"This includes the Harley Quinn and Red Hood Story Packs, as well as any Batmobile or Booster Pack that was available as early bonuses for pre-order of the game”, Rocksteady's admin Yorick said.
This news comes after it was revealed that the Arkham Knight Batmobile Edition was cancelled due to a last minute production error. This is not so good for those who pre-ordered as the Limited Edition is becoming quite hard to find, so to make up for this Warner will be providing everyone who purchases Batman: Arkham Knight with the New 52 skin pack, including Batman, Robin and Nightwing, free of charge. A bonus for everyone then.
Batman: Arkham Knight is out June 23 for PlayStation 4, Xbox One, Windows, Linux and Mac OS.
