What the developers have to say:

Why Early Access?

“Some games are built inside boxes. No one can see inside the box, they can't enjoy the game while it is being built, and its strength depends completely on the skill of the people inside the box. Other games are made out in the open in full view, with countless people contributing to them in innumerable ways. They can be enjoyed while they are pieced together. At Unknown Worlds, we like making games in the open. It's more fun that way, and we think it makes better games.”

Approximately how long will this game be in Early Access?

“Subnautica will most probably be in Early Access for a significant portion, or most of 2015, 2016, and 2017. There a reasonable chance that it will be longer, or shorter. Members of the Subnautica team have differing ideas about how what exactly will be done before Early Access finishes, and the scope of work to be done (and therefore time needed) will be heavily influenced by your feedback during the Early Access process.”

How is the full version planned to differ from the Early Access version?

“Early Access is a nucleus around which a better, bigger, and more fun game can form. Lots of the core elements of Subnautica gameplay are already in place. Over time the world will grow larger, deeper and more striking, creatures more diverse and intelligent, loot, crafting and vehicle construction more comprehensive, the story more fleshed out, and ecosystems richer and more vibrant . Large submarines, new unique life forms, and fantastic environments are all in production and will be introduced to Subnautica Early Access in updates.”

What is the current state of the Early Access version?

“Subnautica is absolutely playable and relatively stable right now. There are at least several hours of adventure content available for play right now, including many major story elements. A wide variety of items and vehicles may be crafted, and a diverse array of biomes explored.”

Will the game be priced differently during and after Early Access?

“Subnautica's price might go up, down, or stay the same during and after Early Access. It is most likely that we will raise the price slightly upon release.”

How are you planning on involving the Community in your development process?

“Open development is everything to Unknown Worlds. Here's how you can get involved in, influence, and be a part of Subnautica's development:

Right click on the Cuddle Fish to tell it to follow you on your adventures. Right click again to tell it to stay in one place. Left click to interact with the Cuddle Fish in various ways – It loves snacks!

The Cuddle Fish Update also includes upgrades to vehicle Head-Up-Displays (HUDs). The Seamoth, Prawn, and remotely operated cameras on both Cyclops and Scanner Room all have new HUDs.

Ghost Update Released!



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.

https://youtu.be/w4NVDF79SjE

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 new exit animations when leaving the life pod for the first time.



Power Transmitter

Since the dawn of time, simple grey polygons have represented power transmission. No longer! The humble Power Transmitter now has its very own model. Hooray!



Reaper Graphics Upgrades

Reapers like to get up close and personal. They want to look their best when they are munching on your face. Experience horrific drowning by way of vicious alien life form: Now with added texture detail!



Poop

The feature you have been waiting for. Sea Treaders now leave real poop trails behind them!



New Biomes

Explore the brand new “Mesas” biome, as well as extensive new tunnels between Lost River and Lava Zone.



Cyclops 4.0

The 4th Cyclops iteration is here. Now with:

  • Immunity against medium sized creature attach (Lava Lizards, Bonesharks, Stalkers)
  • 6 upgrade slots (up from 4)
  • No cooldown on Silent Running or Shields
  • More powerful exterior lighting
  • Larva larvae displayed on damage hologram



PDA Enhancements

New animations, visual cues, and tooltips have been added to the PDA.

Performance

Our automated performance testing indicates that you may experience approximately 9% faster frame rates in Ghost. We don’t want to make too much fuss over this: We have a long way to go. But we wanted you to know that we are working very hard on performance, and seeing measurable gains.

A Note on Saved Games

For technical reasons, we have had to reset the entire Emperor Leviathan sequence across all saved games. We always work hard to preserve saved games and are sorry to have to do this. If you saved your game inside the Prison, and now find all the doors have re-locked, you can escape by approaching the doors from the inside. They will open for you.

About This Game

Subnautica is an open world, underwater exploration and adventure game currently under construction at Unknown Worlds. The game is in advanced stage of Early Access development, with substantial content available for play. Performance/frame-rates, stability, and polish are not yet up to the standards of a finished game.

Dive Into a Vast Underwater World




You have crash-landed on 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 knives, lights, diving gear, and personal water craft. 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.
