Today Marvel Comics announced Uncanny X-Men: Days Of Future Past, a mobile game based on the dark future storyline from The Uncanny X-Men issues 141 and 142.
Yes, it is a mobile game, but it's a 2D side-scrolling mobile game from Glitchsoft, the folks behind He-Man: The Most Powerful Game in the Universe and Destructopus, so I am not afraid.
Uncanny X-Men: Days of Future Past is coming in May 2014 to iOS and Android devices.
