Plot summary
Silent protagonist Mr. Shifty, in radio contact with his superior Nyx, breaches Olympus Tower, the offices of StoneCorp. They aim to steal a dangerous weapon called the "mega-plutonium", to prevent its use for nefarious purposes by the evil Chairman Stone. Shifty infiltrates the building's lower floors and locates the mega-plutonium, but it is a decoy and a bomb. Nyx and Shifty, undaunted, decide to continue by killing Stone, who contacts Shifty by radio. Stone is impressed by Shift's abilities and offers him a job, but Shifty ignores him. At the end of the chapter, Stone sedates Shifty with noxious gas in the elevator, saying Shifty should have accepted his offer.
Shifty awakes deep underground in a cell filled with a shift blocker, but punches through the wall to freedom. He fights his way to a computer terminal, where he re-establishes radio contact with Nyx, who guides him to the surface. There, he encounters Stone, who seems to die in a large explosion.
Nyx at first intends to extract Shifty, but they encounter Stone again soon after. Nyx, shocked, orders Shifty to kill him, but Stone disappears. He reveals that he has studied Shifty and used the real mega-plutonium as a power source for a machine that can teleport anything everywhere. Shifty battles through the many obstacles and guards that Stone shifts in his way, finally destroying the machine's core. This causes it to go haywire, shifting objects randomly, before it explodes and dies. Shifty enters Stone's office at the top of the tower, dodges the hail of gunfire from Stone's twin tommy guns, and kills him.
