Subnautica: Below Zero has received its first big Early Access update. Check out the Seatruck Update Site to see all the sweet new features in action.

  • Seatruck modular underwater utility vehicle
  • Terrifying Squidshark creature 🦑
  • Thermal Spires & Deep Twisty Bridges biomes
  • Playful Seamonkey and their nests
  • Intricately detailed Cargo Transfer Launchpad island
  • Lots of small Early Access improvements

The Seatruck



The Seatruck is a modular Underwater Utility Vehicle. Start by building a cab, then add and remove modules based on your mission requirements. Each additional module slows the Seatruck down. A reversing camera is included as standard. In an emergency, you can detach all modules and escape quickly.

  • Fabricator - Mobile field equipment fabricator
  • Storage - Ample space for equipment & supplies
  • Aquarium - Collect live specimens



Look out for more Seatruck modules in future Early Access updates!

Squidshark



Lurking within the new Deep Twisty Bridges biome, the Squidshark is a serious threat. Its tentacles can ensnare even the most agile diver. Shark teeth and a powerful bite cause great damage.

Seamonkey



An ocean trickster, the Seamonkey will actively seek to steal your kit and swim off with it. Follow them back to their nests and you might find other valuable things they have collected.



Deep Twisty Bridges



Deep Twisty Bridges is a dark, red-accented region with depths exceeding 200 meters. Look out - Some of the plant life is not passive, and might ensnare you in the depths.

Thermal Spires



Rockpunchers and Bonesharks roam between these pointed ocean stacks.

Cargo Transfer Launchpad



Explore a richly detailed island, home to the Cargo Transfer Launchpad. Black sandy beaches, thermal pools, snow-dusted cliffs and intricate caves await you. At the peak, you will find a new Cargo Transfer Base along with attendant rocket launchpad.

Below Zero Early Access



Subnautica: Below Zero is now available in Early Access! Set one year after the original Subnautica, Below Zero challenges you to survive a disaster at an alien research station on Planet 4546B.

This frozen underwater adventure is a work in progress. As we did with Subnautica, we are building Below Zero out in the open. With your help, we will craft a worthy follow up to the original game.

Below Zero is full of bugs, runs poorly, and includes only a small portion of our planned features. It's also a game we're excited about. If you join us, we think you might enjoy this journey through Early Access.

If you would like to wait until the game is finished, please sign up to our Development Newsletter. We'll let you know as soon as the game is done!

About This Game

Subnautica is an underwater adventure game set on an alien ocean planet. A massive, open world full of wonder and peril awaits you!

Dive Into a Vast Underwater World




You have crash-landed on an alien ocean world, and the only way to go is down. Subnautica's oceans range from sun drenched shallow coral reefs to treacherous deep-sea trenches, lava fields, and bio-luminescent underwater rivers. Manage your oxygen supply as you explore kelp forests, plateaus, reefs, and winding cave systems. The water teems with life: Some of it helpful, much of it harmful.

Scavenge, Craft, and Survive




After crash landing in your Life Pod, the clock is ticking to find water, food, and to develop the equipment you need to explore. Collect resources from the ocean around you. Craft diving gear, lights, habitat modules, and submersibles. Venture deeper and further form to find rarer resources, allowing you to craft more advanced items.

Construct Underwater Habitats




Build bases on the sea floor. Choose layouts and components, and manage hull-integrity as depth and pressure increase. Use your base to store resources, park vehicles, and replenish oxygen supplies as you explore the vast ocean.

Unravel the Mystery




What happened to this planet? Signs abound that something is not right. What caused you to crash? What is infecting the sea life? Who built the mysterious structures scattered around the ocean? Can you find a way to make it off the planet alive?

Disrupt the Food Chain




The ocean teems with life: Use the ecosystem to help you. Lure and distract a threatening creature with a fresh fish, or simply swim as fast as you can to avoid gnashing jaws of roaming predators.

Handle the Pressure




Build a Pressure Re-Active Waterproof Nanosuit, or PRAWN Suit, and explore extreme depth and heat. Modify the suit with mining drills, torpedo launchers, propulsion cannons, grappling hooks and more.

Fear the Night




As the sun goes down, the predators come out. The ocean is unforgiving of those caught unprepared in the darkness. Areas that are safe to explore during the day become treacherous at night, but also reveal a beauty that those who hide from the darkness will never see.

Dive Below the Ocean Floor




Cave systems wind below the sea bed, from dark claustrophobic passages to caverns lit by bio-luminescent life and burning-hot lava flows. Explore the world below the ocean floor, but watch your oxygen levels, and take care to avoid the threats lurking in the darkness.

Open Development




Get weekly or daily updates, see what the development team is working on, view real time change logs, and give feedback from inside the game. Subnautica Early Access development is open, and the development team wants to hear from you.

About the Development Team




Subnautica is being created by Unknown Worlds, a small studio founded by Charlie Cleveland and Max McGuire that traces its roots back to the 2003 Half-Life mod Natural Selection. The team is scattered around the globe, from the United States to the United Kingdom, France, the Czech Republic, Russia, Thailand, Australia, and many more places. There is a central office in San Francisco, California that serves as home base for the whole team.
