A new trailer for the Batman: Arkham Origins add-on downloadable content pack, Initiation, shows us the Caped Crusader during his salad days.

The upcoming DLC will feature a young Bruce Wayne as he takes an initiation test in the Paektu-San Mountains of North Korea. His martial arts prowess will be put to the test as he trains in different locations, such as a bamboo forest and a monastery on top of a mountain.

At the end of his journey, he'll have to face his teacher: a man named Kirigi. The Initiation challenge map DLC is available starting today. Download it and help Bruce Wayne gain the skills he needs to become the Bat.

Watch the trailer above to get a taste for what you'll be doing in the mountains and see how awesome it is to witness Bruce Wayne taking out a bunch of ninjas.
