Today only, Games for Windows Marketplace offers downloads of Bioshock for Windows for $1.99. That's $3 under our December mention and the lowest price we've seen this title. (By comparison, Steam charges $19.99.) A free Xbox Live account is required in order to purchase games; however, you'll need to upgrade to a Gold membership in order to access certain online game content.
