2K Games is busy today announcing that Bioshock 2’s final single player DLC pack, Minerva’s Den, is now available for download on the Xbox 360 Marketplace for 800 Microsoft Points and from the PlayStation Network for for $9.99.

Minerva’s Den is a self-contained narrative experience that introduces new characters, locations and mystery to the fiction-rich world of Rapture. The game add-on puts players in the role of an all-new character who has teamed up with Brigid Tenenbaum to unravel a megalomaniac’s stranglehold on a key district in the distinctive city under the sea.

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