2K announces single-player BioShock 2 DLC, Minerva's Den

2K's said BioShock 2's final piece of DLC will be known as Minerva's Den.

The pack, which is for the game's single-player, sees you "in the role  of an all-new character who has teamed up with Brigid Tenenbaum to unravel a dictator's stranglehold on a key district in the distinctive city under the sea."

"Minerva's Den is a substantial addition that will give players more of what they're looking for: more story, more narrative, more gameplay and more of Rapture," said 2K president Christoph Hartmann.

"The core team has created an exciting product that further enhances the mystery and allure of the world of Rapture. Minerva's Den will be a fitting conclusion to the BioShock 2 saga."

The DLC will also feature new weaponry, a new plasmid and a "never-before-seen type of Big Daddy".

Minerva's Den releases this fall for PlayStation Network, Xbox Live Marketplace and Games for Windows Live Marketplace.
