If pre-order a game, most times, you get a little DLC pack that includes some exclusive content only available in the place you purchased the game. Eventually, all these little DLC packs come available to everyone down the line. However, the DLC you get when you purchase a console specific version of the game, generally stays exclusive to that console forever. However, Batman Arkham Knight is bucking the trend and making the PS4 exclusive content available to everyone this Fall. Check out the image to see the content and the confirmation that this exclusive content is only timed content.
