrow keys, and fire with space. The instructions also mention Shift to brake, but I'm not sure why you'd do that. Gameplay is pretty easy, most of the enemy ships have very slow and/or destructable shots.
The documentation to the game mentions in was coded in Turbo Pascal 6.0 and Assembler.
