About Subnautica
Subnautica is an underwater adventure game set on an alien ocean planet. A massive, open world full of wonder and peril awaits you!Dive Into a Vast Underwater World
You have crash-landed on an 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 diving gear, lights, habitat modules, and submersibles. 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.
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.
Warning
This game contains flashing lights that may make it unsuitable for people with photosensitive epilepsy or other photosensitive conditions. Player discretion is advised.
How much does Subnautica for PC cost right now?
Subnautica for PC starts at €1.34 (€1.64 with fees) at Key4Games, 95% under the €29.99 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €3.78 (€4.66 with fees) at Gamivo.
That €1.34 (€1.64 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.
With 39 offers across 17 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 31% under its average of €7.08 since 2017, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Subnautica now or waiting?
That €3.78 (€4.66 with fees) key is at one of its best prices.
- Those €3.78 (€4.66 with fees) are 67% below what it usually costs, measured on the store price.
- 15 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
- Not counting today, only 47 days out of the 2,526 days on record were this cheap or cheaper; the lowest it has ever cost is €3.80.
Worked out from 4,977 daily records of the Steam Key for Subnautica across 30 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Are these stores safe to buy Subnautica from?
Worth knowing before you click: Key4Games is cheapest at €1.34 (€1.64 with fees) but has only 37 Trustpilot reviews behind it. If that thin track record bothers you, Difmark has the same shared account at €1.67 (€1.75 with fees) with 14.2k reviews and a 4.1 out of 5.
Which Subnautica format should you buy?
With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Gamivo costs €2.44 (€3.02 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 13 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate Subnautica in US?
26 of the 39 offers work on US — the Global ones plus the ones issued for your own region.
Is Subnautica worth it?
55 outlets reviewed it and it averages 84 out of 100, with 92% recommending it.
Why is there such an expensive Subnautica offer?
One listing is worth ignoring: the Steam gift that Kinguin has at €44.99 (€48.92 with fees) is more than 29 times the cheapest offer and is not what this game costs. The number to work from is €3.78 (€4.66 with fees) at Gamivo.

What do our users think of Subnautica for PC Digital?
Explore an oceanic alien world—find and build bases, and craft gear—while going about the mysteries beneath the waves. On top of the water, it's serene. But as you venture in the deeper sections of the sea, suspense and terror start kicking in. Before anything else, if exploration and survival coupled with some chill vibes and sudden terror are your things, then this is your best call.
Subnautica places you right at the heart of the alien ocean of Planet 4546B as the ultimate survival-horror setting. All you get is helplessness and your plumbing tools, base-building underwater, and going further into abyssal unknown leviathans prevail. The apocryphal art of luminescence comes beyond wondrous, yet drama and terrifying sound mix to give equal measure of awe and dread. The weird mixture of horror and wonder-always under no circumstance look back!
Great game! simple as that. Beautiful enviroments, fun base building and crafting system and interesting story. I highly recomend everyone give it a try.
It's an incredibly good game. I got it free from Epic games. It's free to keep, but the 100% sale only last till 12/28/2018. Anyways, thanks to that I got the pure pleasure of experiencing the game, I look forward to seeing the next game.
