2K Games, a publishing label of Take-Two Interactive Software, Inc., announced today that the demo of BioShock is now available on Xbox LIVE Marketplace for the Xbox 360 video game and entertainment system from Microsoft. The BioShock Windows PC demo will be available for download later this month.

Developed by 2K development studios, 2K Boston and 2K Australia, BioShock is a highly anticipated first-person shooter that will be available exclusively on Xbox 360 video game and entertainment system from Microsoft and Games For Windows in North America on August 21, 2007 and in Europe beginning August 24, 2007.

BioShock is a "genetically enhanced" first-person shooter that lets players do things never before possible in the genre – turn everything into a weapon, biologically modify your body with plasmids, hack devices and systems, upgrade weapons and craft new ammo variants, and experiment with different battle techniques.

The Xbox 360 demo introduces gamers to BioShock by inviting them to explore the world of Rapture, an underwater utopia torn apart by civil war. While immersed in the decaying art deco city, gamers can experiment with the various weapons and plasmids, as the captivating storyline unfolds. Caught between powerful forces and hunted down by genetically modified "splicers" and deadly security systems, players have to come to grips with a deadly, mysterious world filled with powerful technology and fascinating characters. No encounter ever plays out the same and no two gamers will play BioShock the same way.

BioShock is rated “M” for Mature. For more information, visit the BioShock website at: www.2kgames.com/bioshock.
