The game came with a lenticular slipcover with a sticker over the standard case. The game case itself is labeled BLUS 31374 ZB11854WR. It came with a DLC sheet for The Fighting Chance Pack, a manual, and an advertisement for the season pass.
The exact same game was also sold without the slipcover, seemingly without any mention of the DLC contents.
