BioShock 2 Getting Story-Expanding Add-On

2K Games' BioShock 2 is getting a new single-player focused downloadable game add-on that will include new characters, story and abilities, the developer said today.

Minerva's Den has players taking on the role of an all new character as they team up with Brigid Tenebaum to fight a dictator's hold on a district in the underwater city of Rapture.

"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 Christoph Hartmann, president of 2K. "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 add-on will take place in an entirely new district of the city and will include new weapons, new Plasmid, new Splicers, security bots that can shoot rockets and lightning bolts and a new type of Big Daddy.

No word on how much the add-on for the PC, PS3 and Xbox 360 game will be or when it is due out.
