Several weeks have passed since the Seamoth Update, and Subnautica development continues at full speed. Major updates are arriving on a roughly monthly basis at the moment. While it will be a few more weeks until the next update, now is a great time to take a peek at some of the sweet underwater gameplay being worked on behind the scenes.

Not everything you read about in this post will make it into Subnautica. Throughout the development process, ideas come and go, concepts are favoured then discarded, and gameplay mechanics iterated upon. Some of what is on show here may end up in an update some time in the next few months, and some might never be seen again!…

Since Steam launch in February, we have been prototyping potential Subnautica expansions, working on Xbox One launch, and working on tidying up some of the more glaring bugs in the Steam 1.0 release.

Today we released an update that includes a bunch of that tidying up. Update 84 is available on Steam and Xbox One. Here’s the list of changes:

• Main menu button texts update correctly when switching languages
• In-game menu button text colors fixed
• F8 panel fully translated
• Cyclops flooding leak indicators now clearly outside of the hull
• Controller navigation and selection boxes fixed
• Builder menu usable with swapped mouse buttons
• Lifepod fabricator lighting fixed
• Cyclops hatch door collider fixed
• Disallow poster placement where wall lockers are disallowed
• Non-localized

The Ghost Update has been released on Steam! Cure the Infection, disable the Precursor Array, command an upgraded Cyclops, and escape Ghost Leviathans! See the update in action on the Ghost Update site.

Infection Cure

Baby emperor leviathans aren’t just adorable. They’re serving up dollops of infection cure: Go ahead and grab one!

Array Deactivation

Now that you are cured, it is possible to deactivate the mighty Precursor Array.

Ghost Leviathan

Cures, Array deactivations… It can’t be all good news, can it? Nope. Ghost Leviathans now prowl the deep: Lost River, Grand Reef, and the Void are their hunting grounds. We do not recommend a close encounter with these immense, aggressive creatures.

Lifepod Exit

Subnauts will experience fancy …

There’s something in the water. It has infected this world. It has infected you.

The Infection

Some creatures are displaying symptoms of an infections disease. What is it? And could you contract it yourself?

Research Facility

Something terrifying was being done here. And something went horribly wrong.

Containment Facility Exterior

A giant structure has appeared deep beneath the ocean floor. For now, we’re just teasing: You can only explore the exterior, and will have to wait for a future update to see inside…

New Biome: Crag Field

Where there was previously empty seabed, the Crag Field has arisen. Explore this new environment, but watch out …

The latest and greatest technology in the world of Subnautica is the Map Scanner room. These rooms can be built on to existing habitats, or can stand alone. Map Scanner rooms will scan nearby seafloor, searching for a select array of resources. Additionally, there are two exterior cameras that can be piloted remotely. Upgrades bring additional benefits.
