Their objective is to stop the villain Magneto from wreaking havoc on human civilization.
They must fight through an army of hundreds of Sentinels and supervillains such as Pyro,
Blob, Wendigo, Nimrod, The White Queen, Juggernaut, and Mystique, who was also a boss enemy
in the game, although she simply took the form of Magneto and attacked players with punches and kicks.
Later, Magneto kidnaps Professor X and Kitty Pryde, prompting the heroes to go on a rescue
mission. The heroes fight their way to Island M and ultimately to Magneto's base on Asteroid
M where the final battle with the Master of Magnetism takes place.
