BioShock 2 Minerva's Den DLC out August 31

Take-Two said today that BioShock 2's Minerva's Den DLC will ship on August 31 for $10 on PSN and 800 MSP on Live.

A PC version will come later.

The content adds three new areas and runs parallel to the main story, meaning you need not complete the BioShock 2 campaign before playing.

Minerva's Den contains six new Little Sisters.

Those who picked up Protector Trials will be given access to the Master Protector tonic in Minerva's Den, which simultaneously increases harvest times for any Little Sister you're chaperoning and the ADAM they collect.

This tonic can be accessed via any Gatherer's Garden.

Thanks, Joystiq.
