The game features a new faction, Angmar, bringing the total number of playable factions to seven. It also comes with a new campaign based on Angmar, consisting of eight missions telling the rise of the Witch-king of Angmar and the fall of the kingdom of Arnor.
New units were added to all six existing factions, as well as both new and improved buildings and heroes. Every faction except Angmar also received an elite hero unit. Elite heroes have a small amount of health and a large amount damage, but there are a small amount of them in each battalion. They only replenish their numbers in a healing structure.
