Mega Man 9: Endless Attack Mode(2008)

Endless Attack Mode will be added to the Game Menu. Try to get as far as you can in a stage without end. (Distance measured in "screens.") Mega Man must make his way through an "endless" version of Dr. Wily's fortress, facing difficult enemies, challenging rooms, and all eight of the Robot Masters. Players start out with no extra lives, parts or energy tanks, but have all of the special weapons. There are 42 levels of about 3 screens each, including boss areas, and the game randomly determines how these are generated.
