Free Batman: Arkham Origins skin with WBID registration
People sure do love dressing up the Batman. And while youll have to shell out money for many of his alternate outfits, you can get something for free.
Registering for a Warner Bros ID (WBID) will get you a free skin for both the PC/console version of Arkham Origins and the iOS/Android mobile game as well. Logging in with a WBID in the PC/console version of the game will unlock the "One Million" skin, which is based on an alternate future set in the 853rd century.
Logging into the mobile game with a WBID will unlock "Red Son" Batman, who gets a few stat bonuses and special abilities. Linking both versions of the game to a single WBID will also let you unlock bonuses across both versions of the game.
