The Hobbit Dwarf Units PATCH's aim is to bring the look of the dwarves from the Hobbit movies to MOS 1.7. Install this submod by extracting the modfile in your Third_Age_3 folder, or its equivalent if you have renamed the Third_Age_3 folder to something else. Overwrite files when asked to do so. Note: The Hobbit Dwarf Units PATCH mod is not made by the MOS team and they will not support it. Also you will not be able to undo the install of the mod, unless you made a backup of the files it overwrites before you installed it.
