About Subnautica
Crash-land on an alien ocean planet and survive by scavenging resources, crafting gear, and building underwater bases while uncovering the mystery of what happened to this world. Explore a vast, dynamic ecosystem teeming with both helpful and deadly creatures across diverse biomes, from sun-drenched reefs to bioluminescent deep-sea trenches and treacherous caves.
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

What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Players praise Subnautica for its engaging exploration and immersive world with memorable creatures, though some find the scary encounters off-putting. The main complaint centers on poor progression clarity and lack of in-game mapping tools, leaving players frustrated despite the game's addictive gameplay loop and the abundance of online guides available.
it ok
I loved playing this (until I had to do the scary bits) and it was one of my favorite games of all time (no Subnautica 2 bc Apple). As the random time capsule man said, "Hang tight, and don't let the reapers bite".
여름에 하기 정말 좋은 게임입니다. 하하
fishy fishy swim swim
You'll play for hours and get nowhere. That's with help videos and walkthroughs. Not clear enough progression, no maps or GPS. Can place beacons everywhere and maps published online, but no in-game ones. Once a location is scouted/scanned, it should be added to the map. Space age tech available but no map. The designers had their heads on backwards.
super good there are nice big and friendly dragon like creatures that give you item and other stuff that could be useful just go behind the behind spaceship they are located there
