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

Installing mods in Far Far West can easily lead to a corrupted save file if you aren't using the specific versions required for Unreal Engine 5.7. Because of byte-pattern mismatches, standard modding tools will cause immediate crashes on launch after the May 14th update.

Back up your saves

Before doing anything, navigate to %USERPROFILE%/AppData/Local/Far Far West/Saved/SaveGames and copy these files to a separate location. This is your only recovery option if a mod conflicts with an update.

Why the tilde matters

When installing .pak files, you must name your folder ~build_mods. That tilde is mandatory because it tells the engine to load these files last, allowing your mods to override the base game assets.

Steps

1. 01
   To install cosmetic or UI mods, navigate to C:/Program Files (x86)/Steam/steamapps/common/Far Far West/Far Far West/Content/Packs.
2. 02
   Create a new folder named ~build_mods and move your .pak files inside to activate them.
3. 03
   For gameplay mods, download the UE5.7-specific UE4SS build from the Far Far West Nexus page.
4. 04
   Extract the downloaded files into C:/Program Files (x86)/Steam/steamapps/common/Far Far West/Far Far West/Binaries/Win64.
5. 05
   Navigate to the UE4SS/mods folder, open mods.txt with Notepad, and add the activation line for your specific mod (e.g., "XP Mod 1").
6. 06
   If you are running five or more mods, download and run Far Far West MM.exe from the Nexus page to manage them without manual file editing.

Still not working?

If you are still crashing, check your .NET runtime installation, as the Mod Manager requires it to function. If a specific mod causes a crash after a game update, delete the files in your ~build_mods folder or the specific UE4SS mod entry and check the Nexus page for a version tagged for the most recent game patch.

Frequently asked questions

Will using these mods get me banned?

Far Far West is a single-player title, so there is no anti-cheat software detecting these modifications. However, always keep a clean backup of your save folder in case a mod update corrupts your progress.

Can I use Vortex or MO2 for these mods?

No, standard mod managers like Vortex or MO2 do not handle the specific Unreal Engine 5.7 file structure correctly. Use the manual methods described above or the dedicated Far Far West Mod Manager for stable results.
