On the posters both Batman and The Flash battle it out, the characters were also prominently featured in the first game Injustice: Gods Among Us. The second game is expected to the direct sequel to the original title that was released back in 2013.
The game is expected to release later this year for Xbox One and Playstation 4. A PC release has not yet been confirmed.
