Purchasers are reporting multiple issues pertaining to downloadable content bundled with Batman: Arkham City.
Reports on the game's official forums range from receiving blank code slips for the Catwoman first-purchase bonus; scoring multiple copies of the same code but missing others; and activation failure of Robin DLC codes.
Warner Bros. has also noted that some Collector's Edition feature a DVD insead of a Blu Ray copy of Gotham Knight, or are missing the collector's cards.
Batman: Arkham City is out now in Australia and the US for PlayStation 3 and Xbox 360, with the UK launch on Friday. A PC version has been delayed to November worldwide.
