Its just not that good!
To be honest i was really disappointed when the game first started, i was all hyped up thinking that you got to choose your favourite character and you kick a** through out the game with them, powering their levels up and gaining new moves and as the game progresses you get to harness their awesome mutant powers. Now thats not what i got, i got 4 characters on one screen, hardly any story line to what has happened and then i have to fight my way through and handle one whole team. This is definitely not what i wanted or expected, i still thought maybe they put you in this testing screen just to see how all the characters move and perform their fighting skills but as the game continued i was really upset to find that things stayed that way.
In all fairness the graphics are good, the characters are easy to handle, the gameplay isn't bad and the sound is actually pretty good but it still disappoints me that every time i look in my games collection i see a game that i don't wanna play and i know for a fact it will sit there never to be played again.
