Subnautica: Below Zero is an underwater adventure game that takes place on an alien ocean world. The game is currently being developed by Unknown Worlds Entertainment, and it is a new chapter in the Subnautica universe. As a scientist posted to a research station on the planet's surface, you are tasked with studying alien artifacts. The game is set in an arctic region of planet 4546B, and it features entirely new environments for you to survive, study, and explore. Below Zero is not finished, so it is full of bugs, missing features, and performance issues. However, as updates improve the game, the developers will keep you informed about the game's development progress.
