This one is for the fans!
The gameplay is similar to X-Men Legends, but not as great. The game allows 1-4 players! However, if playing with others you really have to stick together or risk getting pulled away from a one-on-one attack.
Characters learn new abilities not by experience, but after a level has been completed. The horrible thing about that is sometimes you could become attached to a particular move and have it taken away by learning a new ability.
The game is rather short! The storyline is a bit confusing and disjointed, however, it's nice to fight familiar faces.
Overall, I highly recommend this game for the fans!
