2K Games has released MP3 versions of all twelve BioShock tracks that play while venturing through Rapture. The announcement:
Composer Garry Schyman created the orchestral masterpiece that serenades you through your journey into the heart of Rapture. Today, we are releasing the 12 tracks that create the eerie string compilation in Rapture so that you can take the world of BioShock wherever you go. We have archived these 12 mp3s into a zip file for you for easy download. Grab it and take a listen -- and remember the first moment setting eyes upon the sunken city, your first battle with a Splicer, when you first battled a Big Daddy, or the time you decided to save (perhaps harvest?) a Little Sister.
