Arkham Knight's Batgirl DLC set before Arkham Asylum

The first DLC for Batman: Arkham Knight, Batgirl: A Matter of Family, will take place before the events of Arkham Asylum.

In Batgirl: A Matter of Family, Barbara Gordon will team up with Robin to save Commissioner Gordon, who has been kidnapped by the Joker.

As with Arkham Knight, players will occasionally be able to take advantage of the Dual Play combat system to switch between characters and perform team-based takedown moves.
