Game Overview

A broken tram becomes the last fragile shelter in a hostile, rain-soaked nightmare where even your closest teammate may be a predator wearing a familiar face. MIMESIS is an online co-op horror game built around paranoia, voice chat, and the unnerving possibility that an enemy has copied someone in your group perfectly. Its monsters do more than chase players through dark environments: the titular mimics reproduce voices, habits, and remembered details, turning ordinary conversation into a survival tool and a potential trap. The mood is tense rather than action-heavy, with every reunion carrying the fear that the person answering you is not the person you expected.

Each match centers on scavenging the surrounding area for useful scrap and bringing it back to repair an aging tram before the situation collapses. Players need to coordinate searches, manage sudden threats, and make quick decisions when cursed rain or roaming creatures turn a routine supply run into a disaster. A working microphone is central to the design, since listening closely to allies and responding naturally can expose—or conceal—a mimic; headphones make those interactions considerably more effective. Cooperation keeps the team alive, but blind cooperation can be fatal, creating a social-deduction layer without pausing the survival-horror pressure for formal voting rounds.

What separates MIMESIS from standard monster-survival co-op is how directly it weaponizes the group’s own communication. Rather than merely hiding an impostor among players, it makes AI threats capable of performing the role of a friend, so knowledge gained during a run can be used against the team. Unpredictable conditions and changing dangers give repeated sessions a different rhythm, especially with a regular group willing to role-play the uncertainty and communicate constantly. Fans of Lethal Company’s cooperative panic, Phasmophobia’s reliance on voice and atmosphere, or The Thing-style distrust should find plenty to like, while solo players and groups unwilling to use microphones should look elsewhere.

Setup Guide & Troubleshooting

How do I fix missing DLL errors for MIMESIS (v0.2.6 & Multiplayer)?

After extracting MIMESIS (v0.2.6 & Multiplayer), navigate to the _Redist or _CommonRedist folder inside the game directory and install DirectX, Vcredist, and any other dependencies included.

What should I do if the downloaded file is corrupted?

The full archive is 1.40 GB — make sure your download completed fully before extracting. Use 7-Zip to extract the files. If you still see a "file corrupted" error, re-download and try again.

Do I need to run the game as administrator?

Usually, no. Start the game normally from the extracted folder. If you see a permissions or save error, check that the folder is writable and follow the game's documented fix. Only grant administrator access when a trusted game's specific setup requires it.

How do I update my GPU drivers for this game?

MIMESIS (v0.2.6 & Multiplayer) requires a GTX 1050 Ti 4GB / AMD RX 570 4GB or equivalent. Update your NVIDIA or AMD drivers to the latest version for the best performance.

The game won't launch — what should I try?

Check that extraction completed and your PC meets the system requirements. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.

My antivirus is blocking the game — is it safe?

A warning needs to be investigated; the download source alone cannot confirm that a file is safe. Keep your security software enabled and review the detection details. Do not run or restore a flagged file unless you have verified that it is a false positive. If you are unsure, leave it quarantined.
