Demon Attack is a video game published by Imagic for several home console systems, including the Atari 2600, Intellivision, Odyssey, Atari 8-bit, Commodore VIC-20, Commodore 64, PC (booter), TRS-80 and TRS-80 Color Computer. There was also a port to the TI-99/4A titled Super Demon Attack. Demon Attack was programmed by Rob Fulop. Marooned on the ice planet Krybor, the player uses a laser cannon to destroy legions of demons that attack from above. Visually, the demons appear in waves similar to other space-themed shooters, but individually combine from the sides of the screen to the area above the player's cannon. Each wave introduces new weapons with which the demons attack, such as long streaming lasers and laser clusters. Starting in Wave 5, demons also divide into two smaller, bird-like creatures that eventually attempt descent onto the player's cannon.
