💡 Beginner Tips
- Since the mod is from 2009, make sure you're playing Fallout 3 with the latest unofficial patch to avoid conflicts.
- Check the mod's file structure—if it's a .esp, place it in your Data folder and enable it in the launcher.
- Test the weapons in a save before committing—arm-mounted animations might clash with certain armor or power armor.
