Marvel has partnered with developer Glitchsoft to develop a mobile game based on the seminal 1981 X-Men storyline "Days of Future Past."

Appearing in The Uncanny X-Men #141-142, the story by Chris Claremont and John Byrne depicts a timeline created by the X-Men’s failure to prevent the Brotherhood of Evil Mutants from assassinating a U.S. senator. In that alternate future, the giant robotic Sentinels have become the de facto rulers of the United States, where mutants are hunted down and placed in internment camps. To prevent that dystopian world from coming to pass, an adult Kate Pryde transfers her mind into her younger self in an effort to stop the event that triggers the anti-mutant hysteria.

The arc serves as the inspiration for the upcoming Fox film X-Men: Days of Future Past.

The side-scrolling 2D game, called Uncanny X-Men: Days of Future Past, is described by Glitchsoft as "a fast-paced, rewarding, and combat-focused experience." it will debut in May.
