The PlayStation 3 and Xbox 360 versions are virtually identical, with no major differences. Both platforms include Colossus, Moon Knight, and five additional comic book missions. Activision released eight additional downloadable characters on the Xbox 360 via the Xbox Live Marketplace on April 26, 2007 in a set of packs: a Hero Pack, consisting of Cyclops, Nightcrawler, Hawkeye, and the Hulk, and a Villain Pack, which includes Magneto, Sabretooth, Venom, and a playable Doctor Doom. Both packs are also available in a bundle pack for 800 MSP, which adds 12 new achievements to the game. The Gold Edition was released for the Xbox 360 in May 2007 which includes the standard game bundled with all downloadable content. The Platinum Hits version was released for the Xbox 360 in September 2007. The set includes all the Gold Edition of the game and a bonus DVD. As of December 2009, the DLC was removed from the Xbox LIVE Marketplace by Activision, meaning the only way to play as the downloadable characters was to purchase the Gold Edition or the Platinum Hits version. The Xbox 360 Games on Demand version now bundles the full game with all previously downloadable content.
