RoboCop 2 is based on the 1990 film of the same name, in which a Detroit cyborg cop known as RoboCop must stop drug distributor Cain from spreading a new drug known as Nuke. The Game Boy and Nintendo Entertainment System (NES) versions are primarily shoot 'em up games. They differ from the Amiga, GX4000 and Commodore 64 versions, which also differ from each other. In addition to side-scrolling platform levels, the Amiga and ZX Spectrum versions include other levels consisting of first-person shooting galleries – an aspect from the original RoboCop game – and a puzzle game in which the player must help RoboCop remember his memories by arranging certain electronic chips.
