Injustice: Gods Among Us, NetherRealm Studios' upcoming DC Comics superhero fighting title, will include The Joker and Green Lantern, according to leaked images of the game's box art seen on All Games Beta.
The cover also features many previously announced characters: Batman, Superman, Cyborg, Wonder Woman, Flash and Green Arrow. The images have not been confirmed as the official cover artwork, but NetherRealm's Ed Boon said earlier today on Twitter that a screenshot of The Joker and Green Lantern would be coming today. Boon told Polygon last week that picking an arena will be as important as choosing a character.
Injustice: Gods Among Us is set for release in April 2013 on Xbox 360, PlayStation 3 and Wii U.
