Set a few years after RoboCop's invention, the story involves SAC-NORAD contracting Cyberdyne Systems on building Skynet. Cyberdyne used RoboCop's technology in creating Skynet. When activated, Skynet becomes self-aware and launches a war against mankind. In the future, Skynet sends several Terminators back to the past to cripple the Resistance. After destroying one of the Terminators, RoboCop proceeds to Delta City, where he confronts RoboCain. After RoboCain was destroyed, RoboCop battles his way to the OCP building, where he defeats all the Terminators. After defeating an ED-209 unit reprogrammed by the Terminators, RoboCop plugs himself into a console. Unbeknownst to him, RoboCop gave Skynet information it can use. This ends up with RoboCop falling into a trap. In the future, RoboCop assembles himself, where he battled in the Terminator-infested future and destroyed Skynet. The Mega Drive/Genesis version, which was the original lead development of the game and was programmed by Virgin Games USA making use of David Perry's Mega Drive/Genesis engine, is loosely based on the 1992 four-issue comic book mini-series of the same name.
