  • Open Fallout Tactics installation folder by going to System Disk > Program Files (x86) > Steam > steamapps > common > Fallout Tactics.
  • Look for “BOS.exe” in it and create a shortcut in desktop.
  • Right-click on the Fallout Tactics shortcut that you created and choose “Properties“.
  • Add “-g” command at the end of shortcut target and press Apply.
