UPDATE: The soundtracks have been removed from the GOW website. Tracks are still available!
The God of War III soundtrack, Blood & Metal, was supposed to be exclusive to the Ultimate Edition of the game, but it actually available to download for free from the God of War website (be quick, download links below). In addition, the complete God of War Trilogy soundtrack can also be downloaded for free. Is this a bug on the website or a reward for dedicated God of War fans?
The Blood & Metal EP weights in at just over 65MB, while the complete Trilogy soundtrack is is 300MB in size. Download the soundtracks for yourself below (direct from God of War website).
