You must save the Earth from annihilation by an evil threat.
Race against time with Mega Man X and his comrade, Zero. Together you must destroy the evil threat occupying Eurasia to prevent total destruction of the planet Earth. Just when you think that the chaos of the Reploid Wars has passed, a group of cyber-radicals has just broken into Eurasia's artificial gravity device. This has caused the space colony to spin out of control, on a collision course with Earth! Your objective is to collect the parts of the beam cannon, Codename Enigma; get it restarted; and deploy it within the next 24 hours.
