The German edition came with a unique game disc, but disc 2 is the same as that which came with all the other European editions. It came with a manual. The cover insert could be flipped over to reveal the artwork without the USK ratings logo, PS3 logo, and barcode.
A Steelbook edition was not released in Germany, but a Steelbook was offered as a pre-order bonus.
