From Electronic Arts: The Lord of the Rings, The Third Age allows players to adventure through Middle-earth, building a party of heroes as they journey. Players battle on the side of the Fellowship, but can unlock additional encounters where they fight on the side of Sauron as they progress. In the game, players will interact with the characters of the Fellowship in a unique structure, taking on individual quests while intersecting the major events of the film trilogy that drive the story forward. Parties will traverse through both familiar and seldom-glimpsed locations, using an innovative turn-based battle system as they fight, encountering the demonic Balrog in the Mines of Moria, defending the fallen city of Osgiliath, or trying to destroy Helm's Deep.
