The Fall of Mordor is a multiplayer Lord of The Rings mod for Mount and Blade: Warband. Focusing on different scenarios and PvP clanbattles.
Adding Dwarves and Dale, revamping the existing factions, FoM 1.25 is easy to install and play.
There is already an article on this mod's page if you are interested on having an idea of the new classes.
As always, the installation is very simple, no need to overwrite your 1.21, all you have to do is take the FoM 1.25 folder out of your rar file and place it into your modules, simple as that.
I hope you have fun!
