Earth's oceans need you



Update 12 Jun 2018 - the WDC sale has ended, thank you everyone who participated

You saved the underwater world of planet 4546B. Here on Earth, our own oceans need your help. This weekend, we are joining forces with Valve and the ocean charity Whale and Dolphin Conservation (WDC). 15% of Unknown Worlds’ profits from the sales of Subnautica will go to WDC.

4546B is a world covered in water. Earth is not so different: 71% of the Earth’s surface is covered in water. Startlingly, they contain around 90% of the Earth’s biomass. That means that there is far more life under the water than above it: Out of sight, and often out of mind.

Agricultural runoff, drag-net fishing, deforestation, plastic waste, even acidification via increased carbon-dioxide levels in the atmosphere. Earth’s oceans are taking damage from multiple sources. Life below the waves is dying, shrinking, and disappearing.

We made a game that takes you to an alien world, a world that needs your help. You saved that world. This weekend, we ask that you think about ways in which you can help to save the Earth.

About WDC

WDC is a global organisation that works to:

  • Create healthy seas, including tackling plastic pollution in our oceans
  • Put an end to hunting and commercial whaling
  • Tackle bycatch, an accidental entanglement in fishing gear, which kills an estimated 300,000 whales and dolphins every year
  • End the cruel practice of keeping whales and dolphins in captivity

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.
