Help Clean Our Planet's Oceans



***This event has now ended***

In celebration of World Environment Day on June 5th, Subnautica will go on sale alongside several other games as part of a Valve special event until June 8th. During this time, we volunteered to donate 15% of Unknown Worlds’ profits from the sales of the original Subnautica to the Ocean Cleanup, a Dutch foundation that aims to develop and apply technologies (directly as well as indirectly) to remove – on a large scale – plastic pollution from the oceans.

Not unlike the virus that threatened Planet 4546B, our planet is threatened by a mass accumulation of garbage in the ocean. Marine debris, out of which 80% is plastic, has been reported to have an impact on 600 marine wildlife species. This marine debris accumulates in patches across the planet by way of ocean currents, waves, and wind. It poses a significant threat to the ecosystem, the health of both marine life and humans, and global economies.

According to the U.S. Environmental Protection Agency:

“Of all trash, plastic trash has the greatest potential to harm the environment, wildlife and humans. It can be found floating at the surface, suspended in the water column, or on the bottom of almost all water bodies. It is transported by rivers to the ocean, where it moves with the currents, and is often eaten by birds and fish, concentrating toxic chemicals in their tissues, and filling their stomachs, causing them to starve. Plastic aquatic debris is much more than a mere aesthetic problem.”

Cleaning up these garbage patches is a tough job, but not an impossible one. Through intense research, advanced technology, and the clever use of natural ocean systems, the Ocean Cleanup has set their sights on removing 50% of the Great Pacific Garbage Patch in just 5 years. To learn more about how they plan to do this, you can read in-depth explanations and reports on the Ocean Cleanup website.

In Subnautica, you were affected by a major environmental threat and, through scientific efforts and hard work, elimited that threat. Now is your chance to do the same for our home planet. Let your friends and family know that Subnautica is on sale and working towards a cleaner ocean!

About World Environment Day

The United Nations, aware that the protection and improvement of the human environment is a major issue, which affects the well-being of peoples and economic development throughout the world, designated 5 June as World Environment Day. The celebration of this day provides us with an opportunity to broaden the basis for an enlightened opinion and responsible conduct by individuals, enterprises and communities in preserving and enhancing the environment.

About The Ocean Cleanup

The Ocean Cleanup specifies the following objectives:

  • To develop and apply technologies (directly as well as indirectly) to remove – on a large scale – plastic pollution from the oceans;
  • To develop and apply technologies (directly as well as indirectly) to remove plastic pollution from waste streams to prevent it from reaching the oceans;
  • To increase social awareness of the pollution of the marine environment by plastic; and other acts which in the broadest sense relate or may be conducive to the aforesaid objectives.

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.
