Shortly after teen Alison Crestmere begins to exhibit her mutant powers, she's hunted through the streets of New York City by anti-mutant troops and The Brotherhood. Rescued by the X-Men, Alison is taken to Professor Charles Xavier's School for the Gifted where she begins her quest to learn control over her lava-based powers.

X-Men: Legends is a role-playing game set in the Marvel Universe. Offering single and multiplayer support, Legends tells the broad story of the war between mutants and humankind and the conflict between the X-Men and The Brotherhood, against the personal story of Alison and the role she plays.

Controlling a party of four X-Men, picked from a roster that grows to 15 mutants, players take on armed guards, evil mutants, and killer Sentinels. Mutant powers grow stronger as the X-Men level up, but so do the challenges: securing an aircraft carrier, preventing a nuclear power plant meltdown and more.
