Mimics

Mimics Mod for R.E.P.O

Mimics adds a voice-mimic mechanic to monsters in R.E.P.O.

They can replay random phrases recorded during gameplay, making it harder to trust what you hear.

📖 Description

Think that was your teammate calling for help? Think again.

Mimics brings a Skinwalker-style mechanic into R.E.P.O by allowing monsters to mimic player voices using random recorded phrases.

🎯 Who Needs This Mod

Both Host and Clients need to install this mod to work.

🧩 Compatibility

This mod is incompatible with mods:

• Disable Noise Reduction by SVRZ, as it relies on the game's built-in noise reduction to capture audio and send chunks to other players correctly.

✨ Features

• Monsters mimic player voices recorded during the current session
• In multiplayer, all players hear the same mimic clip on the same enemy at the same time
• Voice can be played back with a random pitch or alien filter — the host decides which, so all players hear the same effect
• Custom audio support — drop your own.mp3,.wav, or.ogg files into the custom-audio folder to add more sounds to the mimic pool
• Mod authors can register custom clips at runtime via the public MimicsAPI

🧭 Roadmap

Planned: context-aware audio playback linked to gameplay events, for example:

• Enemy sees player
• Enemy hits player
• Player death / damage
• Item destroyed

Goal: make mimic behavior feel more believable and tied to events, instead of only random timing.
