2K games has released downloadable content and enhancements for Bioshock free of charge. The download is available for PC and Xbox versions of the game and adds four new plasmids and gene tonics to the game.
One of the new plasmids is called sonic boom, which hurls enemies back with a blast of force. EVE saver enables plasmids to use less EVE, Vending Expert reduces prices at vending machines, and machine buster allows the amount of damage player doles out to cameras, bots and turrets to increase.
The Xbox 360 version gets a new achievement that gives 100 points for “brass balls” achieved by beating the game on hard difficulty without dying. Another new feature is a widescreen option granting a wider horizontal field of vision and game enhancements. You can download the PC version of the patch at the link below.
