Subnautica, the underwater survival game from Unknown Worlds Entertainment, has received its first significant update in a good while, and the patch notes say there are hundreds of bug fixes. Considered a strong release in the survival genre, the indie title sits up there with the likes of Stranded Deep, ARK: Survival Evolved, and even Minecraft. However, it offers something a little different to other games in that it takes place entirely in an ocean, which makes it something of a horror game for many.
