REPO delivers a high-energy cooperative horror experience where up to six players explore eerie locations full of unpredictable encounters. For those seeking to push the chaos further—whether through enhanced cosmetics, larger teams, or inventive gameplay mechanics—the REPO modding community offers a rich selection of custom content. Adding these mods to the game doesn’t require advanced skills, just the right tools and guidance.
Installing Mods With Thunderstore Mod Manager
The most efficient way to manage REPO mods is through Thunderstore Mod Manager, which runs on the Overwolf client. This user-friendly software streamlines everything from finding to updating mods. Begin by downloading the Overwolf platform, then install the Thunderstore App.
After installation, launch Thunderstore Mod Manager and search for REPO. Once the game is located, use these instructions to install your preferred mods:
- Navigate to the “Get mods” section.
- Browse or filter mods by category, or search by name if you know what you’re looking for.
- Select a mod to view its details, then press “Download.”
- Choose the most recent version to ensure compatibility and click “Download with dependencies.”
- Once downloaded, it will appear under “My mods.”
- To launch the game with your installed mods, click the “Start modded” button in the top-right corner.
Prerequisite: Installing BepInExPack First
Before using any mods in REPO, the BepInExPack mod must be installed. It’s a core framework required for most mods to function properly. This essential file is prominently pinned at the top of the “Get mods” section within Thunderstore and should be the first mod installed.

Enabling Multiplayer With Mod Support
If you plan on sharing your modded REPO experience with friends, Thunderstore makes it simple to synchronize configurations. Follow these steps to make sure everyone in your group is on the same page:
Sharing Your Mod Profile:
- Open Thunderstore.
- Click the “Share” button at the top.
- Copy the unique profile code that appears and send it to your friends.
Joining a Modded Multiplayer Session:
Your friends will need to:
- Install Thunderstore if they haven’t already.
- Click “Change profile” in Thunderstore.
- Select “Import/Update” followed by “From code.”
- Paste the code you provided.
- Choose to create a new profile or update an existing one.
Thunderstore will then handle downloading and installing the correct mods automatically. Once complete, launching REPO through Thunderstore will allow them to play with the same setup.
