A few days after the release of the Protector Trials DLC for Bioshock 2, 2K Games has announced Minerva’s Den, an all-new single-player focused downloadable game add-on for BioShock 2 that introduces new characters, locations and mystery to the fiction-rich world of Rapture.

In development for the Xbox 360, the PlayStation 3 and Games for Windows-LIVE, Minerva’s Den is a self-contained narrative experience that puts players 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.

Players will wield new high-tech weaponry and a devastating new Plasmid to best the towering threats in Minerva's Den: more dangerous Splicers that command the power of the elements, upgraded Security Bots that throw rockets and lightning bolts, and even a never-before-seen type of Big Daddy.
