With less than a month to go until Rocksteady Studios releases its bittersweet (and brutal) ending to its Batman: Arkham trilogy, the upcoming Batman: Arkham Knight has already riled some attention for its notable pre-order bonuses, DLC, and its Season Pass, and now a new-preorder bonus has appeared if you haven't been enticed to see how The Dark Knight's story ends just yet.

Over on the Steam store page for Batman: Arkham Knight, a new pre-order bonus DLC pack has appeared in the game's listing that includes two new costumes for Batman in Arkham Knight - the DLC is available with pre-orders of the game through Steam, though it has not been officially confirmed just yet for other platforms.

Titled the "Gotham's Future Skin Pack," the pre-order bonus DLC includes one costume based on the animated series Batman Beyond, while the other contains a costume based on the classic Frank Miller graphic novel, The Dark Knight Returns.

Batman: Arkham Knight will release for PS4, Xbox One, and PC on June 23rd, 2015.
