The forthcoming gameplay add-on for Batman: Arkham Knight featuring Batgirl (and Robin) in a Batman-free outing has just had its trailer drop, and for fans of the game series or Batman in general, it looks slick.

When The Joker kidnaps Commissioner Gordon and holds him hostage at the Seagate Amusement Park, Batgirl and Robin must fight against the odds to save him and avoid falling victim to The Joker’s sinister plan. Trained by Batman, Batgirl’s combat combines with unparalleled hacking abilities to take down enemies, control objects and solve puzzles.

The narrative actually takes place before the events of Batman: Arkham Asylum, likely setting up the game that kicked this whole Bat affair off, and is free for anyone who already grabbed the Batman: Arkham Knight Season Pass, otherwise it's around $10 on Xbox One and PS4 this July 15. No mention of PC in the press release, but given the desktop hurdles faced at launch, hopefully that's just to make sure it's actually ready.

Watch the trailer embedded below.
