Unsurprisingly, Marvel is using its mobile games to push some tie-in content, and thus promotion, for its just released movie Captain America: Civil War.
Here's a roundup on which apps were updated and the content that it brings:
If you're booting up MARVEL Future Fight (iTunes/Android), you'll be able to join the Civil War event and play with some new heroes and uniforms. You can also fight Thanos and his Black Order generals Supergiant and Ebony Maw as world bosses.
In Marvel: Avengers Alliance 2 (iTunes/Android) you'll find plenty of improvements to the game on top of new heroes such as Captain America and Iron Man as they are represented in the movie. Some new missions will also await you in Spec Op 2: Captain America: Civil War.
