Marvel: Ultimate Alliance 2 - Fusion is the sequel to the 2006 action-RPG Marvel: Ultimate Alliance, coming in autumn 2009 from Activision and developer Vicarious Visions. The story starts with Secret War: Nick Fury's invasion of Latveria is used as a jumping off point, and the rest of the story is derived from the consequences of those actions. The game's main innovation is the introduction of fusions (team-ups) between each of the heroes. Ever wonder how Spider-Man and Captain America would team-up?
