Fresh off a trip to the go kart track, Rovio has announced the newest entry in its flagship franchise — Angry Birds Stella. Angry Birds Stella is breaking the mold by introducing strong, passionate characters who really stand for something, while adding plenty of action and reality into the mix, Rovio CEO Mikael Hed says. Like most of the recent Angry Birds games, Stella will include some sort of physical component, and Rovio says it wont be restricted to just a new game either: the studio is planning books, toys, and more. While details are scant, well likely learn more about the game soon, as Angry Birds Stella is slated to launch later this year.
