It appears that yet another game has leaked ahead of the official E3 announcement. Transformers: Devastation is a cel-shaded brawler akin to last fall’s Legend of Korra game from Activision and Platinum Games. Unsurprisingly, Activision is the reported publisher for this title, and while the developer is currently unknown Platinum did announce that an unannounced game would be revealed at E3 2015.
Pure Xbox says a “source” gave them several screenshots, which you can find below, and stated the game would release for Xbox 360. Knowing Activision, it is likely to release for every other console as well. You can view the screenshots and determine for yourself who the developer could be..
