Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

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. 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 is at least one hour of adventure content available for play right now. Before going on Early Access, Subnautica was publicly available and playable for two months. In this time, significant work was done to ensure that the game is in a state to stand up to the demands of Early Access.”

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. We don't expect it to change, but the possibility is there.”

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:

PRAWN Update Released!



This suit can handle the pressure.

A brand new vehicle is available in Subnautica: The Pressure Re-Active Waterproof Nano Suit, or PRAWN Suit. This big bipedal mech-suit is yours to command, available now on Steam.

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

The PRAWN suit is capable of diving to great depths, allowing you to explore dangerous caverns and lava fields. PRAWN comes standard with a claw arm that can be used to smash small rocks and pick up items. The suit also accepts modular arm attachments:

  • Drill Arm: Collect resources from large resource deposits
  • Grappling Arm: Fires a grapple to reel in small objects, and pull the suit towards large objects.
  • Torpedo Launcher: Fire torpedoes to defend yourself against aggressive creatures
  • Propulsion Cannon: Lift, attract, and launch small and medium sized objects

Like the Seamoth Submersible, the PRAWN suit may be docked with a Moon Pool or Cyclops Submarine for repairs, recharging, and modification.

Aurora Wreckage Expanded

Also included in the PRAWN Update: Brand new sections of the Aurora, ready for you to explore. There are a multitude of story points and items to be found amongst the wreckage.

(Micro) Update 67



Update 67 is now available on Steam. We haven’t named this update, because it is a little baby update. Unlike Farming, Power Nap, Machinery, and other updates, 67 doesn’t include any big exciting new features. It does include important and useful improvements to the game. Read on to find out what’s inside.



Subnautica now supports the use of Xbox controllers when playing on PC. You can adjust controller bindings in a new options section in the main menu. Controllers do not yet work in the main menu itself – Sorry about that, we intend to remedy this in future.



Thanks to some optimisation work we’ve done for the Xbox version of Subnautica, the game will now run slightly better on low-end PCs. If you are running Subnautica on PC at or near minimum-specification, you may notice slightly better frame-rates.



We’ve applied a blowtorch to the loading screen. It will now crash far less often on Windows. The ‘grey screen’ crash, where the Subnautica would become non-responsive and crash, was one of our most frustrating bugs. After this update, we expect you will see it a lot less often.

Also included in Update 67 are:

  • Drowning in Hardcore mode will not longer cause an endless black screen
  • Seamoth and player turn speeds are now more consistent
  • FPS command now available in console
  • VR Bugs have been squashed – you can now make a climb & use the Mobile Vehicle Bay properly
  • Locked but known technologies (e.g. Seamoth in Constructor) will display grey icons in fabrication menus

And that’s it for Update 67. To be notified when a new major update is available on Steam, sign up to the development update newsletter. We’re looking forward to bringing you the next big Subnautica update!

About This Game

Subnautica is an open world, underwater exploration and adventure game currently under construction at Unknown Worlds, the independent developer behind Natural Selection 2.

Dive Into a Vast Underwater World




After crash landing on an alien ocean world, the only way to go is down. Subnautica's oceans range from sun drenched shallow coral reefs to treacherous deep-sea trenches. 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 waking up 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.

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 unawares 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.

Go Below The Deep




Cave systems wind below the sea bed, from dark claustrophobic passages to caverns lit by bio-luminescent life. 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.

Night times, for the first time - If freaky as hell!

Have you ever swam in the ocean here on earth and felt the feeling that something is going to come and eat you alive? - Well this game literally makes me feel like that 100% of the time!

Subnautica is a first person, openworld sandbox, based in the open water-world of somewhere not earth. Overall it's not a bad game at all, personally I find that it's lacking content in-game to keep me captivated for more than a few hours.

However in saying that, the graphics and gameplay are as smooth as it is beautiful. Not only that but the atmosphere the game developers have given the game has definitly set some kind of standard, conveying a complete sense of openess. Which leaves me feeling somewhat scared at times!

This is honestly the best game I have bought/downloaded from steam. Looking around me, every single tiny thing is so beautiful. There's lots to do and lots to do discover so I could play for hours. Plus, going down into the ocean is always a chilling and amazing experience knowing that anything could be down there and also seeing some amazing sites.

I just love it. It is by far the greatest survival game ever made.

Subnautica is one of those Early Access games that has me on the fence.

On the one hand, it does a lot of things well. For example, the game's visuals are nice, and the different areas of the sea are all aesthetically appealing. There's a good deal of conveyance towards which areas are relatively harmless and which areas have giant sea-monsters that will rip you in half. In addition, I can't imagine how things would appear for the VR users, and personally I don't want to find out - the Reaper Leviathan nipped that urge in the bud. Still, the option to play the game in VR, in tandem with the already pleasant atmosphere, leaves the game with a strong recommendation from me for the visuals alone. In terms of gameplay, the game performs similarly to games like Rust or ARK, and although the crafting/upgrades system is nothing groundbreaking, it is still enjoyable and rewarding. There are certain unique aspects to the game, many of which I feel are too minuscule to even bother bringing up; however, the game does things differently enough that I feel comfortable saying that it has a personality of its own.

On the other hand, the game is in Early Access, which means that not only is it not complete, but it is still relatively unpolished. Although the game has undergone extensive changes and would appear to be updated frequently, I can't say that I've never been burned by the game due to some glitch or another. For the patient (you saints), the game's glitches and bugs are relatively harmless, and they border more on the taxing side of frustration rather than fully-fledged rage. Still, the point remains that the game could be another Early Access flop, but I'm fairly confident that it won't be. Hopefully, these issues can be ironed out, and I do believe the devs will continue to work on this project.

As it stands, Subnautica gets a mostly confident vote of approval from me, and I would recommend buying the game if it interests you (especially if it's on sale).

If you like underwater games buy this.
If you like being scared and fear underwater monsters totally buy this.
If you like being stuck in 1000m depth, running low on oxygen with a giant sea-snake chasing you, give this game your heart! 9/10

Subnautica is one of the best survival games out at the moment, and extremely good for an early access game.
Pros:
+ Massive open world with many biomes to explore, each including many unique alien plants and animals, all of which you can interact with, observe, and many times, swim rapidly away from.
+ Simple crafting system that unlocks new recipes when you find new materials and scan fragments of technology that are spread across the ocean.
+ Great base-building system, which includes a variety of special rooms with unique purposes, alien containments, power systems, and more.
+ A subtle but good story that is hidden in different abandoned bases left by other survivors who previously inhabited the alien ocean world and various shipwrecks that broke off of your spaceship when it crashed on the planet.
+ Dozens of hours of content
+
+ Subnautica has very few bugs for an early access game.
+ The developers constantly are adding new content such as biomes, different technologies, items, base accessories, and bug-fixes.
Cons:
-No autosave system, so be careful to save constantly or you may lose a lot of progress
-Occasional bugs and crashes, but nowhere near as many as other early access games.
-The short render distance occasionally gets annoying when exploring large areas.

Overall: Subnautica is a great game that I highly suggest, and I have defintely gotten more than $20 worth of content out of this, and there is still much more for me to do after 50 hours. Also, the developers are constantly adding new content, so this game will just continue to get better!

Subnautica is everything No Man's Sky is not.

The devs decided to go with a smaller yet insanely creative and colourful hand-crafted underwater world filled with life instead of a billion planets filled with nothing interesting.

This 20$ game has more content in early access than a 60$ piece of overhyped poop.

The story is presented through exploration and keeps you interested due to subtle presentation. Whereas in No Man's Sky there is only non-stop grinding and almost no story elements.

Tens of hours of content, and if you love exploration it can become a hundred (while still early-access), whereas in NMS there's like 3 hours of content and then grinding + repetition.

Inventory management is a big part of the game, however it is simple and effective (does not hinder you like in NMS).


If for any reason you thought that buying NMS was a good idea, just save yourself 40$ and buy this game, you will not regret ir. While it is an underwater, and not space exploration game, you will find everything you would want from NMS. Subnautica is a beautiful, immersive, and well-crafted world just waiting to be explored. This is by far the best exploration game you can find on steam.

Great game. Both visually and in terms of gameplay.

I was cautious when buying Subnautica as survival games as a whole have become extremely boring throughout time, however Subnautica brings a fresh survival experience for anyone who has become bored of the monotomy of the usual survival games.

On an ocean filled planet, exploring the depths should be an exciting exprience and the developers have made that so. The map is filled with very unique areas with more to come. Most of these areas require exploring due to rare resources being present or blueprint parts for building new equipment/tools.

The game is in Early Access so there are a few bugs and framerate issues in the game, but it's worthwhile noting that new content is being pumped out by the developers at an acceptable rate and bugs are being fixed, which makes it worthwhile buying into the early access.

I expect I'll manage to get a minimum amount of 25 hours of gameplay, which for £15 is a good deal !

After the $60 price tag + mediocre response scared me away from No Man's Sky, I was in the market for an open world exploration game. I found my way to Subnautica, and it has totally delivered.

I don't want to say too much, because part of the joy for me came from coming into the game with almost no information. I don't think I've been this in love with a game since I was a kid. Its tons of fun, the world is vibrant and rich, and curiosity is consistently rewarded.

Two thumbs way, way up.

For being early access, and having some bugs in the Experimental mode (obviously) this game has proven to be well worth the cost for early access. The dev team is constantly working and uploading new content as well as fixing bugs. The dev blog is wonderful and this team seems to actually really care about the quality of their finished product - unlike Hello Games >_<
