More details on the Harley Quinn downloadable content pack for Rocksteady’s upcoming Batman: Arkham Knight have surfaced. As shown on the Batman: Arkham Knight Amazon page (via Cinemablend) the exclusive DLC will allow players who pre-order the game to assume the role of Harley Quinn and “wreak havoc inside the Blüdhaven Police Department.”

The DLC pack’s story will take place prior to the events of Arkham Knight, and tasks Quinn with the goal of infiltrating Blüdhaven in order to rescue Poison Ivy. The Harley Quinn DLC was first announced in July last year, and will include four challenge maps that will allow you to play as the jester and “utilize her unique weapons, gadgets, and abilities.”

Alongside the PlayStation-exclusive Scarecrow nightmare missions announced at E3, it looks like there is going to be a substantial amount of downloadable content for Arkham Knight. Check out what the game looks like on PS4 in this recently released gameplay video. Batman: Arkham Knight is scheduled to launch on June 23 for the Xbox One, PS4, and PC.
