    The story in Subnautica 2 is engaging and atmospheric, offering a darker, more complex narrative than its predecessors, with well-developed lore that rewards exploration and discovery. While currently incomplete due to early access status, it provides a solid foundation and intriguing mysteries that captivate players, though some find it confusing or overly guided. Players appreciate the immersive storytelling integrated with gameplay, despite wanting more content and clearer progression in future updates.

    • “The atmosphere is amazing, the leviathans are terrifying, the story and world building is fantastic.”
    • “The story, though still far from complete, is extremely compelling, providing a mystery narrative far wider in scope than found in the original game or below zero and with more nuanced storytelling, leaving it largely up to the player to decide what to make of the clues they find.”
    • “Having played up to current early access 1.0, i gotta say that the story and characters are fantastic with a deep and immersive plot that makes you feel part of the world.”
    • “They give a weak, gamey explanation why Alterra took away the weapons, which tells me the devs intentionally took away my ability to defend myself and tried to work that into the storyline; it's not just because of early access.”
    • “The story is weak and minimal; the map is tiny, and things that are supposed to interact with you do not work, so you can't complete the story.”
    • “Being early access, the story is not fully done yet, and it ends abruptly with a 'thank you' message, which leaves a cliffhanger feeling and frustration.”

    Subnautica 2 delivers stunning, immersive visuals with a significant graphical upgrade over its predecessors, characterized by realistic lighting, detailed underwater environments, and vibrant biomes that greatly enhance the atmosphere and exploration experience. While the graphics are widely praised for their beauty and contribution to the eerie, captivating ambiance, the game is also noted to be quite demanding on hardware, often requiring mid to high-end PCs to run smoothly, with some ongoing optimization issues and graphical glitches expected due to its early access status.

    • “The visuals are absolutely stunning, the creatures are both beautiful and terrifying, and the underwater world feels alive in a way very few games can match.”
    • “The game has incredible graphics and scenery, the creatures are very well designed in both appearance and behaviour with some exceptions.”
    • “Simply put, if it conflicts with another form a law, theres usually a case to fight for it in court if krafton decided to say "♥♥♥♥ you, thanks for the free art work".”
    • “The graphics are washed out, and there's no FOV adjustment, forcing you to play with your face glued to the screen.”
    • “The optimization is terrible; even at the lowest graphics, my PC can't reach 50 FPS and suffers from frequent drops.”
    • “Runs poorly even on low graphics settings, worse than the original Subnautica, despite being built on Unreal Engine 5.”
  • gameplay

    Subnautica 2 offers a polished and immersive gameplay experience that builds upon the original with improved base building, new mechanics like genetic adaptations and biomods, and cooperative multiplayer. The core loop of exploration, resource gathering, and crafting remains engaging, with enhanced visuals and smoother controls, though some find the pacifist approach to hostile creatures limits player agency and may reduce tension. Despite early access limitations, the game currently provides around 10-20 hours of solid gameplay with room for further polish and expanded content.

    • “The core gameplay loop that involves exploration and crafting up to ever-greater capabilities remains at the core of the game.”
    • “The gameplay is an enhanced and more refined gameplay from Subnautica 1 and Below Zero, with new tools, more flexible base building, and much quality of life addition such as material automatically taken from storage when crafting.”
    • “The gameplay loop is a deeply satisfying return to form for the Subnautica series and, dare I say, made even more enjoyable by the quality of life improvements made by Unknown Worlds.”
    • “The monster AI seems to be built around a cat-and-mouse gameplay style, but things like the marrow breach only dealing 5 damage, or the collector leviathan's area being so wide and open with almost no hiding spots, completely undermine that idea.”
    • “This is just an underwater basebuilding game, nothing else: horrible and boring story, horrible pacing, horrible gameplay loop, absolutely nothing about this game is scary; the aggressive fish being invincible makes everything so boring and absolutely annoying as hell to deal with.”
    • “The game is not hard, and it's a great game for being early access. However, the ability to fight off predators has already been denied by the devs who decided to remove the mechanics from the two previous games and made the protagonist a sitting duck, openly not planning on changing this aspect of the game.”
  • optimization

    Optimization in Subnautica 2 is a mixed bag: while many users praise its surprisingly smooth performance and solid stability for an early access UE5 game, others report significant issues including frequent frame drops, stuttering, and high hardware demands even on mid-to-high-end PCs. The game often requires upscaling technologies like DLSS or TSR to achieve playable frame rates, especially at higher resolutions, and base building and multiplayer can cause notable performance degradation. Despite these shortcomings, the developers are actively working on improvements, with optimization expected to improve significantly by full release.

    • “Runs very well for being early access, feels more optimized than sub1.”
    • “Stable performance.”
    • “Performance is honestly really good for an early access game.”
    • “This game might be good, but the performance is really awful (60fps max) and even if I set max fps to 30, the game still has huge fps drops to 10-15fps every minute or so.”
    • “Great game I have been playing on a GTX 970 with consistent 40 fps very optimized game and it's Subnautica..”
    • “The game is very poorly optimized right now so you have to have a decent PC to get okay frames, I only average 70 frames on medium settings.”
  • stability

    Subnautica 2's early access release is surprisingly polished and stable compared to typical early access games, with generally smooth performance and minimal game-breaking bugs. While some minor glitches and occasional crashes occur—especially in multiplayer and base building—the overall experience remains enjoyable and well-optimized, with many players reporting far fewer issues than expected. The developers actively address bugs and the game's framework shows strong promise for further refinement ahead of full release.

    • “For just being in the first stages of early access, the game runs great with almost no bugs so far.”
    • “The game runs well with no fps drops, no freezes or softlocks, and no crashes so far.”
    • “Very polished so far with nearly no glitches; many great upgrades to things like base building and crafting from previous versions that make things much better.”
    • “If you want a full no bug game then wait about a year or two for 1.0 or at least until most major bugs are fixed as it is incredibly buggy and laggy as of now.”
    • “Super buggy very disappointing, unplayable.”
    • “The bugs and glitches make this game flat out unplayable at times.”
  • music

    The music in Subnautica 2 is generally praised for its ambience and atmospheric fit, with many enjoying the soundtrack's integration into the game’s environments and tension-building elements. However, a common criticism is the inclusion of "boss" or chase music that plays whenever leviathans are nearby, which many feel removes the surprise and fear factor by alerting players prematurely, thus diminishing immersion and the original game’s sense of suspense. While the soundtrack is considered good and sometimes phenomenal, several reviewers note it does not quite match the uniqueness, emotional depth, or memorability of the original Subnautica’s music.

    • “The soundtrack is phenomenal, beautifully underscoring the open ocean with a fantastical sense of wonder and emphasizing the looming void and its creatures.”
    • “The sound design and music perfectly complement the experience, making every journey memorable with atmospheric, terrifying, and immersive audio that greatly enhances the game.”
    • “The music that plays when near a leviathan is a brilliant touch that adds intense emotion and dread, giving these creatures a powerful presence and elevating the horror aspect of encounters.”
    • “The constant boss music when a leviathan is nearby ruins the surprise and suspense, making the encounters less scary and more like a warning system rather than an intense thrill.”
    • “The music and chase themes that start playing long before seeing the collector leviathan take away the fear of surprise attacks, turning tense moments into predictable events.”
    • “Compared to the original subnautica, the soundtrack feels generic and less atmospheric, lacking the eerie, alien quality that made the first game's music so memorable and impactful.”
  • atmosphere

    The atmosphere in Subnautica 2 is widely praised as immersive, tense, and beautiful, successfully capturing and even enhancing the eerie, underwater environment vibe that made the original game so memorable. While some reviewers note that the horror elements and creature aggression are slightly toned down compared to the first game, the combination of stunning visuals, sound design, and worldbuilding creates a captivating mix of awe and dread. Overall, the atmosphere remains the game's strongest and most compelling feature, balancing mystery, exploration, and survival in a deeply engaging underwater setting.

    • “The atmosphere, exploration, and overall feeling that made me fall in love with the series are all still there, and I can’t wait to see how the game evolves further.”
    • “The atmosphere is absolutely incredible, beautiful, mysterious, and genuinely immersive in a way very few survival games can pull off.”
    • “From the very first minute, the game creates an atmosphere that is both breathtakingly beautiful and genuinely terrifying.”
    • “Subnautica 1 really nailed the atmosphere, here it's not there yet.”
    • “The music is worse and the atmosphere is just lacking.”
    • “- weak atmosphere that doesn't make your spine get chills like in the first game (an example, the sole existence of the aurora was enough to engage you into the story and tell you what's at stake, the gravity of the situation. sub2 doesn't is way weaker at embracing you with those story elements); even if you were experienced in subnautica 1, most of the time the fear factor was always there thanks to multiple atmospheric elements which are lacking here.”
    • “The game's atmosphere feels thin and too easy.”
    • “Animals are invulnerable, and the aspect of defending yourself or even simply observing the cycle of life with how fragile death is has created an atmosphere that feels less grounded than the original.”
    • “The soundtrack never reached the atmosphere or emotional highs of the original game for me.”
    • “If you are looking for a similar experience as s1 when it comes to the tone and general atmosphere, this is not it.”
    • “The atmosphere definitely feels more bland and empty than the first game.”
  • humor

    521 mentions Positive Neutral Negative
    99% positive mentions, 0% neutral mentions, 1% negative mentions

    The humor in the game is often highlighted through amusing bugs and glitches that, while present due to the early access state, add a lighthearted and entertaining layer to gameplay. Players frequently enjoy funny multiplayer moments, quirky creature behaviors, and the game’s dark, sarcastic tone woven into its story and dialogue. Overall, the humor complements the game's spooky atmosphere, making it a fun and memorable experience, especially when shared with friends.

    • “The co-op is super fun and goofy with friends, and honestly every bug I’ve run into so far has just led to funny moments instead of ruining the experience.”
    • “I've been playing it almost fully in multiplayer with 1-2 friends and it's such a fun experience full of laughter, screaming, 'oh hell no, I'm good' and 'omfg let me drive the damn tadpole' — we have sunk over 30 hours into the game and have not reached the end of the currently playable story, but what we have seen so far has been captivating, creepy, sad, funny, and downright scary.”
    • “Even in multiplayer I haven't experienced any game breaking bugs, just funny ones like rebreathers letting you give tadpoles superspeed.”
    • “The ship computer and PDA logs contain a plethora of desperately unfunny 'if you're reading this you're underwater - this is bad for humans' type jokes every ten seconds.”
    • “It's not funny when you're 150m deep and you hear what feels like the biggest thing in existence behind you.”
    • “The location where we build our base near the safe shallows had annoying critters that barraged me after leaving the base for just a few seconds. That was not funny.”
  • grinding

    484 mentions Positive Neutral Negative
    2% positive mentions, 9% neutral mentions, 89% negative mentions

    Grinding in the game receives mixed feedback: many appreciate quality-of-life improvements that reduce tedious inventory management and resource gathering compared to the first game, with base building and farming considered enjoyable by some. However, persistent issues like lack of item stacking, frequent backtracking, slow vehicle movement, inventory limitations, and unkillable aggressive creatures contribute to a monotonous and tiresome grind, especially in late-game stages. Overall, while the progression generally feels natural and engaging, the grind can become excessive and repetitive, making the experience less immersive for some players.

    • “The progression feels steady but not too fast, and slow enough to make you feel accomplished after obtaining something you have been gathering resources for the past 30 minutes but not too tedious as to make you want to stop playing.”
    • “Gathering and crafting are just challenging enough to be fun and not grindy.”
    • “The gameplay overall as a survival game isn't tedious at all.”
    • “The fact that they still haven't added any sort of item stacking in this game is beyond ignorant and makes the game a tedious grind. "Oh, I got a new blueprint to make these absolutely terribly slow arm jet things that aren't nearly as good as the seaglide from SN1, I better go out and fill my inventory with 5 items so I can make this one item" and then within 2 minutes of use "Oh now I have to go and build batteries, oops I'm out of resources because nothing stacks, I better go and get more so I can come back and be able to build two batteries with a full inventory worth of items."”
    • “Inventory limitations, long travel distances, depth restrictions, oxygen management, hostile creatures, and long farming timers all combine to slow down the pace.”
    • “It breaks immersion for a lot of folks, but it also just makes the game overall much more annoying and tedious.”
  • emotional

    The emotional experience of the game is deeply polarizing, with many players praising its ability to evoke strong feelings of fear, awe, isolation, and nostalgia reminiscent of the original Subnautica. Some find the story and atmosphere richly emotional and immersive, creating a profound connection to the world and creatures, while others criticize the pacing, lack of fear, and uninspired voice acting as detracting from emotional engagement. Overall, the game excels in generating emotional highs tied to exploration, environmental tension, and survival, though these moments can be uneven and sometimes undermined by gameplay or narrative issues.

    • “Subnautica 2 succeeds not merely as a survival game, but as an emotionally heavy sci-fi drama that meaningfully improves on its predecessors.”
    • “The story, even in its current incomplete state, hits harder emotionally than Subnautica 1 and feels far more human, while also being more coherent than Below Zero.”
    • “That emotional transition from wonder to fear is something the game masters perfectly over and over again.”
    • “This is just an underwater basebuilding game with nothing else. The story is horrible and boring, pacing is terrible, and the gameplay loop is dull. There's nothing scary about it, and the aggressive fish being invincible makes everything frustrating and annoying to deal with.”
    • “Here, you sit in the newbie area listening to their boring story and progress at their pace, unlocking the story in the order they want. It's all only done one way.”
    • “The map is very empty, monsters aren't a threat at all, and the game has a boring story.”
  • replayability

    88 mentions Positive Neutral Negative
    22% positive mentions, 64% neutral mentions, 14% negative mentions

    The game's replayability is currently mixed, with early access providing around 8-15 hours of engaging content, largely centered on exploration and base building, especially enhanced by multiplayer co-op. However, many users find the story linear and limited, with a lack of procedural variety, difficulty modes, and long-term goals reducing replay value once the main content is completed. Future updates, added biomes, expanded story, and multiplayer improvements are expected to significantly boost replayability and player engagement over time.

    • “Overall, amazing early access with much replayability.”
    • “Amazing game even for early access, plenty to do and plenty of replayability, build mode can be frustrating but is very rewarding as well, the story so far is very interesting and engaging, there aren't as many bugs as I thought there would be.”
    • “10 hours deep, at a rather fast pace to progress, I can already tell this game is a true and loyal sequel to Subnautica. The content has and replayability is already off the charts with the very well made habitat builder and multiplayer.”
    • “I was done in 15 hours and there is no reason to keep playing as there is nothing left for me to do and no replayability.”
    • “Can't recommend right now just because of a severe lack of content with zero replayability; even some resources don't respawn and are completely limited, so be careful.”
    • “Unlike other games, there is little to encourage replayability -- no harder difficulty modes, no cross-run variability, and no random generated maps, limiting exploration replay value.”
  • monetization

    48 mentions Positive Neutral Negative
    6% positive mentions, 23% neutral mentions, 71% negative mentions

    Monetization in the game is controversial, with no microtransactions but extensive data collection and restrictive EULA terms that many perceive as overreaching and cash grab tactics. While some appreciate the lack of microtransactions and believe the developers care about the game, concerns remain about slow content updates, potential future monetization, and corporate control over user content and privacy. Overall, the monetization approach causes mixed feelings, balancing between genuine early access and fears of exploitation.

    • “Microtransactions / DLC: none”
    • “No hidden fees or microtransactions to play with friends like on Minecraft.”
    • “I’m so happy that it was made by a studio like Unknown Worlds Entertainment, a studio that still cares about players instead of filling their games with overpriced extra content and microtransactions.”
    • “Unfinished cash grab!”
    • “Such an early access cash grab.”
    • “Mid cash grab overhyped by people with one braincell that will eat up any pile of crap and call it amazing.”
  • character development

    10 mentions Positive Neutral Negative
    30% positive mentions, 40% neutral mentions, 30% negative mentions

    Character development in the game receives mixed feedback, with praise for solid character growth and systematic progression, as well as room for further development, particularly for specific characters like Noa. However, opinions on character design are polarized, ranging from striking and immersive to unappealing or incomplete due to placeholders or missing elements.

    • “Solid plot, good character development and plenty of room for more.”
    • “Incredible voice character development”
    • “Plot, items, gear, upgrades, character development options etc. are either missing entirely or have placeholders.”
    • “I need more character development of the Noa character, but otherwise I would say that this is a fantastic game.”
    • “The character development system and the discovery of new features are presented in a more systematic way.”
