Well, aren't we lucky? 2K has announced that they will be releasing a patch, for the PC, and DLC, for the 360, for their game Bioshock. I'll let IGN do the talking :).

Source (http://uk.xbox360.ign.com/articles/838/838862p1.html)US), November 30, 2007 - A patch and a selection of free downloadable content will be available next week for both the PC and Xbox 360 versions of BioShock, developer 2K Games said today.

According to the game's official Cult of Rapture web site, a PC patch and Xbox 360 title update will go live next week, and both will also include additional content. 2K's Elizabeth Tobey told IGN that, among other things, the download will include new plasmids and a change to the game's widescreen field of vision.

A full list of bug fixes and extra content will be posted on the Cult of Rapture site when the patches are ready, 2K said.

In October, BioShock creator Ken Levine told 1up that the game's future downloadable content would likely take the form of combat enhancements or other gameplay additions rather than new levels. Levine has also said number of plasmids were cut from the final game.New plasmids; woo!
