I purchased DLC for Batman: Arkham City a few months back and I went in to look if there was any new DLC I could get. To my surprise most of the content I payed for is marked as unbought so I cant download it again without paying for it again which is bs. The content I'm sure I'm missing is Arkham city skins pack, robin bundle pack, and kightwing bundle pack. The only other one I believe I also payed for but cannot be positive and it is Challenge Map Pack. Would really love to get what I payed for back. As proof of ownership of most of the DLC stated above, check out my achievements I have to even own Robin and Knightwing just to get some of the ones I have.
