Batman: Arkham Origins already has more downloadable content (DLC) than you can shake a stick at. But besides all those sweet costumes and combat packs there is a new story driven DLC set to drop tomorrow December 3. Initiation throws gamers back into Bruce Wayne’s dark days of rope-fisted ninja training.

Arkham Origins now has an Inception level of prequel, going deeper and deeper. Besides punching people dressed as Ninjas, Bruce will also have a new mini challenge campaign with four new maps. The maps take place in the Paektu-San Mountains of North Korea where the government trains secret bands of advanced ninjas or mines uranium, whatever.

Batman: Arkham Origins new DLC Initiation drops tomorrow December 3 for PlayStation 3, Xbox 360, PC and Wii U. Gamers who already have the season pass, you already own it.
