While some people have been more than content enough buying extra skins for Batman in Batman: Arkham City, those who have abstained from buying any DLC from the title will be glad to hear that Rocksteady is actually going to be releasing a Batman skin for the price of nothing. The Batman Inc. costume which can be seen above will be free on December 21st on Xbox Live and PSN.
Plus if you want to wear any costume early before you end up beating the game, you can now enter in this code to wear any costumes you own. Players must enter the code after they select their save file and press Left, Left, Down, Down, Left, Left, Right, Up, Up, Down.
