What the developers have to say:

Why Early Access?

“We make our best games when you are involved from the start. The earlier you play, the faster we hear what you want. You can see our plans, our progress, our successes and our failures. This is how we built the original Subnautica. By involving you in the development process, and iterating openly on your feedback, we build better games.”

Approximately how long will this game be in Early Access?

“We can't accurately predict how long Early Access will take. We expect at least approximately one year, and potentially more.”

How is the full version planned to differ from the Early Access version?

“Throughout Early Access, we will release a sequence of updates that add new content to the game. Initially, you will only be able to play in the starting zone and surrounding Biomes. Future updates will add new vehicles (like the Hover Bike), new biomes, and new story areas. Bugs will be steadily reduced and performance steadily increased.”

What is the current state of the Early Access version?

“Below Zero offers currently 1-2 hours of story play time. Starting environments are richly detailed, voice acting is present, and bugs are frequent but often not game-breaking. Performance (frame rate) is poor relative to what we want in the finished game. See the "About This Game" section for more information about what features are implemented so far.”

Will the game be priced differently during and after Early Access?

“The price of Subnautica Below Zero will increase by 25% when we release the finished version.”

How are you planning on involving the Community in your development process?

“Please join us in developing Subnautica: Below Zero. You can follow our progress on Twitter, Facebook, YouTube, Instagram, the Steam Community, and the Subnautica Blog. Receive notification of major update release by signing up to the Subnautica Development newsletter. You can see real-time changes to our source code by following @SubnauticaSCM on Twitter, and give us feedback using the in-game feedback system. The whole development team is available to chat on Twitter, in Discord, and on our forums. See our tasks being tracked in real time on Favro.

Return to planet 4546B


Dive into a freezing underwater adventure. Below Zero is set in an arctic region of planet 4546B. As a scientist posted to a research station on the planet's surface, you are tasked with studying alien artefacts...

The Vesper space station orbits high above you, sending supplies, instructions, and receiving samples you launch from the surface.When disaster strikes the research station, you must improvise to survive: Construct habitats, scavenge for resources, hunt for food, and craft equipment.

Explore new biomes


Swim beneath the blue-lit, arching growth of Twisty Bridges. Navigate treacherous ice floes on the ocean surface. Clamber up snow covered peaks, and venture into icy caves. Maneuver between steaming Thermal Vents. Below Zero presents entirely new environments for you to survive, study, and explore.

Discover new lifeforms in the icy depths of 4546B. Swim through the giant Titan Holefish, escape from the aggressive Brute Shark, and visit the adorable Pengwings. Some residents of the frozen ocean will help you, and some might try to harm you.

An ocean of intrigue


Who were the aliens who came here before? Why were they on this planet? Can you trust your commanders? Below Zero extends the story of the Subnautica universe, diving deep into the mystery introduced in the original game. Open up new story elements with every Early Access update.
