Batman Arkham Knight is getting it's first DLC

The first story based DLC has been given a date a price.  The title is "Batgirl: A Matter of Family" and will be free for those who purchased the season pass and cost $6.99 for those who did not.  It will be release on the Xbox One and PS4.  Unfortunately, The PC version of Batman Arkham Knight had some major issues during the release and was eventually removed from Steam and because of this there is no Release date for the Batgirl DLC on PC at the time.  

The DLC is set at a time prior to any of the other Arkham games and in a different location.  For more information visit my source at Gamespot.com.
