At least 15 years after Andrew Scott's death, former UniSol Luc Deveraux has been reverted to normal via genetic procedures. He currently works as a technical expert for the U.S. government with his new partner Maggie, who has been through countless hours of combat training with him. They worked to refine and perfect the UniSol Program in an effort to make a new, stronger breed of soldiers that are more sophisticated and intelligent to reduce the use of normal, human soldiers in the battlefield. All of the new UniSols, known as UniSols 2500, which are faster and stronger than the original UniSols, are connected via neural implants through a sentient artificially intelligent computer system called S.E.T.H. (Self-Evolving Thought Helix).

When S.E.T.H. discovers that the UniSol Program is scheduled to be shut down because of budget cuts, he finds this to be a disgrace and decides to take action by formulating a plot to overthrow mankind and take over the world with his own massive army of UniSols. The next day, S.E.T.H. unleashes a platoon of UniSols, led by the musclebound Romeo, in a hostile takeover of the UniSol building, resulting in the deaths of many occupants, including Dr. Dylan Cotner, who was responsible for reverting Luc back to normal. As such, Luc, Maggie, and the others are forced to evacuate. With the help of a rogue cyberpunk named Squid, S.E.T.H. is able to put himself into a UniSol body superior to the others. In the meantime, Maggie noticed that Luc's daughter Hillary Deveraux has suffered brain swelling after almost being attacked by Romeo, and Maggie takes her to the local hospital.
