Uridium was later released for the Nintendo Entertainment System in 1990. Mindscape purchased a license to release a game based on the film The Last Starfighter. Rather than program a new game, however, Mindscape decided to take an easier route by recycling an older, relatively obscure game. The title screen, sprites, and soundtrack were modified, but the levels and gameplay were identical.
