Wars of the East is a large-scale modication for The Battle for Middle-earth: The Rise of the Witch-king. It adds 2 new playable factions, over 140 new units/heroes, new structures, new skins, new powers and more!
When I try to save, or try to recruit Gil-Galad, or try to play more than half an hour, or create a custom hero, or recruit a custom hero, the game crashes. Apart from that, it's a decent mod.
