Another reason to adore the game is Michael Geyre's amazing arranged soundtrack, which uses Shinichi Sakamoto’s original tunes and updates them in some truly wonderful ways. If you've been humming those iconic songs since launch then you'll be pleased to learn that the official soundtrack is now available on Steam and Bandcamp.
33 main tracks are included, which is over an hour of music. However, that's not all - 56 bonus tracks provide an extra hour of "alternate versions, sketches, unused and/or rejected material, offering deep insight into the composition and arrangement process."
You can pick this up for just $4.99, or $3.99 if you purchase the game on Steam at the same time.
