I love love this game! Ultimate Alliance is the perfect game. If you ever played the Xmen game for regular Xbox, then this may look familar - but it's still great anyway! You can pick just about any character to play (some are locked to begin with though) and basically you run through the rooms with three other players, which can either be computer players or other co-op players, defeating enemies as you go, gaining experience to level and get new special moves! Then usually you get to a boss, who sometimes have some kind of trick to figure out. There's also trivia and really cool comics and scenes. It's not only fun to play, if you're a Marvel fan, then it's fun to wathc as well! Overall, the game and graphics are awesome - and has GREAT replay value! I highly recommend it!
