Minerva’s Den is available today on the PlayStation Network and Xbox Live Arcade for $9.99 (that’s 800 Microsoft points).

Minerva’s Den introduces new characters and areas as the player teams up with Brigid Tenenbaum as you explore the Den. This includes a visit to Rapture Central Computing, a new location in Rapture, and encounter the ominous artificial intelligence running the show, The Thinker . The DLC includes new high-tech weapons (the Ion Laser) and a new Plasmid (the “Gravity Well”) — and Minerva’s Den introduces a new type of Big Daddy.

Developed by 2K Marin, Minerva’s Den is the final single-player-focused piece of downloadable content for BioShock 2 (read Will Herring’s 5-star review here.) For more details on Minerva’s Den, read this preview.
