***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!


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.


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.

Travel quickly across the snowy tundra on a Snowfox, hide from terrifying beasts, explore two new biomes, and more in the latest update to Subnautica: Below Zero Early Access. Check out the Snowfox Update site to learn more!

• Snowfox vehicle
  
• Chelicerate & Snow Stalker
  
• Two new, beautiful biomes
  
• New fishy friends and foes
  
• Seatruck Sleeper and Docking Modules, Perimeter Upgrade

The Snowfox is the first above-water vehicle in the Subnautica universe. Travel quickly over land, all without touching the ground! The Snowfox can be upgraded with a jump module (coming soon), and comes with a speed boost ability built in. Build a Snowfox Hoverpad (with power) to craft the Snowfox and customize it however you like!




A new beast appears on land in the latest update. A deadly creature with long claws and a powerful charge, Snow Stalkers are aggressive and best avoided. Especially when they are with their offspring!




Beautiful no matter the weather, the new Glacial Basin biome is home to an array of creatures including the Snow Stalker. Teeming with icy nooks to explore, this biome has a lot to uncover.




Lurking in the new Purple Vents biome, the Chelicerate is a Leviathan-class creature with a nasty bite. Not much is known about this massive monster of the water.




Explore the hauntingly beautiful Purple Vents biome, a shallow-depth environment. Underground thermal activity erupts into bright purple particulate, providing the perfect ecosystem for many creatures.




Three new additions to The Seatruck are now available; The Sleeper Module, the Docking Module, and the Perimeter Upgrade.

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 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.

https://youtu.be/OhK_LERt4so

• Cab - Provides power, live support, cockpit
  
• 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!




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.




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 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.




Rockpunchers and Bonesharks roam between these pointed ocean stacks.




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.

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!

- Unknown Worlds

https://store.steampowered.com/app/848450/Subnautica_Below_Zero/

You are invited to a special Subnautica livestream event! Please join us on January 30th, 6PM UTC as we premiere the Below Zero Early Access Trailer and launch Early Access on the Steam store.

Below Zero is not finished. It is full of bugs. It lacks polish, runs poorly, and is missing features. We are offering Early Access not because we want your money, but because we want your feedback. We make better games when we make them with you.

You can watch the stream on YouTube, Twitch, or on the Below Zero Steam Store page. Checkout the the Early Access site to see a countdown to stream start, and add the stream start time to your calendar.

We can't wait to welcome you into the icy depths!

Today Subnautica released on PlayStation & Xbox One. Obviously, given this is Steam, that's not the most exciting news to post here. But this is a big day for us, and we owe you a big thank-you.

We've never released a game on consoles before. It's a terrifying new world. Without you, our wonderful community of players on Steam, we never would have been able to release Subnautica on Xbox or PlayStation.

Those of you who played Subnautica through Steam Early Access, and then throughout launch, provided all the feedback, bug reports, and support that allowed us to build a solid game. Without that, console release would have been out of the question.



You put up with awful frame rates, countless horrible bugs, and long, long wait for release. Thank you.

If you would like to add a console copy of Subnautica to your collection, check out the purchase options at unknownworlds.com.. We'd appreciate any retweets on Twitter or shares on Facebook you think appropriate. If you have friends or family who play games on consoles, we hope you might let them know that PS4 and Xbox options are now available.

Even as we release on consoles, we are cranking full steam ahead on Below Zero. Below Zero is a stand-alone expansion to Subnautica, a new chapter of adventure in a frozen, arctic region of Planet 4546B.

We never like to talk dates. Game development is super unpredictable, and if we gave you a date, we would inevitably disappoint. We are very much looking forward to offering Below Zero in Early Access. Our plan is to release in Early Access as soon as we have a few solid hours of arctic gameplay.

In the mean time, stay tuned and we'll keep you updated on Below Zero's progress.
