Watch Batgirl demolish the Joker's goons in the trailer for Batgirl: A Matter of Family. The add-on to Batman: Arkham Knight was developed by WB Games Montreal and will release first for season pass holders on July 14th, coming out separately for everyone else on July 21st. Pricing is given as $7.99 in North America. This add-on will only come to PlayStation 4 and Xbox One owners, as Rocksteady continues to work on fixing the PC version.

In A Matter of Family players will control Batgirl for the first time in the Arkham series, as she teams up with Robin  in order to saver her father from Harley Quinn and Joker. Since it takes place prior to all the Arkham games, Joker looks noticeably younger, and Harley is sporting her famous animated series outfit.
