The first piece of DLC for Batman: Arkham Origins will be something of an origin story, Warner Bros. Games Montréal has announced.

Speaking at the Eurogamer Expo, producer Guillaume Voghel said that the Initiation DLC will take place in a monastery in Asia, and is the earliest playable sequence in the franchise's canon.

"You play as Bruce Wayne learning to be a ninja," said Voghel.

"That's a really cool one. Narratively there's some added content that will give players a little more background story."

According to Warner, the player will control Bruce Wayne before he becomes Batman as he tries to prove his worth to League of Assassins ninja Kirigi.

"It's not League of Assassins, it's ninja-related," said Voghel.

Voghel also detailed the game's I Am the Night mode, available after the completion of Arkham Origins’ New Game Plus mode.

"The main narrative arc and side missions last about 12 hours," he said, "and then you have all the collectibles.

“To get 100 per cent of that will take much, much longer. We have a new difficulty level, New Game Plus is coming pack – that's really difficult – and when you're done with that there's I Am The Night mode, which is no saves and one life."

Creative director Eric Holmes later clarified on Twitter that you can actually save your game in the mode, but a single death means the game must be restarted from the beginning.

Batman: Arkham Origins is due out for Xbox 360, PlayStation 3, Windows PC, and Wii U on October 25.
