2K Games have announced Protector Trials, a new single-player DLC for Bioshock 2.

Protector Trials features six new maps based on locations in Bioshock 2 with three unique difficulty levels, new unlockables, including never-before-seen concept art and videos, and seven new Achievements/Trophies.

"The team at 2K Marin has been working hard ever since the launch of BioShock 2 to develop ways for gamers to extend their time in the single-player world of Rapture," said Christoph Hartmann, president of 2K. "I'm proud to announce the first of these experiences, the Protector Trials, which takes players back to some of their favorite places from the original game and features some of the biggest challenges that fans of this series have ever experienced. This is just the beginning. More single-player content is on the way that will deliver more of the intense action and story-driven gameplay that fans have been craving."

Protector Trials will be available on August 3 for the Xbox 360, PlayStation 3 and PC, costing 400 Microsoft Points on Xbox 360, PC and $4.99 on PlayStation 3.
