Injustice: Gods Among Us connects with the iOS version. Players will be able to unlock content for the console game while playing Injustice for iOS and vice versa on PlayStation 3 and Xbox 360 using a Warner Bros. ID.
This feature is not in the Wii U version. Siliconera received a Wii U copy of Injustice from Warner Bros. which confirms the cross device content unlocks are not in the Wii U release. The Wii U version has a few unique features like off TV play and the option to put a move list on the gamepad. You can toggle these options in the "gamepad screen" tab on the menu.
