Less than a year after Geist activated the Death Force, which decimated most of Jerra's population, he has kept himself busy by dismantling the Death Force machines one by one. Most of the remaining human population have fled to a remote haven run by a warlord named Krauser. Krauser is another MDS unit, MD-01, who has a technology that hides his mobile fortress from the Death Force.

A freak accident unleashes a demonic spirit within researcher John Stalker - transforming him into Saldo, a mythical cyber-beast fueled by hate and evil.

Geist (the main character) is MD-02, a Most Dangerous Soldier, genetically engineered to function as a killing machine, but every one of the MDS units went homicidally insane. As a result Geist was placed in suspended animation in a stasis pod orbiting the planet Jerra until it crashed several years later, awakening him and bringing him into another war on the planet.
