Warner Bros has revealed the trailer for the Batgirl-focused expansion, A Matter of Family.
Set prior to the events of Arkham Asylum, A Matter of Family lets players take control of Batgirl for the first time in the Arkham series.
The trailer itself shows off Batgirl battling thugs and appears to be much quicker than Batman. Additionally, various gadgets and some of series most famous villains are displayed as well. As far as story elements go, Batgirl will team up with Robin to rescue Commissioner Gordon who has been captured by Joker.
Batgirl: A Matter of Family will be available July 14 for players who purchased the season pass. If not, players can also purchase the expansion separately on July 21.
