Four friends, one tram, and an AI that learns your voice to destroy you from the inside. MIMESIS is the social-horror experiment your friend group needs to fall apart over.

I've been thinking about what genuinely new horror co-op can look like in an era when the genre defaults to jump scares and darkness sliders, and MIMESIS answers with something quieter and stranger: it weaponises familiarity. The threat here is not a monster you can point at and shoot. It is the possibility that the person talking to you in voice chat is already gone. The setup is bleak and deliberate. Four survivors ride an aging tram through a post-apocalyptic world where a cursed rain transforms people into perfect replicas of themselves, called Mimeses. During daylight runs you scatter across procedurally shifting environments, scavenging Scrap, fuel, and spare parts to keep the tram alive. When night falls and the rain returns, the creatures emerge or, more unsettlingly, may already be walking beside you. The resource loop is functional but unambitious on its own. What elevates it is the reinforcement learning AI underneath. MIMESIS listens to your actual voice across a session and builds a behavioral model: the longer you play, the more convincingly the AI can echo your speech patterns back to your teammates. Early in a run it is easy to spot a mimic. An hour in, you start second-guessing people you know. That psychological engine is either the whole game or the only game depending on your crew. Community feedback splits exactly where you would expect. Players who lean into the paranoia, who treat every silence as suspicious and every off-beat response as a tell, report sessions that feel genuinely unlike anything else in the co-op horror space. Critical voices point to the current Early Access state: map variety is limited, the melee combat is barebones with a basic left-click attack and little else to work with, and on short sessions the AI has too little voice data to convincingly deceive anyone. Both complaints feel honest and compatible. This is a concept in progress, not a finished product. The first-person presentation is functional rather than atmospheric. Visually it does not try to compete with higher-budget contemporaries, and the environmental design prioritises legibility over dread. The soundscape does more heavy lifting than the art, and the silence between tram stops carries a real weight when you let it. Comparisons to Lethal Company are fair as a structural shorthand, but the AI deception layer pushes it somewhere Lethal Company never goes: the horror of a mimic that knows your cadence, your jokes, the exact way you say you are safe. For Early Access, the foundation is more interesting than the execution, which is exactly the condition worth watching. ReLU Games is a studio built around deep learning research, and this is clearly a genuine design thesis rather than a trend-chase. If the AI fidelity improves, the map pool expands, and the combat finds any depth at all, MIMESIS has a real claim on its own genre corner. Right now it is a brilliant premise that needs its teammates to show up. Kai, Scout Team

GamerScout Verdict

Best for tight friend groups who want their co-op sessions to end in genuine suspicion - once the AI has enough voice data to earn it.
