After destroying Omega Bomb Man, Omega gets yet another alert from Command that another Omega Master is on the loose. When he arrives in an area of Sythisaville that is still being built, he runs into Omega Fire Man. Omega Fire Man is also controlled by the strange virus...However, after every Omega Master he fights, Omega is one step closer to finding the truth. Same controls, you know the drill.
