Mega Man Mushroom Kingdom is a fan-made modification of the 1987 action-platform Nintendo Entertainment System video game Mega Man. Dr. Wily eventually concedes that Mega Man may be too powerful for his evil cyborgs. Dr. Wily contacts Bowser, a well-known villager, in an effort to obtain the finest blue bomber. Dr. Wily and Bowser unleash their new destructive constructs on the Mushroom Kingdom after combining their forces. Mega Man determines to travel to the Mushroom Kingdom to stop Wily once again after learning of his latest scheme. Now, Mega Man finds himself in a strange new universe full of unfamiliar obstacles and locations. Mega Man resumes his fearless assault on Super Mario's old base in order to defeat these new foes. Mega Man must defeat King Koopa and his forces in the Mushroom Kingdom. This is Super Mario's World, and he is delighted to assist Mega Man by enhancing his jumping ability and providing him with some of his old outfits.
