BioShock demo zaps Xbox Live

Despite flying new colors under its newly dubbed moniker 2K Boston, the studio formerly known as Irrational Games seems to be unwavering on its projected August 21 release date for BioShock. As evidence of that fact, and perhaps to prove that not all of Take-Two's aggressively anticipated games have hit the skids, 2K Games unveiled a demo for BioShock on Xbox Live over the weekend.

Weighing in at a hefty 1.35GB, the demo offers gamers a preview of the open-ended gameplay for 2K Boston's science-experiment-gone-wrong first-person shooter. Players will have access to a variety of weapons and utilities as they explore the remnants of a decaying city, while warding off genetically altered monstrosities and navigating the perils of a technically advanced society. Gamers looking to parse out their precious holiday dollars should check out GameSpot's previous coverage for a more in-depth look at the game.

Following up on the Xbox 360 demo, 2K Games today announced that a PC demo will be available later this month. Rated M for Mature, the full version of BioShock will be available for the PC and Xbox 360 for $49.99 and $59.99, respectively.
