Two of Marvel's biggest summer films, Captain America: The Winter Soldier and Guardians of the Galaxy, will be coming to Facebook, iOS and Android in the form of extra content for Marvel: Avengers Alliance. MTV reports that the game, in which players fight teams of Marvel villains in turn-based battles, will feature Winter Solider missions that "run parallel" to the film's plot later this month.
Details regarding the Guardians of the Galaxy content were not given, except that it would introduce the members of the team one at a time, instead of all at once. The Guardians movie doesn't hit theaters until August 1, so there's plenty of time for introductions.
2014 movie tie-ins aren't the only content planned for M:AA - Taskmaster will also be introduced as a playable character in an upcoming update. At this rate, we'll have every Marvel character in the game sometime shortly after the sun explodes.
