2K has announced that the single-player story-driven Minerva's Den add-on for BioShock 2 will be released next Tuesday, 31st August.
Minerva's Den will go for $9.99 on PlayStation Network and 800 Microsoft Points (£6.80 / €9.60) on Xbox Live Marketplace. A PC version will follow later.
The DLC consists of three new areas to explore, home to six more Little Sisters, and can be tackled even if you haven't finished the game.
If you already own Protector's Trials, you can also buy a new Master Protector tonic at any Gatherer's Garden - it speeds up harvest times for Little Sisters you're protecting and amps up the amount of ADAM they collect.
2K president Christoph Hartmann recently described Minerva's Den as "a fitting conclusion to the BioShock 2 saga".
