Story-based downloadable content is now in production for The Last of Us.

In a post on the PlayStation Blog, Naughty Dog community strategist Eric Monacelli said that the casting call for a new character was complete, and that the studio was starting performance capture this week.

“This is an ambitious story with strong ties into the narrative of The Last of Us,” said Monacelli.

The DLC is currently planned for release around December-January.

In the meantime, a multiplayer map pack called Abandoned Territories will be released on October 16.

Said Naughty Dog:

Weather the opposing Faction and the random, dynamic dust storm on the Suburbs map. Explore a layered map of an overgrown urban environment in the Bus Depot map. Stalk around in a dark, eerie, moonlit, environment – the perfect setting for some serious stealth – in the Hometown map. Bookstore features a stacked, bi-level layout adding a highly unique dose of vertical gameplay.

The third piece of DLC that rounds out the game’s Season Pass offering is multiplayer-focused and will arrive in the first half of 2014.
