🎯 Tips & Tricks
Place FOSE files in your Fallout 3 root directory, not the Data folder, and run fose_loader.exe to start the game.
Check if the mods you want require a specific FOSE version; match the version to avoid crashes.
If you use a mod manager, some support FOSE integration—look for 'FOSE' options in the launcher settings.
