Darnified Ui Fallout 3 How To Install Darnified Ui Oblivion This mod gives the Oblivion UI the most extensive facelift yet. This ensures that all new features that are added to FOMM will be available for both games. Instead of having two different managers, one for Fallout 3 and another for Fallout: New Vegas, FOMM is able to manage mods for both games from a single install. This version of FOMM is the first step in expanding the scope of the mod manager.
