Subnautica 2 is an underwater survival adventure game set on an all-new alien world. It is the next chapter in the Subnautica universe, developed by Unknown Worlds.
Driven from your home by ongoing conflict, Alterra offers you the chance at a new life. But as the colony ship CICADA shepherds you and your fellow Pioneers to your new home, something goes awry. The ship’s AI insists that your mission should continue. Stranded and faced with near-insurmountable odds, you must do everything in your power to survive. The future of humanity on this world is in your hands.
PLAY ALONE OR WITH FRIENDS
Subnautica 2 is being crafted as a single-player experience that you can optionally play in online co-operative multiplayer with up to three friends. You can choose from four pre-designed characters, with more characters and customization options coming throughout Early Access. Work together to explore long-forgotten ruins and learn to adapt to a planet that might not want you there.
ADAPT TO SURVIVE
To survive the depths and make this planet your home, you’ll need to utilize all the tools at your disposal. Traverse vibrant and breathtaking biomes with your Tadpole submersible. Design and customize bases to return to when your adventures push you beyond the safety of shallow waters. As Early Access develops, so too will your array of tools, equipment, and vehicles. Upgrades will help push you beyond your boundaries and unlock the secrets of this strange world.
EXPLORE THE UNKNOWN
Scan and study a rich world of biodiversity to understand life here. Discover everything from the smallest creatures to towering Leviathans. Experience the wonder, and sometimes danger, lurking around every corner. Every dive is an opportunity to uncover why the ship's AI is so determined to continue the mission and what mysteries lie beneath the surface of this breathtaking new frontier.
DESIGNED FOR EARLY ACCESS
Subnautica 2 is an Early Access title in active development. Throughout this journey, we will continuously expand the world with additional biomes, creatures, and craftables, while expanding the narrative. You may encounter bugs, in-development features, and performance issues. Your feedback is the cornerstone of our development process. Join us and help shape the next chapter of the Subnautica universe.
CRAFTED BY UNKNOWN WORLDS
Subnautica 2 is being developed by Unknown Worlds, the studio behind the award-winning Subnautica and Subnautica: Below Zero. Our journey began with the 2003 Half-Life mod Natural Selection, and today we have evolved into a fully remote, globally distributed team spanning from the United States to the United Kingdom, France, Australia, and beyond. Defined by a philosophy of open development and over a decade of community-focused innovation, we invite you to dive back into the depths with a studio dedicated to pushing the boundaries of the survival genre.

THE GAMEQ VERDICT1,300 reviews analyzed
What players are actually saying
1. Summary
83.8% of this sample recommends Subnautica 2, and the praise centres on the core of the series: a beautiful, unsettling alien ocean, creatures that feel alive, a base-building system several reviewers call the best the series has had, and co-op: about one review in ten mentions playing with friends, partners or family. Some fans call it the true successor to the first game and better than Below Zero, and the story's mystery (NoA, the World Tree, reprinting) has others hooked.
The main frustration is that there is not enough game yet. Players report finishing the early access story in anywhere from under 7 hours to about 40 on a small, fairly linear map, and thin content comes up in 34% of the negative reviews, often with anger that months of updates brought fixes, voice chat and emotes instead of new biomes or story. Two other debates run through the reviews: whether being unable to hurt or properly fend off hostile creatures is bold design or a broken survival loop, and whether the game runs acceptably on mid-range and older PCs. Some recommending reviews carry a caveat about how much is missing ("it's still in early access so i'll give it time").
2. What keeps coming up
What players praise
A beautiful, immersive oceanHigh
The visuals draw more praise than anything else in the reviews. Players describe the world as stunning, "jaw droppingly pretty" and a big step up from the earlier games, with bioluminescent nights, reefs full of life and a strong sense of scale. Many tie this to atmosphere: the loneliness of open water, the dread of a dark trench, sounds from things you cannot see. Some negative reviews still concede the game is gorgeous. A couple of veterans dissent, finding the Unreal Engine look glossier and brighter than the original's rougher style ("Everything looks glossy, smooth, with a lot of bloom"), which they say makes the ocean less frightening.
Co-op finally comes to SubnauticaHigh
Co-op is the big new feature, and reviewers describe playing with partners, spouses, siblings, kids and friend groups. The stories are vivid: friends screaming when a leviathan attacks, shared bases, one player building while another explores. Short reviews say it plainly ("Very fun with friends"). Some who use the proximity voice chat added in an update call it "really fun". Some note co-op dilutes the series' isolation, and a few solo players feel the game (the Tadpole and its passenger seats in particular) is tuned more for groups. Technical rough edges in co-op are covered under frustrations.
Freer base buildingMedium
Base building comes up more the longer people played, in 11% of reviews from players past 50 hours against 2% from those under 10, and several reviewers call it the best in the series ("Base building is better than ever"). Players like the freer modular system, crafting straight from storage lockers, no hull-integrity babysitting and the metal farms. Their wishlist: stairs and multi-floor rooms, round rooms, aquariums, more furniture and decoration, and fewer prime building spots occupied by story bases. A handful find the system janky (stuck deconstruction, moonpool quirks) or less stylish than the original's set pieces.
Story, lore and voice actingMedium
Story comments lean favourable. Players call the premise fresh ("The story is a unique premise"), are drawn in by the mystery around NoA, reprinting and the World Tree, and one calls the current ending "a great cliffhanger". The few comments on the voice acting are mostly praise. Critics make specific points: the story is told through long logs and dialogue instead of discovery, NoA keeps steering you with waypoints, some plot beats retread the first game, and one found it "very nihilistic". Players on both sides want more of it.
Creatures and leviathans that keep you tenseMedium
Reviewers love the alien fauna and the way creatures react to the player and to each other. The Collector Leviathan comes up in 23 reviews, often as genuinely terrifying, particularly on a first crossing or at night ("10/10 would scream like a little girl over a psychic squid monster again"); one reviewer calls the game a "thalassophobia simulator". Series veterans counter that the early access build has only two leviathan types, the Collector's patrol pattern is easy to learn, and hostile creatures rarely feel lethal once you know the tricks.
Quality-of-life upgrades over the originalLow
Players who know the earlier games often list small improvements: crafting from lockers, big resource nodes instead of chipping outcrops, the resonator for gathering, air pockets in caves, a story reason for respawning, and a more polished early access build than either predecessor launched with. One says these features make it "hard to go back to the original".
Where players are split
How it measures up to the first SubnauticaHigh
Comparisons with the earlier games come up more than any other topic, and they cut both ways. Some call it the real sequel, better than Below Zero and, for a few, already better than the original. Others say it is a smaller, safer copy: fewer biomes, depth capped around 450 to 500 metres, one vehicle, no Cyclops or PRAWN suit, recycled plot ideas and less mystery ("Not really better than the first game yet"). The difference seems to come down to expectations: players who wanted more of the same tend to be delighted, while those who wanted the original's scale and freedom feel short-changed.
Being unable to hurt or properly fend off creaturesMedium
Hostile creatures can attack and sometimes one-shot you, but nothing in the game can harm them, and players call the available deterrents (flares, the sonic resonator, stun tools, a stealth biomod) weak. 29 reviews complain that they can't fight back, hurt or defend themselves, and 9 of those still recommend the game; one calls it their "one big issue". Critics call it immersion-breaking in a survival game where you can still eat small fish, and complain about constant harassment by needlers and similar pests while gathering. A few defenders answer that Subnautica has "NEVER been about combat". A middle group asks for better non-lethal deterrents, or an optional mode with defensive tools, instead of full combat.
Performance and hardware demandsMedium
Reports diverge by hardware. Some players say it runs smoothly and looks great on recent cards, and several note performance improved over the summer and that it works well on Linux, Steam Deck and handheld PCs. Others say it is unplayable on older or budget PCs and laptops, that it effectively requires upscaling, that VRAM demands lock out many laptops, that frame rates drop as bases grow, and that FSR 4 support is missing. Players who stopped before two hours raise these problems most: 19% of their reviews mention performance or crashes, against 6% from everyone else.
Is it worth the early access price?Medium
Opinion splits on how people value hours. Some recommending reviewers call the roughly $30 price fair or a steal for 15 to 30 hours ("I'm having fun and don't regret"), and some bought it in a bundle or on sale. Negative reviewers argue it is too much for a few hours of story with no firm date for more ("it was full price and unfinished with no release in sight"). A middle view is to wait for 1.0 or a sale.
Too easy and too guided, or welcoming?Low
Some veterans say survival is trivial: food and water are easy, oxygen bubbles are everywhere, reprinting makes death cheap, predators bite once and leave, and NoA's waypoints remove the need to explore. Some want a harder mode. Newer players can find the game confusing instead, and a couple say they needed a wiki to find key resources, while a few casual players are glad it is forgiving. A few reviewers also ask for a middle difficulty that removes hunger and thirst without going full creative.
The Tadpole as the only vehicleLow
The modular Tadpole has fans, especially in co-op where passengers keep their oxygen, but several reviewers miss the Cyclops and PRAWN suit, call the haul chassis painfully slow, find the vehicle ugly or sluggish, and dislike that leviathans toss it around. Some assume more vehicles are coming.
What frustrates players
Not enough content yetHigh
Thin content is the most common complaint in the negative reviews (34% of them raise it). Players report finishing the early access story in anywhere from under 7 hours to about 40, and describe a small, linear map where biomes feel like thin slices with empty space between them, a red barrier that kills you at the edges, few leviathans and reused shipwreck interiors. Players with 25 to 50 hours raise it most often (15% of their reviews), saying they "finished everything" and have nothing left but grinding. Plenty of positive reviews make the same point and accept it as part of early access.
Slow pace of updatesMedium
This complaint is tied to thin content and angrier in tone. Reviewers say months passed after the May launch with bug fixes, quality-of-life tweaks, a charity tie-in, an emote wheel, proximity voice chat and shared backpacks, but no new biome or story chapter, and no clear date for one ("Updates virtually non existent"). Some compare the pace unfavourably with the first two games' early access and with other early access titles.
Crashes and failure to launchMedium
Some players cannot get the game to start or keep it running: crashes on boot or at character select, an error loop telling them "you maybe exited the game wrong", black loading screens, crashes every few minutes, and in a few cases corrupted saves (notably on the experimental branch). Some fixed it themselves by turning off motion blur or DLSS or changing settings; others say they tried everything and can no longer get a refund. Crash reports come disproportionately from the shortest-playtime reviewers.
Progression bugs and rough edgesLow
Some reviewers call the build stable or polished for early access, but others hit serious bugs: story events that never trigger, angel combs that cannot be broken, generators that cannot be repaired after reloading, items falling out of reach, and lost save files. Smaller issues recur too: subtitles not matching audio, lighting flicker in bases, an oxygen warning that plays when it should not, and pieces that cannot be deconstructed.
Getting lost: no map, sonar or quest logLow
Newcomers and veterans both ask for navigation help. Players say it is easy to lose your Tadpole, your friend or your story thread, that toggling off a signal can leave you stuck, that night and dark depths are near pitch black without sonar, and that the scanner room only points to a rough area for one resource at a time, which one reviewer calls a "biiiiig downgrade" from the original. Requests include an optional map or minimap, sonar, death markers, a quest list and more scanner range.
The EULA and license termsLow
An external issue, concentrated in reviews written around launch: license complaints appear in 7% of reviews written before mid-August and under 1% of those written after. Players objected to a forced acceptance screen before they could keep playing, terms describing the purchase as a revocable license, limits on content creation and multiple devices, and data collection. Some reviewers note the terms were revised soon after launch, and one changed their review to positive when that happened, but a few still cite it as a reason not to buy.
Co-op frictionLow
Players list specific multiplayer annoyances: the host opening their PDA pauses the game for everyone, friends can take items from your backpack with no way to turn it off, connecting to friends sometimes fails, story audio logs misbehave when players are far apart, there is no text chat, and a few groups report heavy lag regardless of who hosts.
Leviathan chase musicLow
A few players ask for the music that plays when the Collector Leviathan hunts you to be removed or made optional, saying it kills the eerie silence the series is known for and announces danger too clearly.
3. The player conversation
The conversation is warm but impatient. Short reviews are almost all enthusiastic ("peak", "fish", "Very fun with friends"): reviews under eight words are 93% positive, against 63% for those over 150 words, where the detailed criticism lives. The arguments are over whether to judge an early access game by its quality or its quantity, whether you wanted the original's freedom to fight back, and whether your PC can run it.
Reviews written in launch week in May 2026 were 75% positive and carried the launch-era grievances (license terms, performance, the no-combat decision). The large wave written from late August through September ran between 83% and 89% positive, though, as the corpus note says, the older reviews in this sample lean toward ones their authors later edited to add a complaint. License complaints nearly vanished in the later reviews (7% of those written before mid-August, under 1% after), performance complaints fell by more than half, and thin content stayed the most common complaint.
4. What the developers could do
- Ship a substantial content update with new biomes and the next story chapter. Thin content is the most common complaint in the negative reviews, and players who finished the early access story say there is nothing left to do but grind.
- Publish a dated roadmap for content, not just features. Reviewers say what hurts is not knowing when the story continues, after months of updates without new areas.
- Give players effective non-lethal ways to deter hostile creatures, or an optional mode with defensive tools. The no-harm design draws complaints even from players who recommend the game, and players call flares and the resonator too weak against needlers and leviathans.
- Fix launch failures and crash loops, and widen hardware support. The "you maybe exited the game wrong" loop and boot crashes hit players in their first hours, and players on older PCs and laptops ask for lower VRAM demands, better low settings and FSR 4.
- Add navigation aids: an optional map, sonar, a quest log and a stronger scanner room. Newcomers get lost and stuck on story steps, and veterans call dark waters without sonar and the one-node scanner a step back.
- Smooth out co-op: no host PDA pause, private storage, more reliable joining. Co-op is the headline new feature, and these specific annoyances keep coming up from groups who otherwise enjoy it.
- Offer difficulty options in both directions. Veterans want a harder survival mode with real danger, while others ask for a mode without hunger and thirst that is not full creative.
- Let players turn off the leviathan chase music. A few reviewers say it undercuts the quiet dread they bought a Subnautica game for.
