Arkham Origins story campaign DLC, after Warner Bros. made the decision to cancel it due to a lack of demand. WB confirmed the news in a statement given to VG247, after GoNintendo published a supposed Nintendo of America email spilling the bat-beans.
The Nintendo system and the latest Batman haven't been a dynamic duo, starting with WB not bringing multiplayer to the Wii U version for similarly quantitative reasons. WB's belated call to not give the Wii U further single-player content is curious, especially since there's other DLC from the game on the eShop, such as skins and challenge packs.
The one ray of good in today's news is that, going by the email published by GoNintendo, Nintendo of America is issuing a full refund to those who bought the season pass, despite some of the DLC it covers already being out. Whether that decision is WB's or Nintendo's, it is at least the right one.
