zykour: I bought the collector's edition but can't seem to find the bonus content anywhere in the GOG Galaxy/Games/Creaks directory. if anyone knows where it would be located, I'd be much obliged. Thanks!
It is an extra download not in the main game download. I'm not sure how that works with Galaxy but you can at least easily get it from the website. The soundtrack is available in both FLAC and mp3 formats and the FLAC download is over 1GB.
