The origins of Batman are pretty well known by comic book fans these days – Bruce Wayne's parents are killed, and he soon toughens up and becomes Gotham City's avenger – but now you can play the legacy for yourself, as WB Games will release a new Initiation DLC pack for Batman: Arkham Origins starting tomorrow.

In this new pack, you'll be able to take on four new challenge maps – varying from bamboo forests to a remote monastery – as you play Bruce before he becomes the Bat. You'll rely on his skills and techniques to get through each map, slowly but surely becoming the Dark Knight.

This DLC will also include a pair of exclusive skins, including Bruce Wayne's Initiation suit and Vigilante Bruce Wayne. You can see it in action in the trailer below.

Initiation will be available for PlayStation Network, Xbox Live, Steam and the Nintendo Wii U eShop starting tomorrow for $6.99. If you already have the Batman: Arkham Origins Season Pass, it's free of charge.
