    The gameplay of this co-op survival horror game is praised for its unique sanity and hallucination mechanics, intense atmosphere, and engaging cooperative experience, though it is often described as clunky, repetitive, and lacking polish. Combat is widely criticized for being frustrating due to sluggish controls, lack of defensive options like blocking or dodging, and poor enemy balance. While the core loop and concept show strong potential, many reviewers highlight the need for better tutorials, optimization, and more diverse, meaningful gameplay progression to fully realize the game's promise.

    • “Gameplay videos reveal enough, but the highlight of this game is the hallucination system that constantly has people on guard questioning if what they're seeing is real.”
    • “The gameplay loop is very engaging but it is missing a little bit of depth, though I cannot really tell what is missing.”
    • “Gameplay loop is deeply engaging and, honestly, freaking terrifying at times.”
    • “Repetitive game, with lazy developers who did the bare minimum, and mechanics that straight up suck.”
    • “The combat system is genuinely one of the worst I have ever seen in any game and the gameplay relies heavily on combat.”
    • “Clunky controls, poor performance, and boring gameplay mechanics.”
  • story

    611 mentions Positive Neutral Negative
    10% positive mentions, 86% neutral mentions, 4% negative mentions

    The story is generally seen as minimal and delivered mainly through collectible logbooks and background lore, with few cinematic or immersive narrative moments. While some appreciate the Lovecraftian setting and atmospheric worldbuilding, many find the missions repetitive, lacking clear progression or meaningful character development, and the overall storyline underwhelming or confusing. Players often critique the absence of impactful story integration within gameplay, limited mission variety, and a lack of rewarding narrative payoff, resulting in diminished engagement beyond the initial hours.

    • “Love this game, great horror, great story, can't wait for more.”
    • “The story, conveyed through the Tempestad characters and logbooks, also comes across very well thanks to the excellent voice actors.”
    • “The game's lore is really interesting and delivered to you in a fashion that I myself enjoy (at the end of a mission if you collected a logbook you get to learn about the next mission). The writing and voice acting make it really interesting, in my opinion.”
    • “The missions make no sense and lack a clear storyline.”
    • “You will spend hours completing a quest just to get a lame ending.”
    • “The final mission and the ending don’t help either, making the whole conclusion feel anticlimactic.”
  • optimization

    455 mentions Positive Neutral Negative
    14% positive mentions, 66% neutral mentions, 20% negative mentions

    The game's optimization is widely criticized, with many users reporting poor performance, frequent lag, stuttering, crashes, and high system demands even on powerful PCs. While some players experience smooth gameplay after tweaking settings or on high-end rigs, the consensus is that optimization is inconsistent and needs significant improvement, especially on consoles and lower-spec machines. Developers appear responsive to feedback, with patches partly improving performance, but overall the game currently struggles with Unreal Engine 5-related inefficiencies and requires further optimization for a stable, enjoyable experience.

    • “Extremely unique and fun game, decent performance and great graphics on high with Geforce 3000 series GPU.”
    • “The last update improved the performances a lot.”
    • “Performance and optimization are also surprisingly solid for an Unreal Engine title.”
    • “This is one of the worst optimized games I've played lately, with the culprit being a classic case of misused modern Unreal Engine features.”
    • “This is the worst optimized game I've ever seen; it's absolutely unplayable.”
    • “Runs horribly even on low-medium settings (constant stuttering and low fps even when not in dense forest areas), combat and movement feel slow.”
  • atmosphere

    365 mentions Positive Neutral Negative
    64% positive mentions, 35% neutral mentions, 1% negative mentions

    The game excels in creating a dense, oppressive, and uniquely Lovecraftian atmosphere, praised for its eerie sound design, unsettling visuals, and immersive psychological horror elements like sanity mechanics and hallucinations. Many reviewers highlight the strong co-op dynamic that enhances the tension and dread, making every expedition feel intense and unpredictable. Despite some technical flaws and gameplay roughness, the atmosphere is consistently cited as the standout feature, delivering a deeply immersive and chilling experience unmatched by many in the horror-survival genre.

    • “The atmosphere is so thick you could cut it with a knife and the team really outdid themselves on the sanity mechanics!”
    • “The positives: let me start out by saying that I love the concept, it feels so unique and refreshing for a co-op horror survival to actually be downright terrifying through atmosphere alone rather than relying on jumpscares, with audio cues and a daunting feeling of dread from the visuals, it genuinely feels like you're being watched.”
    • “Once you’re actually in the game, the atmosphere is thick, oppressive, and beautifully unsettling.”
    • “All in all, the atmosphere that made the early game shine takes a huge backseat once the late game kicks in; at that point, atmosphere is really the only thing I can still say is good about the experience.”
    • “There is a lot to be wished for, honestly, and the full potential of the game's sanity mechanic, exploration, and atmosphere isn't fully realized, in my opinion.”
    • “Combat is janky and the immersion just isn't there despite an honest attempt from the developers to create atmosphere.”
  • graphics

    251 mentions Positive Neutral Negative
    51% positive mentions, 46% neutral mentions, 3% negative mentions

    The game features stunning and immersive graphics with detailed environments, atmospheric lighting, and effective visual effects that greatly enhance its horror and exploration elements. However, many users report significant performance and optimization issues, including low frame rates and graphic glitches, even on mid-to-high-end hardware, which detract from the overall experience. While the visuals are praised as a core strength, inconsistent graphical settings and bugs suggest a need for further polishing.

    • “The graphics (flora, fauna, and especially weather effects like fog, etc.) are outstanding, as is the sound design.”
    • “The graphics are amazing walking through the jungle forest is great.”
    • “The graphics and level of detail are fantastic — you’ll genuinely get lost staring at the environments.”
    • “Runs pretty bad and looks fine graphically aside from the frequently visible Blender default cubes and the low-quality textures looking like chewed bubblegum.”
    • “There are huge issues with screen resolution scaling, and the FPS is surprisingly low even on the lowest settings with an 8 GB graphics card.”
    • “However, I cannot recommend the game without the caveat that you will end up with flashing purple/red textures/shadows constantly. I believe the issue lies in the lighting rendering, as changing the appropriate setting will fix it for a few seconds before it reverts to strobing again. This began in the prologue and continued for the full 25 minutes of gameplay.”
  • stability

    121 mentions Positive Neutral Negative
    8% positive mentions, 1% neutral mentions, 91% negative mentions

    The game is widely reported as buggy and unstable, with frequent crashes, performance issues, and glitches affecting gameplay, AI, UI, and multiplayer functionality. While some players experience minimal problems and find it fun, many highlight the need for optimization, bug fixes, and polish before it can be considered a stable and fully enjoyable experience.

    • “Definitely runs great at 2560x1600 at a good 90-140 fps on ultra settings.”
    • “I have not experienced any performance issues, game looks good and runs great for me.”
    • “Had no problems running and no glitches, can't wait to play more.”
    • “On top of the fun features of just the game itself, it's loaded with bugs: game freezes when opening the upgrades menu, issues with the logbook, servers disconnecting, and more.”
    • “However, this was purchased with the intention of primarily playing in multiplayer mode, which since the last patch, has become completely unusable even after extensive troubleshooting.”
    • “Buggy monsters: enemies often perform random actions or have broken hitboxes, making it impossible to reliably venture out alone to gather materials.”
  • humor

    57 mentions Positive Neutral Negative
    100% positive mentions, 0% neutral mentions, 0% negative mentions

    The game's humor shines brightest when played co-op with friends, blending intense, chaotic scares with hilarious hallucinations and unpredictable moments that turn panic into laughter. The insanity mechanics and Lovecraft-inspired atmosphere create a unique mix of creepy and funny experiences, often leading to memorable, lighthearted team interactions despite some bugs. Overall, humor is a key highlight that enhances the tense gameplay, making it a fun and entertaining social experience.

    • “Some of the funniest and most memorable moments came from the game making us question each other, leading to hilarious situations, panic, and a lot of laughter.”
    • “The insanity mechanics are easily the highlight, creating some genuinely memorable and hilarious moments.”
    • “With friends, it becomes something special — a strange, moody, cthulhu‑flavored expedition that’s as funny as it is unsettling.”
  • music

    24 mentions Positive Neutral Negative
    33% positive mentions, 54% neutral mentions, 13% negative mentions

    The music and soundtrack receive high praise for effectively enhancing the atmosphere, tension, and Lovecraftian vibe, with many users calling it a standout aspect of the game. Some players appreciate the inclusion of a bard and collectible songs, though there are occasional technical issues with accessing music options. A few users noted the lack of ambient music at times, which can make the world feel lifeless or slow, but overall the audio design significantly contributes to the game's eerie and immersive experience.

    • “The soundtrack and sound design deserve a particular mention.”
    • “The environments, music, overall vibe, and constant sense of dread absolutely nail the feeling of a Call of Cthulhu adventure.”
    • “Audio: the soundtrack and spatial design do a fantastic job of building paranoia and matching the Lovecraftian setting.”
    • “Please add in some music.”
    • “The silence can be eerie, but playing for so long with no droning music or tension-building tracks is very... meh.”
    • “The lack of ambient music makes the world feel lifeless, and almost everything your character does feels painfully slow.”
  • replayability

    20 mentions Positive Neutral Negative
    20% positive mentions, 65% neutral mentions, 15% negative mentions

    Replayability is a mixed but generally promising aspect, with praise for varied encounters, atmosphere, and cooperative tension that keeps runs feeling fresh. However, many users note the current lack of post-campaign content, progression systems, and sufficient variation after initial playtime, suggesting the game still feels like early access and needs more content and features to sustain long-term player engagement. Developers are encouraged to focus on enhancing replay value through progression, additional activities, and expanded multiplayer options.

    • “Lots of replayability and it even works on Steam Deck!”
    • “This game is perfect in my opinion; even with the same map, there's some variation that provides proper replayability as the hallucinations mostly aren't set up as a standard encounter and tend to vary a lot.”
    • “Amazing atmosphere and level-to-level replayability.”
    • “It will die if the devs don’t add replay value or a progression system quickly.”
    • “Game starts off fun with friends but after 2-3 hours of playtime, nothing changes and there is not much replay value.”
    • “What had replayability for me personally no longer does.”
  • grinding

    19 mentions Positive Neutral Negative
    0% positive mentions, 0% neutral mentions, 100% negative mentions

    Grinding in the game is often described as tedious and frustrating due to limited permanent upgrades, small inventory space, and repetitive farming for tokens and XP. While the gameplay provides challenging combat that appeals to hardcore players and cooperative sessions can be enjoyable, the overall feedback loop and progression feel unrewarding and grind-heavy, leading to a less engaging experience for some.

    • “It's very rare to get permanent upgrades and it's a little grindy in that sense.”
    • “The feedback loop to the player is dismal - and it makes me feel like this game is only suited to hardcore Dark Souls players who enjoy grinding over and over to get timings perfect - literally the reason I don't care to play souls.”
    • “This game is good, if you're put off by people complaining of difficulty then find another game, no harm, no foul but, I'll keep grinding the Amazon with my friends for eldritch artifacts and blowing the noggins off of zombies with black powder, thanks.”
  • character development

    6 mentions Positive Neutral Negative
    50% positive mentions, 0% neutral mentions, 50% negative mentions

    Character development in the game is currently minimal or underdeveloped, with users appreciating the strong character design and voice acting but noting a lack of meaningful progression or growth. Many feel the game would benefit from enhanced character and weapon development systems to fully realize its potential.

    • “The graphics look good, the character designs look interesting, and the dark/gloomy feel of the game had me hooked.”
    • “Character design and voice acting are solid.”
    • “Good game, ambiance is good, character design is good.”
    • “Weapon and character development needs to be added or optimized.”
    • “Has a ton of potential if the missions built toward something, character development or something.”
    • “This game has great visuals and character designs, though the controls are lacking, as well as the 'difficulty'.”
