Subnautica is one of the most successful survival games that's on Steam. One of it's most iconic sea creatures is the Sea-Dragon Leviathan, I've just made a live wallpaper of it with it's antennas glowing and the lights down it's chest and stomach as well as it's tentacles glowing with the ocean's waves moving and the bubbles from it's mouth moving with the bottom of the picture darkened to give it more of that deep ocean look Enjoy!
