In the future, human soldiers of John Connor's resistance force against the machines are fighting a losing war against Skynet and its robot forces. Discovering that one of the foundation technologies for Skynet is the cybernetics technology used in the creation of cyborg police officer RoboCop, Flo, a resistance soldier, is sent back in time to destroy RoboCop and stop Skynet from being built. However Skynet learns of the time travel attempt and sends Terminators to stop Flo.

RoboCop soon meets up with Flo and must engage in battle against Terminators, the forces of OCP and several obstacles. Upon discovering one of the Terminators has infiltrated the OCP building, RoboCop plugs himself into a console to reprogram the security, only to fall into a trap and be digitized. After his body is disassembled and used for building Skynet, RoboCop watches Skynet come to power before using his digitized mind to seize control of an abandoned robotics factory, rebuild himself, and begin to destroy Skynet in the future. He successfully destroys the Skynet CPU and prevails, and turns his sights to helping humanity rebuild from the devastation.
