After a few delays that snagged the release for two weeks, today Activision unveiled new Marvel: Ultimate Alliance downloadable content over Xbox Live Marketplace. Building on an already-robust arsenal of characters, eight new playable heroes and villains, including The Incredible Hulk, Magneto, Cyclops, and Venom, are now available to expand on last fall's hit. Every character has their own skins, signature powers, dialogue, and most importantly for 360 addicts, achievement points.
Activision is releasing packs individually for 500 Microsoft points ($6.25 USD), or combined for 800 points ($10.00 USD).
