Rescue On Fractalus! is a March 1984computer game created by Lucasfilm Games (later LucasArts Entertainment). It was originally released for the Atari 8-bit family and the Atari 5200 games console. It was also ported to other popular platforms of the day, such as the Apple II, ZX Spectrum (by Dalali Software Ltd), Amstrad CPC, Tandy Color Computer 3 and Commodore 64. The game was one of the first two products from the fledgling Lucasfilm Computer Division Games Group led by Peter Langston.
The game utilizes fractal technology to create the craggy mountains of an alien planet, where the visilibility was drastically reduced by the dense atmosphere. The player controls a fictional “Valkyrie” space fighter (converted for search and rescue duty) from a first-person view, attempting to land and pick up downed Ethercorps pilots. Some of these mountains hold anti-aircraft guns, which have to be avoided or destroyed. Due to the varied terrain, the direction finder has to be used to locate the pilots, whose visual beacons are often masked by mountain ridges.
