    The story of "The Callisto Protocol" has received mixed reviews, with many players finding it predictable and derivative, often drawing comparisons to "Dead Space." While some appreciate its engaging atmosphere and character development, others criticize it for being shallow and lacking depth, particularly in the latter half where it feels rushed and incomplete. The game's narrative is described as a straightforward sci-fi horror tale, with a cliffhanger ending that leaves players wanting more, often leading to disappointment over the necessity of purchasing DLC to fully resolve the story. Overall, while the visuals and sound design are praised, the story's execution has left many feeling underwhelmed.

    • “In fact, the story is one of the reasons that made me play straight for 12 hours because I wanted to see how it ends!”
    • “The story is engaging, characters are decent, and the combat, which seems to be criticized, is actually weighty feeling and fun.”
    • “The story is well told and it is action packed, which keeps you from getting bored.”
    • “The story isn't anything special, and once you've completed 20% of the game, the rest of it is exactly the same.”
    • “The story isn't satisfying and the set-pieces are underwhelming; the characters are not particularly captivating either.”
    • “The story is forgettable, and I cannot recommend paying sixty dollars for this game.”
  • optimization5,898 mentions

    The optimization of "The Callisto Protocol" has been a significant point of contention among players, particularly at launch, where many experienced severe stuttering and frame rate drops, rendering the game nearly unplayable. While subsequent patches have addressed many of these issues, allowing for smoother gameplay on higher-end systems, some players still report occasional stuttering and performance inconsistencies, especially with ray tracing enabled. Overall, while the game has improved since its initial release, it still requires further optimization to meet the expectations of players with varying hardware setups.

    • “Despite the performance issues, I thoroughly enjoyed the ambiance, atmosphere, level design and sound design this game offered.”
    • “The performance issues have been improved a little after some patches (as of 3 days after release), but it's still not good enough.”
    • “The game looks amazing and I'd love to see it better optimized so I can crank some of the ray tracing settings without killing my fps.”
    • “The performance is atrocious and unstable, even after the patches.”
    • “The game is a stuttering mess and not in a fit state for release.”
    • “The stuttering and frame drops are so persistent and noticeable that they ruin combat and shatter the immersion.”
  • gameplay4,245 mentions

    The gameplay of "The Callisto Protocol" has received mixed reviews, with many players praising its stunning visuals and atmospheric design while criticizing its combat mechanics. The melee-focused gameplay, which relies heavily on a simplistic dodge mechanic, often feels repetitive and clunky, especially in encounters with multiple enemies, leading to frustration rather than the intended tension. While some players appreciate the unique approach to combat and the integration of horror elements, others find the overall experience lacking in depth and innovation compared to its predecessor, "Dead Space."

    • “The gameplay is fun and the combat is satisfying.”
    • “The melee combat mechanics, especially the dodge mechanic, seem pretty novel.”
    • “The gameplay is a perfect balance of intense combat with gruesome enemies who absolutely want you dead and finding your way through macabre levels that seem to pull you deeper into them.”
    • “Stunning visuals, perfect directing, cinematography, sound design but boring and shallow gameplay, broken close combat and meaningless story.”
    • “The way the mechanics are introduced and painfully explained to players is a pretty clear indication that playtesting showed that 'hey folks aren't getting this and we can't design a better solution, just explain it with a popup'.”
    • “The gameplay is extremely repetitive and not that fun to begin with.”
  • graphics4,011 mentions

    The graphics of "The Callisto Protocol" have received widespread acclaim for their stunning visuals and attention to detail, often described as some of the best seen in recent gaming. Players have praised the game's atmospheric design, character models, and the realistic portrayal of gore, which significantly enhance the horror experience. However, many reviews also highlight performance issues, including stuttering and frame rate drops, particularly on lower-end systems, suggesting that while the graphics are impressive, they come at the cost of optimization and gameplay fluidity.

    • “The graphics are stunning, it was refreshing having new survival horror elements implemented to a game, overall, not a bad experience at all and highly recommend to anyone who's been looking to scratch that survival horror itch.”
    • “The graphics are absolutely stunning, the lags are there... it's not an amazingly optimized game at the moment but once again, this can be fixed down the road, it does not take away from the fact that the core gameplay is phenomenal.”
    • “The graphics are incredible, the sound design is amazing, the music is phenomenal, but ultimately the game falls short in every category of what made the original dead space so good.”
    • “The graphics are the only saving grace of this game.”
    • “It feels like the developers sacrificed gameplay depth to focus on graphics.”
    • “The graphics are a feast for the eyes, rendering a cosmos that's both eerie and enchanting.”
  • atmosphere1,851 mentions

    The atmosphere of "The Callisto Protocol" is widely praised for its stunning graphics, immersive sound design, and intense, oppressive environments that evoke a sense of dread reminiscent of the "Dead Space" series. Many players appreciate the game's ability to create a haunting ambiance, filled with tension and anxiety, although some note that it relies heavily on jump scares rather than building sustained horror. Overall, while the atmosphere is a standout feature, it is often contrasted with criticisms of the gameplay mechanics and story depth.

    • “The atmosphere is breathtakingly gorgeous.”
    • “The atmosphere and visuals are gorgeous, and likely some of the best of this current generation.”
    • “The atmosphere is creepy and uninviting (perfect); pairing that with a story is intriguing and mysterious and I couldn’t help but keep coming back to explore more.”
    • “Boring, not scary, no horror atmosphere.”
    • “The atmosphere just never quite gets there.”
    • “The atmosphere is very eerie, and the score slowly gets more powerful as enemies close in.”
  • stability484 mentions

    The stability of the game has received mixed reviews, with many players reporting significant issues such as frequent freezes, crashes, and glitches, particularly during loading screens and cutscenes. While some users noted improvements after patches, others still experienced persistent stuttering and performance problems, even on high-end systems. Overall, the game appears to have launched in a buggy state, with ongoing optimization needed to enhance the gameplay experience.

    • “First thing, let's talk performance: the graphical stutter issues that plagued the game during launch are no longer present. The game now compiles all shaders when you first launch it, and it runs butterly smooth throughout. I managed to get 100fps average on my RTX 3060 Ti at 1080p with everything maxed out (no ray tracing).”
    • “After a few patches, the game runs great on my system. I have a laptop with a 3060, and the game runs great.”
    • “The game runs great now with zero to very limited stuttering. I loved the game, never had a problem playing it, no glitches, stutters, or anything.”
    • “Since the second time I booted up the game, 'continue' just straight up freezes a few seconds into the loading screen and I can't even play.”
    • “If I load the game or click continue it freezes the game and after 40 minutes of trying all the fixes I could find in the support and discussion board, nothing works. The only thing that would work was to start a new game, but the new game save does the same thing, so that means every time I want to play it is to start a new game and lose all my progress every time.”
    • “This game is a buggy mess, even months after release.”
  • music342 mentions

    The music in the game has received mixed reviews, with many praising its atmospheric qualities that enhance the horror experience, while others find it forgettable or overly repetitive. Some players noted that the soundtrack effectively builds tension during encounters, but can also detract from immersion due to its predictability and reliance on jump scares. Overall, while the sound design and music contribute significantly to the game's ambiance, opinions vary on its memorability and execution.

    • “The soundtrack, while not particularly memorable, effectively complements the atmosphere, ramping up the tension during encounters and offering moments of reprieve during exploration.”
    • “The music and sound design is absolutely flawless, and the graphics are beyond any doubt absolutely insane, 10/10 and easily the best graphics I have seen in my life until now.”
    • “Every single scare, every single jump, every single lonely hallway, every single eerie musical note was placed in such a specific manner where you honestly feel like you are playing a horror movie, I get a lot of John Carpenter vibes here with the incredible amount of tension and suspense.”
    • “Audio triggers are so broken that you can be in an empty room with the music swelling to some peak tense moment, only for nothing to happen, like the game forgot to have enemies or some jumpscare.”
    • “The soundtrack sounds like something that was created by an AI with the prompt 'make the most generic sci-fi sounds in history'.”
    • “The soundtrack is useless and actually hurts the game's ability to generate scares by creating a loud atmosphere which hurts its own jumpscares (turn the soundtrack off if you want to get anything out of the game's horror element).”
  • grinding256 mentions

    The grinding aspect of the game has been widely criticized for its tedious and repetitive gameplay, particularly in combat and traversal mechanics. Players frequently mention the lack of enemy variety, cumbersome melee combat, and frustrating checkpoint systems that force them to redo lengthy and monotonous tasks after dying. Overall, many reviewers find the experience to be a slog, detracting from the game's potential enjoyment and horror elements.

    • “Weapon/general utility upgrade system is simple, but not tedious.”
    • “A bit grindy sometimes.”
    • “You'll need a second life for grinding.”
    • “The combat is both fun and tedious.”
    • “The game stopped being scary and got tedious very early on.”
    • “The 'combat' and moment-to-moment gameplay is the most egregious fault of this game, possibly the most bafflingly tedious and boring combat system ever put to a high-budget title.”
  • replayability205 mentions

    The replayability of the game is largely criticized, with many reviewers noting its linearity and lack of meaningful content to encourage multiple playthroughs. While some players appreciate the addition of new game+ modes and varying difficulty levels, the overall sentiment is that the game offers limited replay value, often described as "zero" or "minimal." Many suggest waiting for future updates or sales before purchasing, as the current state does not justify its price given the short playtime and lack of engaging replay incentives.

    • “I would recommend it to anyone willing to play it; there's plenty of replayability with the new modes they've added and different difficulties to keep you on your toes with New Game+.”
    • “It has satisfying core gameplay, and discovering new details by collecting all the audio logs makes replayability enjoyable, especially if you're fond of challenging yourself with the increasing difficulty modes they've added.”
    • “Overall, a great game and it definitely has replay value.”
    • “The game's only ~10 hours long and doesn't offer any replay value.”
    • “There is little to no replay value at the moment, which might change with the scheduled updates in the future.”
    • “The replayability is non-existent and the lack of a new game+ doesn't help its case.”
  • humor115 mentions

    The humor in the game is often described as unintentional, stemming from its awkward mechanics, predictable jump scares, and absurd design choices that lead to comical situations. Players find the combination of brutal death animations, clumsy enemy AI, and the game's overall campiness to be amusing, creating a blend of horror and humor that feels more funny than frightening. Many reviews highlight the game's glitches and design flaws as sources of laughter, making the experience entertaining despite its shortcomings.

    • “Even more funny is they try to make the vent crawling seem scary with all the scary noises as you crawl, but you literally can't do anything while in the vents so there's nothing scary about it at all.”
    • “The funny thing is if there are more than 1 enemy, they will wait for you to finish your fighting sequence with the other enemy to charge at you which is not interesting, not intense, not scary.”
    • “The combat is kind of difficult in the beginning but once you understand it's so so funny and intense.”
  • emotional93 mentions

    The emotional aspect of the game has received mixed reviews, with some players expressing deep emotional responses, including tears and feelings of sadness, while others criticized the story for being predictable and lacking character development, which diminished their emotional investment. Many noted that while there were moments of tension and potential emotional depth, these were often undermined by poor writing and gameplay mechanics, leading to a frustrating experience rather than a fulfilling emotional journey. Overall, the game seems to struggle with balancing its emotional narrative with engaging gameplay, leaving players divided on its impact.

    • “I cried, I suffered, I had a bruv.”
    • “I've been impressed with the emotional beats of the story, both from different character interactions and just general tension.”
    • “It's an absolute emotional roller coaster, from anger, fear, through frustration and desperation - to shiny moments of hope.”
    • “Poor, predictable, and boring story.”
    • “Boring story, didn't give a damn about any of the characters.”
    • “Just an absolute mess, with a mediocre and boring story.”
  • character development91 mentions

    Character development in the game has received mixed reviews, with many players noting a lack of depth and pacing issues that hinder emotional engagement. While some characters are appreciated for their design and potential, the overall execution often feels rushed or shallow, leaving players wanting more backstory and meaningful interactions. Despite impressive visuals and a unique atmosphere, the narrative fails to fully capitalize on character arcs, resulting in a disconnect between players and the characters' motivations.

    • “I loved the characters, Elias, Danny, Max, Jacob, Warden, Mauhler, and Faris, which were all very interesting in their own right and everyone had a fair bit of character development.”
    • “The story and plot keep you interested the entire time; there's just the right amount of character development to make you feel connected to them and look forward to finding out what happens to them next.”
    • “What truly sets 'The Callisto Protocol' apart is its narrative and character development.”
    • “The issue is character development, or the lack thereof.”
    • “Everything needed for character development is absent, including dialogue and backstory.”
    • “There is no character development and/or memorable characters that warrants even a sequel.”
  • monetization51 mentions

    The monetization strategy of the game has been widely criticized, with many reviewers labeling it a "cash grab" due to excessive advertisements, exploitative microtransactions, and the sale of cut content as DLC. Players express frustration over the game's short length and lack of meaningful upgrades, feeling that the developers prioritized profit over quality and player experience. Overall, the monetization approach has significantly detracted from the game's reception, leading to disappointment among fans.

    • “Lastly, the displayed monetization, in the form of cut content being sold separately, serves as an example of why video games keep devolving.”
    • “Not sure what they can do about the gameplay though, especially after hearing about the monetization (death animations as DLC... really? for a $60 game...).”
    • “The devs could have made a great game, but instead, the publisher decided to milk things as much as they could and... just read other reviews about monetization.”
    • “Terrible cash grab project so far.”
    • “The only way to change the suit's appearance (not stats or anything good) is the preorder bonus, a Twitch drop, or microtransactions/the season pass.”
