Marvel Ultimate Alliance is back, with 24 characters to choose from, tightened controls, and Fusion powers. Fusion powers are available to all the characters in the game, and are done by linking up the powers of any two heroes. Fusion powers are a big part of what the game is being sold on; well that and a mix of two of Marvel's most popular storylines. Secret Wars, and Civil War. Will you choose to fight by Iron Man, or will you stand with Captain America against hero registration. Those are your choices; let's see how it plays out.
