2K Games has announced single-player downloadable content for BioShock 2. On August 3, the Protector Trials pack will have players defend Little Sisters against swarms of enemies in a variety of challenge rooms. The content will contain six maps based on locations from the main game, alongside three difficulty levels, seven Achievements/Trophies, and new concept art and videos to unlock. The pack will be available on Xbox 360 and PC for 400 Microsoft Points (£3.40) and PlayStation 3 for $4.99 (£3.50).2K Games announced they would not be able to offer the "Protector Trials" or "Minerva's Den" content on the PC, citing "Timing and technical issues" that they had encountered but could not work around.In late October 2010, 2K Games reversed their decision based on the players' responses, and have recommitted resources to complete the game patch and support for both content packs on the Windows version; the patch and "Protector Trials" would likely be available in December 2010, while more work is necessary to complete the "Minerva's Den" content.
