    The gameplay offers deep, complex mechanics with a unique asymmetrical combat loop between marines and xenomorphs, providing a highly replayable and evolving experience. However, it suffers from a steep learning curve, repetitive game modes, occasional mechanical imbalances, and frustrations stemming from a strict or inconsistent administrative approach. While enjoyable and addictive for dedicated players, the gameplay can be hindered by community and staff-management issues.

    • “CM-SS13 is a descendant of the cult classic game SS13, spinning the engine from a social deduction murder mystery experience into an asymmetric TDM game with an unbelievable amount of depth and width in its mechanics and how they interact.”
    • “It's also completely open source, community coded, administrated, and more, which means the game is always mechanically changing and can be incredibly addictive; there's almost always enough new stuff to rope you back in with the joy of discovery.”
    • “Being in the CIC coordinating troop movements and responding to xenomorph threats is some of the most unique gameplay I've ever been a part of.”
    • “Gameplay might seem novel at first, but it gets extremely repetitive because the only thing that changes between rounds is the map. There's only one game mode, and even after a few years, instead of adding more content, they've only removed more and more content. If you're not from the US, you're going to have bad ping even with relay systems, which negatively affects the gameplay.”
    • “I didn't have much of a problem with the staff nor did I grief, but it's annoying that you can be potentially interrupted mid-game with an 'admin notice' where you have to reply or 'explain' yourself, and have to keep talking to them until they leave you alone. It's quite humiliating that you are forced to explain something even if you didn't negatively affect anyone's gameplay.”
    • “The gameplay loop is solid; however, the staff/admins are and will be the downfall of this server and servers that are in a similar state of zealous control freaks. Somehow they're more insufferable than when Feweh was around.”

  • graphics

    7 mentions Positive Neutral Negative
    43% positive mentions, 14% neutral mentions, 43% negative mentions

    The graphics are deliberately pixelated, giving the game a distinctive, retro aesthetic that some find charming but others see as outdated or niche. While the visual style may be an acquired taste, improvements have been made over time, though the UI and controls initially feel clunky. Overall, the graphics suit the game's unique style but might not appeal to everyone.

    • “It's great fun, but there are annoying reminders as to why this game is so niche; you can see the individual pixels on the screen (though personally I think the aesthetic is used quite well).”
    • “Overall great game, the graphics and UI are definitely an acquired taste though.”
    • “I think that I have had less lag and also the graphics have gone up tenfold.”
    • “I think that I have had less lag and also the graphics had went up ten fold.”
    • “But I wish to warn parents and other people unwilling to have anyone think this game is safe for their kids to play when it should be labeled with the risks from BYOND and servers that contain pornographic themes of anything, or could be added with some code work.”
    • “Every single negative review I've read so far, with only a couple discussing the overall balance of the game, has focused on issues that are six years old, and I say this confidently with nearly a year of coming back because TGMC was outright boring and RMC14 not having the aliens aesthetic.”

  • story

    3 mentions Positive Neutral Negative
    67% positive mentions, -34% neutral mentions, 67% negative mentions

    The story incorporates role-playing elements that enable collaborative storytelling, allowing players to assume roles like a researcher uncovering new chemicals and equipment. While some may find this approach unconventional, it adds depth and engagement to the narrative.

    • “On top of this, there are also roleplay elements present, which allow for collaborative storytelling that you might end up liking.”
    • “You can play as a researcher, trying to unlock new chemicals and equipment to aid the mission.”
    • “Join the community forums (same story).”
    • “On top of this, there are also role play elements present (cringe I know), but they allow for collaborative storytelling which you just might end up liking.”

  • humor

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

    The humor in this community is often seen as immature and cringeworthy, particularly related to specific player groups like xenomorph users who engage in awkward roleplay and exhibit poor sportsmanship. This has led to negative experiences and even bans over previously accepted jokes, making the overall humor unwelcoming for some players.

  • optimization

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

    The game is well-optimized to deliver intense, impactful gameplay within relatively short sessions, allowing players to significantly influence their team's performance.

  • replayability

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

    The game's replayability is strong due to its enjoyable gameplay loop and immersive military roleplay in a sci-fi setting, though the extremely difficult barrier of entry may limit its accessibility for some players.

  • stability

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

    The game’s stability is notably lacking, characterized by frequent bugs and an overall unpolished feel consistent with the classic SS13 experience.

    • “It's also, in classic SS13 style, perpetually in a state of unpolished bugginess.”

  • music

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

    The music in the game closely replicates the original film and licensed game soundtracks, enhancing the authentic atmosphere with familiar and iconic audio elements.
