  • Engaging survival horror co-op gameplay with tense combat, strategic puzzles, and resource management reminiscent of classic Resident Evil games.
  • Generous friend pass allowing up to 4 players to play with just one copy, making it very accessible and excellent value.
  • Appealing pixel art style and atmospheric sound design that enhance immersion and nostalgia for the genre.
  • No save or progression system initially, requiring completing entire runs in one session, which frustrated some players (later patches added saves).
  • Limited content at early access launch, with only one scenario available and a repetitive endless horde final mission lacking a satisfying ending.
  • Some bugs, connectivity issues, and occasional crashes especially in co-op that impact gameplay experience.
  • story

    246 mentions Positive Neutral Negative

    The game's story is engaging but currently limited and incomplete, with missions focused on retrieval and escape amid puzzles and survival challenges. Players appreciate the atmospheric storytelling through environmental cues and lore, but criticize the abrupt and repetitive final mission, which is an endless survival mode lacking a satisfying conclusion. Many anticipate more story content, varied mission types, and improved progression systems in future updates to enhance narrative depth and replayability.

    • “The narrative framework is deliberately understated, allowing the environment to do much of the storytelling.”
    • “As of now, the game is mission-based, approximately 2-3 hours long, with one area consisting of 8 missions taking 10 to 30+ minutes each, featuring clear progression, simple but fun puzzles, and not an overly complicated story so far.”
    • “Players must work together to uncover the mystery and escape, completing missions and solving puzzles along the way, with the story weaving together Indonesian folklore and foreign myths, creating a unique and enjoyable mix.”
    • “The final mission is an endless horde that will keep going until you either die or just quit the game, offering no real ending or resolution.”
    • “Every time you die, you have to restart the whole campaign because the missions get repetitive and there isn’t a huge variety in missions, which gets old fairly quickly.”
    • “The last mission is a survival wave defense with no real conclusion, feeling lackluster especially after the buildup throughout the game.”
  • gameplay

    163 mentions Positive Neutral Negative

    The gameplay is widely praised for its tight, engaging core loop that blends survival horror, puzzle-solving, and cooperative play reminiscent of classic Resident Evil titles. The mechanics, including inventory management, combat, and puzzle design, offer a nostalgic yet fresh experience, especially in co-op, though some note limited content variety and repetition over time. While generally smooth and enjoyable, a few technical issues and the absence of a save feature detract from the overall experience, but ongoing updates and planned expansions promise to enhance the gameplay further.

    • “The gameplay is tight and cohesive, the upgrades are very impactful, enemy variety is decent for how quick the experience is.”
    • “This game reminds me of Resident Evil 1 and 2 feel with an Enter the Gungeon-like gameplay, the mechanics are smooth and the challenges fair. Inventory management isn't too stressful but it still makes you think before you keep an item. There's also a roguelike pathways level select reminiscent of games like Slay the Spire, and a very easy and intuitive upgrade system with coop play. I'd recommend giving it a shot.”
    • “The core gameplay consists of you (and your team, if you have one) entering a map, gathering resources and completing the objective before going to extract.”
    • “At its current state there's not a whole lot of gameplay but it's definitely worth your money as they get more scenarios in.”
    • “I reviewing this game negative just for the simple fact that the game crashes on its own after 3 minutes of gameplay; I played 5 times and 5 times did the same thing: the FPS drops from 60 to 5, and then the game crashes. I hope they fix it because the game is actually very good.”
    • “Controls are weird, and gameplay was just not fun.”
  • graphics

    84 mentions Positive Neutral Negative

    The game features a distinctive retro pixel art style that blends nostalgic 2D sprites with modern 2.5D and low-poly 3D environments, creating a unique, atmospheric aesthetic reminiscent of classic '90s horror games. Reviewers praise its charming visuals, cohesive art direction, and ability to evoke a tense, immersive vibe despite simple graphics. While some note minor limitations in character customization and early access polish, the graphics are widely regarded as a major strength that enhances the gameplay experience.

    • “Visually, the game blends pixel-art character sprites with 3D environments, creating a distinctive aesthetic that feels both nostalgic and modern.”
    • “The art style nailed the original 90's survival horror video game vibes while taking it somewhere new with the 2.5D pixel art.”
    • “It has beautiful pixel visuals, grotesque and impressive monster designs.”
    • “Btw I couldn't visually discern a difference with the game's graphics regardless of the settings I played on, even when restarting the game between changing settings.”
    • “Certain graphics and sounds could use a bit of work, but that's to be expected of an early access.”
    • “Sound design is alright (some like reloading sounds are stock sounds and are awful). There should be more voice options to choose from. The art style is neat, though there could be much more pixel character designs to choose from - as of now there are only 3 body types, 5 head types, and about 8 colors.”
  • atmosphere

    46 mentions Positive Neutral Negative

    The atmosphere in this game is widely praised for its tense, eerie, and nostalgic survival horror vibe, effectively blending pixel art and sound design to create an immersive, spooky experience. The combination of classic horror elements with cooperative and roguelite mechanics enhances engagement, while the varied, atmospheric level design supports replayability and exploration. Overall, the game's mood and artistic direction stand out as key strengths that deeply draw players into its world.

    • “The atmosphere, exploration, and survival gameplay feel like a love letter to that era of survival horror.”
    • “The pixel art mixed with creepy atmosphere works surprisingly well, and it nails that tense, eerie vibe.”
    • “Whisper Mountain Outbreak, developed and published by Toge Productions, is a tense and atmospheric survival horror experience that draws heavily from classic genre traditions while reframing them through a cooperative, roguelite-leaning structure.”
    • “- atmosphere”
    • “Strong atmosphere, mostly needs some refinement and more content.”
    • “Puzzles, coop experience, gameplay, map/level design, atmosphere, almost everything else except-”
  • music

    40 mentions Positive Neutral Negative

    The music and sound design are widely praised for creating a tense, chilling atmosphere that enhances the horror-survival experience, especially during horde sequences. While some note minor issues like music desync and repetitiveness, the soundtrack is considered exciting, immersive, and a standout element that many hope to see released separately. Overall, it effectively complements the game's art style and gameplay, amplifying suspense and player engagement.

    • “The horde music brings out my primal survival instincts like nothing else.”
    • “The tension when entering a room, hearing horde music, or running to the exit vehicle with an unending horde hot on your trail or the timer counting down is exhilarating.”
    • “The warning music builds great tension and gives the game an excellent balance overall.”
    • “Yes - the royalty free music is whack, the monsters can be repetitive, but at its core, this game is a ton of fun with some friends!”
    • “The only other issue I've found is music desync: the horde incoming music is set to play in full as soon as it starts, and doesn't pause when you do.”
    • “The one song that tells me a horde is coming up can be a little draining to hear over and over. So, I'd suggest making new songs to compensate, but the song is helpful in telling me when to get ready.”
  • replayability

    30 mentions Positive Neutral Negative

    Replayability in the game receives mixed feedback; while procedural generation, class variety, and roguelite elements provide some replay value, many players find it limited due to repetitive objectives, lack of content, and short campaign length. Suggestions to enhance replayability include adding more maps, weapons, missions, progression systems, and multiplayer improvements. Overall, the game shows potential but needs further content and variety to sustain long-term engagement.

    • “Each player chooses from six unique classes, each with their own skills and perks that encourage replayability and teamwork.”
    • “Replayability is what keeps me playing because when you start the same map again, your encounters will be different.”
    • “My friends and I beat the game first playthrough and the replayability is great, please keep giving love to this game devs!”
    • “A fun experience, but not much replayability.”
    • “Quite fun for the price but lacks replayability.”
    • “There is not a lot of replay value in a game where you'll be replaying the same missions over and over.”
  • stability

    16 mentions Positive Neutral Negative

    The game suffers from frequent bugs, glitches, and crashes that disrupt progress, including character resets, freezing, and problematic voice chat. While some players report severe stability issues preventing mission completion, others experience fewer problems during extended play. Overall, stability is inconsistent and notably detracts from the gameplay experience.

    • “But we never managed to beat the game, not that it's too hard, but because of bugs/glitches of resetting character's bag size or progress completely within the same play session.”
    • “I can barely get past the first room before the game freezes as though it hit a lag spike that you never recover from.”
    • “Constantly freezes and crashes.”
  • optimization

    9 mentions Positive Neutral Negative

    The game features impressive pixel art and generally smooth gameplay, but optimization issues such as stuttering during asset loading and traversal negatively impact the experience, even on high-end rigs. Server performance and reconnecting problems also affect multiplayer, though some users report smooth multiplayer sessions without crashes. Overall, optimization remains a key area needing improvement.

    • “Weapons, skills, gameplay, and performance are really nice for such a game; so far, I would rate it 8/10.”
    • “Also, no performance issues or crashes neither for my friend nor me.”
    • “Multiplayer runs smoothly and is super easy to set up.”
    • “The real issue again is the replay value and just general optimization of the servers and reconnecting / multiplayer.”
    • “Why is this game stuttering so badly when my rig is well above the recommended specs?”
    • “This is 2025; I shouldn’t be seeing worse performance here than in much more demanding titles.”
  • grinding

    7 mentions Positive Neutral Negative

    Grinding in the game can become tedious due to repetitive backtracking and lack of saving, making it frustrating to return to previous points after dying. The unchanging map layout adds to the monotony, and crafting, especially mass production like bullet-making, could benefit from quality-of-life improvements. Players appreciate the cooperative aspect and resource gathering but desire more variety and streamlined mechanics to reduce grind fatigue.

    • “But as you understand the map, it can become more tedious to keep repeating the exact same section over and over just to get back to a map you last died on.”
    • “Because once you played enough and remember all map, you may get bored by how tedious the gameplay and map of this game can be.”
    • “It would be even better if the maps have a bit of randomization or different layouts to not be a bit tedious every time when playing the same map.”
  • humor

    4 mentions Positive Neutral Negative

    The game's humor shines especially during online play with friends, where chaotic moments and panicked in-game voice chat create a fun and entertaining experience. Despite some bugs and glitches, these humorous interactions add to the game's engaging and intense atmosphere.

    • “Play with friends online is funny.”
    • “I really recommend this game, this game is so fun, intense, and funny at the same time if you play with friends.”
    • “Using the in-game voice chat made everything so much better, those panicked calls over the radio when we were one step away from dying had us both stressed and laughing.”
  • emotional

    2 mentions Positive Neutral Negative

    Users express strong frustration and anger towards certain game mechanics, particularly time-limited missions and difficult safes, which they find overly punishing. However, they also appreciate the game's replayability and procedural elements that keep each playthrough feeling fresh.

  • character development

    1 mentions Positive Neutral Negative

    Character development is limited, with few customization options available—only three body types, five head types, and about eight colors—leading to a lack of variety and personalization. Users also suggest adding more voice options to enhance character individuality.
