Owners of the Windows edition of Batman: Arkham Origins who register for a free WBID (Warner Bros. ID) on this page will receive a free DC One Million batsuit to help fill out their wardrobe in the stealth/action prequel (thanks Shacknews).

• In-Game bonuses--- Downloadable skins, extra consumables, and more
• Be among the first to know when sales and events are taking place
• Unlock great interactive content on WB Films and TV shows via BD Live
• Connection to the WB Shop
• Even more coming soon
