After a little social-media teasing, GameStop has announced the Red Hood Story Pack DLC will be available exclusively to customers who preorder Batman: Arkham Knight from the retailer.

Developed by Rocksteady for Warner Bros. Interactive Entertainment and DC Entertainment, Batman: Arkham Knight is billed as the explosive finale to the hit action-adventure video game series that launched in 2009 with Batman: Arkham Asylum. (For a complete rundown, read CBR's coverage of the closed-door demo at E3 2014.)

Nothing is known about the Red Hood Story Pack, other than it introduces Jason Todd as a playable character, and features exclusive single-player missions. Those who preorder through GameStop will also get the Harley Quinn Story Pack, with four exclusive challenge maps, and a Batman 75th anniversary poster.

Originally set for release in October, Arkham Knight's debut has been pushed back to 2015.
