With the sudden cancellation of the collectors edition of Batman: Arkham Knight due to manufacturing issues, Warner Bros has released the exclusive skins pack which would have come with the addition for free.
If you want to get the New 52 skins pack, you need only head over to the PlayStation Store and download it free of charge. The pack includes a new skin for Batman, Robin, and Nightwing. This is good news for your average Batman gamer, but is probably of little comfort to those who pre-ordered the collectors edition, only for it to be canceled less than a week before the game launched.
Other than Warner Bros being unhappy with the quality of the collectors edition, a specific reason for why it was so suddenly canceled has not been given. With any luck, Warner Bros will try to make it up to fans who had their hearts set on the collectors edition.
