Mega Man X6

Mission Critical... Zero is missing... Search and Rescue! Three weeks have passed since Earth nearly collided with the space colony Eurasia. The disaster was averted by Zero's heroics. Now stories of rampaging Reploids are surfacing on the battered planet. It's up to Mega Man X to investigate these mysteries, but it won't be easy. Mega Man X must fight his way through a maze of levels, rescuing Reploids along the way. You'll return to battle again and again with the new Nightmare system that randomly generates level maps, enemies and endings. Mega Man X is back and now it's personal!
