2K Games has announced that BioShock is gold and they also managed to sneak a demo of the game onto Xbox Live Marketplace. The 1.35 GB download has caused a flood of traffic, and some are reporting errors or stalls when trying to get their hands on a copy. If only PC gamers had such problems; 2K did confirm that they would be releasing a PC demo, but said only that it would be coming “later this month.”

Early reviews for the game have been exceedingly positive and with the game only a little more than a week from release, this should help hold you over for the next eight days.
