  • gameplay
    2,943 mentions Positive Neutral Negative

    Barotrauma offers a highly immersive and complex cooperative submarine simulation experience with deep, interlocking mechanics across roles like mechanic, engineer, medic, and captain. While initially difficult to grasp due to its steep learning curve and occasionally clunky controls, the gameplay rewards teamwork, strategic crisis management, and emergent player-driven stories, especially when played with friends. Its core loop of submarine maintenance, exploration, and combat can become repetitive solo but excels in multiplayer with the added variety of mods and custom content enhancing replayability.

    • “Barotrauma's gameplay mechanics offer a satisfying level of depth and complexity. Mastering the controls and understanding the intricacies of the gameplay mechanics may take some time and patience. It may take a few attempts to grasp the mechanics fully, but once you do, the gameplay becomes incredibly rewarding.”
    • “Gameplay consists of piloting your submarine through the frozen and radiated oceans of Jupiter's moon, Europa, fighting off alien wildlife and pirate subs, exploring wrecks, and keeping the sub running and in one piece. The submarine systems, crafting, rewiring, and combat mechanics are detailed and add to the immersive experience.”
    • “The game brilliantly combines intense cooperative multiplayer gameplay, survival mechanics, and a deeply immersive submarine simulation. Every role aboard the submarine—captain, mechanic, engineer, medic, security officer, and assistant—has unique skills and responsibilities, creating a dynamic and engaging gameplay loop that demands teamwork, strategic thinking, and quick adaptation to unexpected challenges.”
    • “Mechanic and engineer are both completely negated by AI crew, turning the gameplay from fixing the submarine to sitting around the ship.”
    • “The game has a slow start, and some may not enjoy the slower style of gameplay, but this is all to make the rush of battle and everything going bad even more exciting.”
    • “Without expansions to the gameplay offered by player mods, many of the jobs are too simple and/or unexciting, and the gameplay doesn't vastly change or improve over time.”
  • story
    2,804 mentions Positive Neutral Negative

    Barotrauma offers a minimal traditional narrative focused mostly on emergent storytelling generated through cooperative submarine missions on Europa. While a campaign mode provides some lore, factions, and a broad mission structure, the story is generally subtle and secondary to gameplay, with many players emphasizing the unpredictable, often chaotic experiences shaped by teamwork, disasters, and player interactions rather than a fixed plot. Missions themselves tend to be repetitive but provide a rich backdrop for player-driven narratives and memorable, tense moments that define the game's appeal.

    • “Barotrauma is not just a game—it’s an experience, a psychological test, a storytelling machine, and a chaotic masterpiece all rolled into one.”
    • “Every mission feels like a horror movie where you are the characters.”
    • “What makes barotrauma peak fiction isn’t a traditional storyline—it’s the stories you create. And that’s real storytelling.”
    • “The story is weak and barely there until right at the end, and the factions are decent, but ultimately pretty ignorable.”
    • “The campaign is annoying in some missions where we had to restart many many times and there's like 5 hammerheads alongside 2 matriarchs just right there at spawn but it's worth the blood sweat and tears we put into beating the campaign, no spoilers for the final mission other than it's hell and we went through the 7 stages of grief, but after beating it I've opened my third eye and the true genius of this game was revealed, the struggle is worth it, so, I strongly recommend this game, beat the game on ironman mode on abyssal difficulty it's a life changing experience.”
    • “The game doesn't respect your time, and every mission feels like a gamble where the odds are stacked against you for no good reason.”
  • humor
    1,095 mentions Positive Neutral Negative

    The humor in Barotrauma is widely praised for its dark, chaotic, and often slapstick comedy, especially in multiplayer settings where unexpected disasters, player mishaps, and ragdoll physics create endless hilarious moments. The tension between serious survival gameplay and absurd antics—such as sabotaging the submarine or goofy character interactions—makes for a unique blend of horror and humor that players find highly entertaining. Overall, the game's humor thrives through emergent situations, player dynamics, and a supportive, lively community that turns failure and chaos into memorable laughter.

    • “The mix of teamwork, horror, and dark humor keeps things fresh, and no two runs feel the same.”
    • “As when things go wrong "and they will", it’s either stressful, hilarious, or both.”
    • “Barotrauma is hands-down one of the most chaotic and hilarious co-op experiences you can have, as long as your crew doesn’t implode faster than the sub.”
    • “Now I know how to make unfunny mods and prank random players in public servers with my fart grenade.”
    • “But not funny enough sometimes.”
    • “Not funny.”
  • atmosphere
    709 mentions Positive Neutral Negative

    Barotrauma excels in creating a uniquely tense, immersive, and claustrophobic atmosphere, effectively conveying the dread of deep-sea survival on an alien moon through its sound design, visual style, and team-based gameplay. Despite its 2D graphics, the game masterfully combines eerie ambience, dark underwater horror vibes, and dynamic, unpredictable scenarios to keep players deeply engaged. Many reviewers highlight that playing with friends enhances the atmosphere, making the experience both thrilling and memorable, while the game's detailed mechanics and modding support further enrich this compelling environment.

    • “The atmosphere is tense and immersive, and the game really shines when things start going wrong (which they always do).”
    • “It has an incredible atmosphere and world design that really gets you hooked and immersed.”
    • “Barotrauma has an incredible atmosphere; the unpredictable disasters too—everything works together.”
    • “But atmosphere alone can’t save a game that is this exhausting to play.”
    • “While it does allow you to experience the mechanics and atmosphere of the game (arguably much better than multiplayer) it is ultimately really tedious managing everything yourself in a game meant for multiplayer.”
    • “Barotrauma has a well crafted atmosphere, mechanics that seem very deep at first glance and the game is fun for some time in co-op, but in the end it feels more like a chore than an actual game.”
  • graphics
    574 mentions Positive Neutral Negative

    Barotrauma features a unique, dark, and gritty 2D art style that many find atmospheric and fitting for its underwater, sci-fi horror theme. While the graphics are simple and sometimes described as "wonky" or outdated, they effectively contribute to the game's immersive ambiance and are complemented by detailed animations, lighting effects, and strong sound design. Although not graphically intensive or high-fidelity, customization through mods and the game's distinctive aesthetic make its visuals stand out, especially within its genre, though it may not appeal to those expecting modern 3D graphics.

    • “The graphics in Barotrauma are fantastic, with a detailed and atmospheric art style that perfectly captures the game's underwater setting.”
    • “The artstyle is perfect for this type of game, it's shady and dark yet not too edgy, it's rough and beautiful and it's easy to tell that was the intended design choice; the developers really delivered.”
    • “The game's stunning visuals and attention to detail bring the desolate yet captivating landscape of Europa to life, while the dynamic AI crew members add authenticity and unpredictability.”
    • “The graphics are horrible.”
    • “Graphics: 2/10 - the art is incredibly ugly.”
    • “Terrible graphics, I am not a fan of the ragdoll style.”
  • music
    272 mentions Positive Neutral Negative

    The music in this game is widely praised for its atmospheric, eerie, and immersive qualities that significantly enhance the horror and tension of underwater exploration. Its soundtrack ranges from ambient, subdued tracks to intense and dramatic pieces that adapt well to gameplay, creating a unique and memorable audio experience. While some find it repetitive after long sessions, the overall consensus highlights the music as a major strength that complements the game's setting and vibe perfectly.

    • “The soundtrack is superb, in my opinion it really encapsulates the world and its feel.”
    • “The music is incredible, the design is lovely, the atmosphere is damp, pressurized and bleak.”
    • “All of this combines with the fantastic soundtrack to create a wonderful ambient soundscape.”
    • “The soundtrack kinda just plays random tracks and sometimes it doesn't fit what's going on at all.”
    • “Also always while I'm playing there's just this one song playing over and over and it doesn't really fit the atmosphere and it just makes me keep the music volume on 5% at all times.”
    • “Graphics are fine, music could be better, this game is focused so much on gameplay out the wazoo and that's why I love this game and any future updates with it, along with a strong modding community.”
  • grinding
    219 mentions Positive Neutral Negative

    Grinding in this game is widely described as tedious, repetitive, and time-consuming, especially in single-player mode where micromanagement and resource gathering can become overwhelming. While some players find the grind frustrating and dull, others appreciate the depth it adds and enjoy the challenge when playing cooperatively with friends. Overall, grinding is a significant aspect that may deter casual players but appeals to those who like intricate, slow-paced gameplay.

    • “It's janky enough that it becomes funny but not tedious or weird; it has a serious and scary tone but then you have underwater clown cults.”
    • “A bit grindy sometimes.”
    • “You'll need a second life for grinding.”
    • “Grinding missions for cash can get very repetitive so be warned of that.”
    • “The undertow development team has truly made a blunder by the rework of this system, and effectively made grinding in their game focused on grinding in order to finish a campaign practically physically painful.”
    • “Skill gain in general was very silly with a lot of things coming down to runescape style grinding for increasing levels.”
  • stability
    218 mentions Positive Neutral Negative

    Barotrauma is notably buggy and unstable, with frequent glitches, crashes, and AI issues affecting both singleplayer and multiplayer experiences. While many find the bugs frustrating or game-breaking, others see them as part of the game's charm, especially when playing cooperatively with friends and using mods. The developers continue to improve stability, but performance and connectivity problems remain significant concerns for some players.

    • “The game seems to be relatively bug free and offers a bit of a learning curve.”
    • “Runs great on most systems, though it does require a stable connection when playing with friends.”
    • “Sure, it booted up fine, with no glitches or installation errors.”
    • “Constantly some annoying stuff is happening: getting stuck at doors, wonky physics causing character glitches, unintentional item pickups due to buggy UI, getting infected on contact with husks, submarine being attacked during outside cave clearing, disappearing lootable dead bodies, and NPC crewmembers suffocating in their scuba suits due to AI not managing oxygen properly, leading to mission failures.”
    • “Stupidly badly written spaghetti-code game requiring belief in god, kraken, and modern processor architecture to play mods; even simple mods can cause memory leaks, excessive entity counts, freezing, and hardware crashes, resulting in complete game or PC failure within minutes to months.”
    • “Just hope the next update doesn't come mid-campaign; my friend and I have had to restart our campaign about 6 times due to game-breaking glitches ranging from loading issues on older versions to disconnections causing character deaths and softlocks where we couldn't leave the submarine due to lack of extra dive suits and lost weapons.”
  • optimization
    202 mentions Positive Neutral Negative

    Barotrauma suffers from significant optimization issues, especially in multiplayer, late-game scenarios, and when using mods or large submarines, often causing severe lag, FPS drops, and server instability. While some community "performance fix" mods help alleviate these problems, they are seen as band-aids rather than true solutions. Despite ongoing updates improving performance somewhat, many reviewers note that the game remains poorly optimized for its scope, with single-core CPU reliance and unresolved technical issues detracting from the experience.

    • “The gameplay is really solid, performance is great, and there's very few bugs (at least that I've seen), and there's also native Linux builds which is pretty cool, no having to run it through Proton.”
    • “Barotrauma is optimized to run on a wide range of systems, from older PCs to modern gaming rigs.”
    • “Rocky start but over the years they fixed every major issue I can think of, improved performance to an insane level and they continue to put in a lot of effort, thought and work into this game.”
    • “The game is very poorly optimized, the online experience is very unstable, even if you build a dedicated server; there will still be packet loss and stuttering, leading to a rather low game experience for veteran players.”
    • “The only downside to this game is that it is horribly optimized, runs on one CPU core, and tends to stutter itself into oblivion mostly in the 3rd and 4th biome, making a modded "lag fix" almost mandatory.”
    • “Newly introduced performance issues since the Rising Tide update have made the game quite literally unplayable for me and hundreds of other players.”
  • replayability
    197 mentions Positive Neutral Negative

    Barotrauma offers exceptional replayability, driven by its procedural generation, diverse roles, varied missions, and extensive modding community. The game's dynamic gameplay, cooperative multiplayer, and customizable submarines ensure that no two sessions are alike, providing nearly infinite replay value. Frequent updates and active player involvement further enhance its longevity and depth.

    • “One of the best games I have ever played, the replayability of this game is insane; no two runs will be the same. Plus, there is an active modding community and players constantly, so you can always find someone to play with.”
    • “With its rich modding support and growing community, Barotrauma provides endless replayability, making it a must-play for fans of cooperative survival games.”
    • “The replay value is also something to commend; vanilla or modded, there's always something new to find that you didn't experience last time you played.”
    • “I just feel like it doesn't really have any replay value.”
    • “The game doesn't provide the amount of content or replayability to justify it.”
    • “I cannot recommend this game to someone looking for a single-player experience, as you will lose most of the replay value for singleplayer within four hours at most.”
  • emotional
    67 mentions Positive Neutral Negative

    Players overwhelmingly describe the game as an emotional rollercoaster, eliciting feelings ranging from wholesome camaraderie and deep attachment to crew members, to intense fear, trauma, and heart-wrenching moments. The game’s immersive atmosphere and unpredictable scenarios create strong emotional investment, often leading to laughter, tears, and lasting memories. Despite some player toxicity, many praise the genuine emotional impact and unique bonding experiences the game fosters.

    • “Give it a shot, and thanks devs. It's been a while since a game made me feel this way.”
    • “Had a really amazing dream crew in campaign mode and got emotionally invested in my crew members.”
  • monetization
    20 mentions Positive Neutral Negative

    Barotrauma's monetization is praised for having no microtransactions, offering a balanced and fun experience without additional costs. Reviewers appreciate its polished gameplay and value compared to pricier AAA games with DLC, though some note slow development on features like the karma system. Overall, the game is seen as a well-crafted, microtransaction-free treasure deserving more advertising.

    • “Every time I see this game I shed a tear. Barotrauma has no microtransactions, isn't a severely broken game, is properly balanced, and actually fun to play. It is the closest to perfect a game can get.”
    • “I would much rather pay $30 for a polished game with zero microtransactions than $60 for a broken AAA game with limited content and DLC on release.”
    • “That being said, I would much rather pay $30 for a polished game with zero microtransactions than a $60 AAA game that is broken with three maps and DLC on release.”
    • “Coding the karma system should have done faster and not be a cash grab.”
    • “Every time I see this game I shed a tear; Barotrauma has no microtransactions, isn't severely broken, is properly balanced, and actually fun to play. It is the closest to perfect a game can get.”
  • character development
    12 mentions Positive Neutral Negative

While some find the character designs lacking or prefer mods, the overall roleplaying experience and story progression are engaging and immersive.

    • “It's the player roleplaying/character development that pushes it even further though hahaha... love the interactions, the mood, atmosphere, and setting.”
    • “Excellent game that keeps getting better and better with regular updates from the devs. Recently they overhauled character development and I can't wait to hop back in and check it out!”
    • “It is a unique simulation unto itself with a smorgasbord of features including character development, crafting, factions, and unique storyline that develops as you progress through the single player campaign.”
    • “Incredibly offputting character design”
    • “Character designs leave something to be desired, but enemy designs are quite fantastic and some of them will send a chill through your blood.”
    • “Character design and story rated only 6 out of 10.”
