allowed players to freely switch characters. The final product mimics isometric dungeon crawling video games. Raven designed gameplay with strategy in mind; each character's abilities allow different interactions with the environment and other characters. For example, a physically strong character like Colossus can break walls but is unable to reach certain areas that require the ability to fly, and Iceman is able to freeze enemies so that other characters can easily defeat them. Staff hoped that the differences would force players to switch characters regularly during missions. Extraction points, specific locations that players can switch characters, were added to allow players to continue without a game over in the event one or more team member was defeated. Raven included flash back missions as an homage to the franchise and based some on specific comic book issues. Originally a single-player game, Raven eventually incorporated simultaneous co-operative gameplay. The developers chose to not create an online multi-player mode, stating that the gameplay was "designed around localized encounters". The game's story was penned by a group of former Marvel writers known as Man of Action, consisting of Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle, with Stan Lee consulting. Man of Action chose the character Magma as their lead because she was an "appropriately blank slate as a character". Man of Action also stated that the script for X-Men Legends was in excess of five hundred pages. The writers created a story that would allow for players to change their active team throughout the game and not affect the overall flow of the story. The game's voice cast consists largely of television and film stars as well as veteran voice actors. Patrick Stewart reprised his role as Professor Xavier from the X-Men films, while Tony Jay voiced Magneto. Ed Asner lent his voice as Healer, a Morlock shaman. Lou Diamond Phillips voiced Forge, a Native American mutant whose power grants him intuitive talent for inventing mechanical devices. Danica McKellar voiced Jubilee, a young mutant who generates plasmoids from her fingertips. Veteran voice actors Steven Blum, Grey DeLisle, Dee Bradley Baker, Robin Atkin Downes and Dorian Harewood also lent voices as Wolverine, Mystique, Nightcrawler, Cyclops and Shadow King, respectively. Music for the game was composed by Rik Schaffer of the Los Angeles-based Womb Music. Characters were selected from different time lines in the X-Men universe. Art lead Brian Pelletier said that they
