Injustice: Gods Among Us on Wii U doesn't support content unlocks with iOS game

The Wii U version of DC Comics-themed brawler Injustice: Gods Among Us does not support cross-device content unlocking with the iOS version, reports Siliconera.

The iOS app, released earlier this month, allows players to earn content for use in the PlayStation 3 and Xbox 360 versions, and vice versa, with a valid Warner Bros. ID. However, the feature does not seem to be supported by the Wii U version. According to Siliconera, a Wii U copy obtained by the publication confirms the feature is missing.

Giant Bomb's Jeff Gerstmann also tweeted that the Wii U version was "missing stuff," including the cross-device content feature.

Wii U version of Injustice is missing stuff. No lobby system online (which I think means online practice is gone). Doesn't tie into iOS app.
