Earlier this year, an internal marketing plan document leaked much of Warner Bros pre-release plans for Mortal Kombat XI. As time went on, the leak was proven to be completely accurate. Now, a very similar leak has seemingly given us a look at an unannounced DC game, which will seemingly combine multiplayer elements with the universe set up throughout the Batman Arkham games. We don’t know if Rocksteady is working on the game talked about in this leak. What we do know is that the project will be announced with a CG trailer in early June, followed by reveal trailers for specific characters and locations featured throughout the game. The leak specifically points towards playable versions of Gotham and Star City, with Arrow and Ra’s Al Ghul being the characters mentioned.
