Hi Subnauts,

We’re thrilled to release an update today for Subnautica on Steam to improve compatibility with the Steam Deck.

You’ll notice that Subnautica is now marked as ‘Verified’ on the Steam Store, which means that the game should work seamlessly when you play it on the Steam Deck.

Here are some of the improvements the team made to bring the Steam Deck compatibility update to life!

• Steam SDK upgrade
  
• Steamworks .NET upgraded to 20.1.0
  
• Virtual Keyboard support for Steam Big Picture mode
  
• Fixed wrong controller stick dead zones handling (now should be easier to aim using controller)
  
• Fixed occasional black screen on game start
  
• Refactoring, other fixes and UX improvements (mostly related to controllers)
  
• Fixed black screen in VR after resolution change

We hope these changes will make your Subnautica experience on Steam and the Steam Deck even better than ever!

Keep diving,
Unknown Worlds

Hello Subnauts,

We’re delighted to bring you the long-awaited 2.0 update to Subnautica across all platforms.

This update has been a labor of love for the entire Subnautica team. As you might have seen in some of our previous blog posts, a lot of time has been spent addressing a ton of tech debt and bringing across some improved code from Below Zero.

Our goal was always to bring both Subnautica and Below Zero onto unified versions of Unity, and with today’s update, that goal has been achieved. By doing this, we’ve been able to implement several quality of life features, fix many outstanding bugs, and introduce some performance improvements that were already available in Below Zero.

We’ve also added some base pieces to Subnautica that were previously only available in Below Zero, specifically the Large Room, Glass Dome, and surface hatches. Now you can make your bases even more epic than before!

On top of these changes, we’ve also refactored and optimized our save system, which means it’s now even faster and more reliable to save and retrieve your save.
Other additions include:

• Adding the TextMeshPro plugin, to improve UI readability and visual quality
  
• Adding an ‘Unstuck’ button to the menu to help get you out of some sticky situations
  
• Bringing over PDA pause, the ability to disable light flashes, and item bars from Below Zero

As for bug fixes, we’ve closed out over 800 in total, including multiple issues related to base building (server clipping, deconstructing buildings whilst inside them), vehicle navigation and piloting.

If you’re not quite ready to move to the new update, because you’re using mods on your save file or otherwise, you can also roll back to the ‘legacy’ beta on Steam to continue playing. Just head to ‘Properties,’ then ‘Betas,’ and choose ‘legacy’ from the drop down. You should do this before you open your save file to play.

We really hope that all of these changes make your Subnautica experience even better than ever! And as some eagle-eyed fans might have spotted, we might have some more exciting news for you in the new year.

But for now, enjoy, and happy diving!

For the first time, the original Subnautica soundtrack is available to purchase from Steam.

To make the soundtrack more readily available, we've moved the soundtrack from the game itself to additional content. If you already own a copy of Subnautica on Steam, you will automatically be credited with a free copy of the soundtrack to download. You can find and download this directly from the game listing in your Steam Library.

Additionally, for the next seven days, any purchase of Subnautica on Steam will also come with the soundtrack. After that, it will be available to purchase for $9.99.

Enjoy, and happy diving!

Further detail and polish work has been added to Deep Lilypads and the Iceberg Zone. Revisit these impressive biomes to discover just how rich and vivid the world is becoming.


The behaviors of several creatures that inhabit the vast waters of the planet have been revamped with this update.

Explore and traverse the cavernous, newly reworked Glacial Basin biome. With more nooks and crannies to uncover, the Basin now merges more seamlessly with underwater experiences via Glacial Bay.

Avoiding hypothermia while exploring the surface of the planet is now a concern with the introduction of cold mechanics.
