In a report from Video Games Chronicle, the upcoming WB Montreal Batman game may include Batgirl somehow. While including Batgirl would be awesome, this isn't confirmed by WB Montreal and it could be false."This may be just a coincidence, but if you put all the codes together to unlock the four teasers from R3DAKT3D.com, you get "761941364995", which is the EAN number for Detective Comics #359, the debut of Batgirl," said in a tweet from Twitter user @ArkhamVideos. "WB Montreal developed Batgirl's DLC for Arkham Knight." 

In a follow-up tweet, a member of the Arkham Videos Discord uncovered that the covers for Detective Comics 359 is similar to the cover of issue 43 for Batman: Gotham Knights. This could lead to WB Montreal's upcoming Batman game is called Batman: Gotham Knights. The comic series of the same name ran from 2000 to 2006 and explored different Batman family members such as Alfred, Nightwing, and Batgirl among others.

WB Montreal's Batman game has been teased since last year, with a focus on the Court of Owls.
