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:

Eye Candy Update



Get those eyeballs ready, Subnautica has received a massive graphics overhaul. This is the Eye Candy Update: Subnautica has never looked so good.

https://www.youtube.com/watch?v=dPMi0Zqfqow

A host of new graphics options are available in the main menu:

  • Chromatic aberration
  • Bloom
  • Lens artefacts
  • Dithering
  • Motion blur
  • Colour grading
  • Depth of field

All together, these options revolutionise the way Subnautica looks. You can mix and match all the options, and adjust their intensity, to find a look that you like best.



Eye Candy isn’t just a pretty face. This update contains a disgusting quantity of bug fixes – Over 250 at last count. In particular, we think we have solved the perennial and infamous drifting lifepod problem.



Miners among you will be happy to hear that your life just go easier. When piloting the prawn, drilled resources will automatically be placed into your inventory.



One big graphics improvement is actually a bug-fix in disguise. Sun-shafts are now properly hidden by shadows. This used to be a big problem inside bases, particularly ones with long corridors.



Eye Candy is not just candy for your eyes: Your ears are also in for a treat. Abandoned bases now feature voice-overs from new voice actors. Have a listen, and learn about what happened to this underwater world.



Speaking of bases, the Scanner Room user-interface has received some serious TLC. It is much easier to use, and more powerful, and won’t show items that have been picked up.



Who likes stargazing? We do! Problem: When stars shine through planets, stargazing becomes weird. Stargazing in Subnautica is no longer weird: We’ve fixed up a bug that caused stars to shine through orbiting bodies and clouds.



The dive-reel has always been a little bit of an oddball item. The intention is to, like a real dive reel, lay a trail that a diver can use to retrace their path out of a confined space. Unfortunately, the reel hasn’t worked so well in practice. So we’ve replaced the cord with breadcrumbs of light. We’re still working on the final effects, but the gameplay change is here now.

Cuddlefish Update



Prepare for love, cuddles, and tentacle high-fives: the Cuddlefish Update has been released on Steam!

https://www.youtube.com/watch?v=PENv0CLQoSA

The Cuddle Fish is an adorable companion creature. You may find Cuddle Fish eggs hidden around the world. Those eggs can be incubated in an Alien Containment module, and will eventually hatch into a Cuddle Fish.

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.

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.
