Subnautica OST

In Subnautica, there are many sounds, soundtracks and sound effects that are present. Most sounds have not been released as a file to the public, yet. A Full Subnautica Soundtrack is planned to be released at V1.0 as stated here and the soundtracks are currently being named and assembled. All Sounds were and are created by Simon Chylinski.

Music
The Subnautica Soundtrack was available through the Subnautica Special Edition, which included other exclusives such as the Special Hull Plate Upgrade and some early prototypes. It is assumed to be available on Steam later.

The tracks were provided as MP3 and in lossless quality as FLAC and WAV.

Some tracks are uploaded on the official Subnautica Youtube and Soundcloud pages, while others are uploaded on the Music Developer, Simon Chylinski's Soundcloud.
