2K Games has announced that a BioShock PC patch and Xbox 360 title update, as well as a free downloadable content pack for both Xbox Live and for the PC, will be released this week. For now, the content pack will include several extra plasmids for players to use while the patch will fix the game's field-of-vision perspective. A full list of bug fixes and everything included in the DLC will be put up on The Cult of Rapture
when the downloads become available.
