These are the impressions that had me returning this game two hours after rental. It could be amazing after the two hour mark. But there were enough problems to turn me away.
This game is mad ugly, and really derivative of God of War in the combat, at least in the early parts of the game. Maybe it changes up later? I don't know since I've already shoved this thing back in the Redbox.
Super stilted dialogue/acting. The dialogue trees are unintuitive, and act as specific examples of pretty shitty UI, as well as somewhat offensive shades of yellow.
But, nothings really broken. If you're really into the Xmen, maybe you'll get something from it. Just don't pay attention to the walk cycles of the Purifier character (forgot his name already).
In fact, don't pay attention to the game, and you'll do fine. Walk on by.
