Mordor, and East, had unique origins, loyalties, and characteristics. Half-Orcs, bred from evil Men and Orcs, played a significant role in battles alongside Uruk-hai and other subtypes like Snaga.

Players will also gain access to other Factions units - like Mordor being able to use the Uruk-hai of Isengard - but each Faction will have a unique unit that can not be used by any other.
