Turok Dinosaur Hunter - Missing track? by Lunar at 11:29 PM EST on October 31, 2005
Unless I've somehow missed it in the rip, the rip is missing the "underwater" music. I uploaded an mp3 of it <a href="http://lunar.shakal.net/Turok%20Dinosaur%20Hunter%20-%20Underwater.mp3">here</a>.
It's possible. In the game the music fades in when you go underwater... I guess it could be one of those instances where it's playing the whole time during the game but is only audible upon goin' swimming.
