DeNA and Marvel Entertainment have announced plans for a new cooperative game app, "Marvel Mighty Heroes," a follow-up to 2012's "Marvel War of Heroes."

The new game lets players choose from their favorite Marvel comic book characters including Iron Man, Groot, Captain America, Star-Lord, Hulk, Thor, Black Widow and Spider-Man to build a dream team of Super Heroes and Super Villains in a game that can be played by up to four people at once.

"Marvel Mighty Heroes" is currently in development and will launch for iOS and Android devices this year.
