Gamers play and develop their own comic-book mutant heroes and villains in X-Men: Destiny. Set in the Marvel universe and featuring familiar friends and foes from Professor Xavier's School for Gifted Youngsters, the game focuses on three original characters -- teenagers whose mutant superpowers are just beginning to manifest. Each playable character has a basic mutant special ability, which players gradually custom-enhance as they earn upgrades throughout the adventure. Although the looks and personalities of the super-powered teens are predetermined in the backstory, their destinies are to be decided by the player -- one choice at a time. Players lead their characters through a branching plotline, which ultimately has the young mutant choosing between the X-Men and Magneto's Brotherhood. Set in a future San Francisco, torn apart by a war between mutants and regular humans, the game's story features Cyclops, Wolverine, and several other well-known mutants and monsters from X-Men comics and movies. Playable heroes develop relationships with these established characters, depending on the actions they choose. X-Men: Destiny was developed by Silicon Knights, creator of original, story-driven action games including Eternal Darkness and Too Human.
