R.E.P.O., the thrilling horror co-op game inspired by Lethal Company, is already gaining a dedicated player base. And where there’s a growing community, there are mods! Whether you want more stamina, new monsters, or just some fun tweaks, modding R.E.P.O. is a great way to customize your experience. In this guide, I’ll show you exactly how to install mods for R.E.P.O. in just a few simple steps. Let’s dive in!
How to Install Mods
Just like in any game, mods in R.E.P.O add new content, unlock fresh features, and improve gameplay. Some can enhance stamina regeneration, introduce new monsters, or even expand lobby sizes. The game is still new, but more mods are coming out every day!
Getting the Thunderstore Mod Manager
To keep things simple, you should use Thunderstore Mod Manager, the easiest way to install mods for R.E.P.O.
- Go to Thunderstore.io.
- Click the “Get App” button.
- Download and install Thunderstore Mod Manager.

Settings Up Your Game Profile & Installing Mods
After launching Thunderstore Mod Manager, search for R.E.P.O. (make sure to include the dots: R.E.P.O.). Create a new profile—you can name it something like “REPO Modded”—and select it to activate.
Inside Thunderstore Mod Manager, click “Get Mods” to browse available mods. Pick a mod you like—maybe one that enhances stamina regeneration—and click “Download” followed by “Download with Dependencies” to make sure everything works correctly. Once installed, you can manage your mods under “My Mods”, enabling or disabling them as needed.

Syncing Mods with Friends & Launching R.E.P.O with Mods
If you want your friends to have the same mods as you, go to the “Server” section and copy the mod profile code. Your friends can then go to Profile Selection, click “Import from Code”, and paste the code to install the exact same mods.
When you’re ready to play, click “Modded” in Thunderstore to launch the game. If a command prompt (CMD) window pops up, that’s a good sign—it means the mods installed correctly. Once in-game, test out your mods, like checking if stamina regenerates faster or if any new content appears.

Wrap-Up & Fixes
If R.E.P.O. doesn’t appear in Thunderstore, double-check that you typed the name exactly as “R.E.P.O.” with the dots. If you get an error saying “game folder could not be found,” check Thunderstore settings and manually set the correct game folder path. If your mods aren’t working, make sure all dependencies are installed or try launching the game once without mods before enabling them again.
Also, some mods allow tweaks in their config files, so if a mod feels too strong or not quite right, you can modify its settings. You can also try alternative mods that offer different adjustments if one isn’t quite to your liking.
And that’s it! Now you know how to install mods in R.E.P.O. and customize your gameplay. While the modding scene is still small, more content is being added daily. So go ahead, experiment with different mods, and make your R.E.P.O. experience even better!
