---QUOTATION--- Subnautica: Below Zero - Official Trailer
Why the frowning face? It was a fun, lighthearted trailer, but I'm sure there will still be the terror of exploring dark icy depths. ---END QUOTATION---
To me the character in the trailer looked like something from an animated movie meant for small children. The actual game may not be in the same vein, of course.
"Also, for the first time, the original Subnautica soundtrack is available to purchase from Steam.
To make the soundtrack more readily available, we’ve moved the soundtrack from the game itself to additional content. If you already own a copy of Subnautica on Steam, you will automatically be credited with a free copy of the soundtrack to download. You can find and download this directly from the game listing in your Steam Library."
