Super-rumour – Batman: Arkham Knight developer Rocksteady are working on a Justice League game
One insider has apparently spilled the beans on what Rocksteady has been up to since 2015, although said sources come from 4Chan and Reddit, so you might need to use the full power of the Infinity Gauntlet to pinch this level of salt. According to said tipster, Rocksteady has been busy with a Justice League game, titled Justice League: Crisis.
