All that is know as of now is it is a game that has us the players controlling a new mutant recruit. We also will get to make all the choices for this character. This leads me to believe that you can go either good or bad all Fable-style with the character. All of which will take place in an original story written by Mike Carey (Marvel X-Men: Legacy).
That is it. Most of that doesn't even come from the below video. I guess we'll hear more after the panel for the game which takes place this Saturday (10/9) at 10:45 am EST. Hopefully then we will have more then what I just listed here. Hopefully.
