WB Games will offer a special Serious Edition of the upcoming Batman: Arkham Knight video game that comes with a limited-edition 25th anniversary hardcover of Arkham Asylum: A Serious House on a Serious Earth, by Grant Morrison and Dave McKean.

Although the $70 comic bundle, which includes the video game and an in-game skin of Batman as he originally appeared in Detective Comics #27, hasn't been officially announced, it was spotted on the Amazon.com listing. According to the ad, it will only be available for Xbox One and PlayStation 4.

Developed by Rocksteady Studios, Batman: Arkham Knight follows the Caped Crusader at the peak of his abilities, as Scarecrow returns to Gotham City to unite his foes to finally kill the Dark Knight. It's billed as the explosive finale to the hit action-adventure franchise.

Batman: Arkham Knight arrives June 23.
