BioShock 2: Minerva's Den

Minerva's Den is a single player downloadable content for BioShock 2. This additional campaign is a self-contained narrative experience that puts players in the role of another Alpha Series Big Daddy in a previously unexplored section of Rapture. Minerva's Den shows another vision of Rapture within Minerva's Den, a high-technology center of the city, and explores the backstory of the Thinker, a supercomputer responsible for the control of many automatic devices and systems in the underwater utopia, and its creator Charles Milton Porter. The player assumes the role of Subject Sigma, another Alpha Series Big Daddy, as he travels through Minerva's Den, home to Rapture's Central Computing.
