Players control the actions of several X-Men-related characters, most notably Logan, Nightcrawler and Iceman, as they uncover a plot to eradicate mutants. Sometimes, another X-Man will help the player's character battle. The Nintendo DS game features Magneto as a playable character, while the Game Boy Advance version features Colossus as a playable character. Many agree that Logan is the only useful character in the Game Boy Advance game, which allows players to cycle through characters at will, as he is the only one who can recover from damage.
