How To Install Mods In Far Far West - Step By Step

If your Far Far West game keeps crashing or your save files are disappearing after you try to install mods, you are likely running into compatibility issues with the latest Unreal Engine 5.7 update. Installing mods the old way with generic tools often corrupts your save data, so follow these steps to keep your game stable.

Why this happens

Far Far West runs on Unreal Engine 5.7, which requires specific byte-pattern configurations that standard mod loaders cannot handle. Using the wrong file structure or outdated UE4SS builds will cause instant crashes or permanent save corruption.

What you'll need

Make sure you have the latest .NET runtime installed and a fresh backup of your save files. You will also need the UE5.7-specific UE4SS build found on the Far Far West Nexus Mods page.

Steps

1. 01
   Navigate to %USERPROFILE%/AppData/Local/Far Far West/Saved/SaveGames and copy your files to a safe backup folder on your desktop.
2. 02
   For cosmetic or UI mods, navigate to C:/Program Files (x86)/Steam/steamapps/Common/Far Far West/Far Far West/Content/Packs.
3. 03
   Create a new folder named ~build_mods in that directory and move your .pak files inside it.
4. 04
   For gameplay mods, download the UE5.7-specific UE4SS build from the Far Far West Nexus page.
5. 05
   Extract the downloaded files into C:/Program Files (x86)/Steam/steamapps/Common/Far Far West/Far Far West/Binaries/Win64.
6. 06
   To activate Lua mods, open the mods.txt file located in the /Binaries/Win64/UE4SS/mods folder and add your mod's name as a new line.
7. 07
   If using 5 or more mods, download and run the Far Far West Mod Manager (FFMM) from the Nexus page to automate the installation process.
