I rented the Xbox version of this game awhile back, which was also a great game as well. The graphics, controls and sounds are all excellent on the PSP. The only problem I ran into with both the console version and PSP is the camera. A few times, you may want to move the camera around a bit to check if you missed any items or there is something blocking your view.
Three different level challenges to choose from so if you win on the first level than you can go back and play a different level. Great fun for all. Hard to play at first but when you get use to it than you can't stop playing hour after hour. I don't recommend this for people who don't like fun games but if you do this is the game for you.
I liked the ability to switch between characters and utilize different fighting styles with different mutant powers. Load times between different chambers was slow and the layout was repetitive. I felt the camera angles were weak and didn't allow for proper viewing of fighting mechanics. It seemed a shame to waste all those cool fighting styles and not be able to view it properly. I think having a team of 4 x-men may work with multiple players but using a single player format left something to be desired. Oh well maybe I'll change my mind by the end of the game.
