Gameplay
The game retains the basic mechanics of real-time strategies. Warring factions gather resources, then use them to construct military bases and armies on-site. In Battle for Middle-Earth, buildings may only be constructed on the building slots of predefined plots. Plots range from farmhouses to full-fledged castles, with different slot arrangements and available buildings, and plots can be purchased when they're in the sole presence of a side's forces. The only resource are the nebulous "resources," which are produced inexhaustibly in dedicated buildings.
Four factions on two sides wage the War of the Ring: Representing the Free Peoples are the horse-lords of Rohan, and Gondor with its forges and battlements. The Forces of Darkness are the fighting Uruk-hai of Isengard, and Mordor's orc hordes, bolstered by Haradrim, Mûmakil and Trolls.
Keeping with the trends of contemporary RTS titles, basic units operate in groups, significant characters are represented by "hero units" as popularized by Warcraft III, and the destruction of units gathers points for the purchase of special abilities. There is also a unit limit.
Unit strengths and weaknesses form a sort of rock-paper-scissors system. Cavalry beats archers as they do not have a lot of time to fire and are then forced to close quarters fighting, Pikemen beat cavalry, swordsmen beat pikemen and archers beat swordsmen. Fire beats Ents, Mumakil, and Trolls. Units gain experience and levels, becoming hardier and more dangerous. Squads replace lost members when rank 2 or higher without losing experience.
Most normal units have purchaseable upgrades and may also have abilities such as changing formation, changing weapons, combining with other squad types, Ranger stealth and orc cannibalism. Heroes are unique, far more potent units (and Hobbits and Gollum) that lack upgrades but do have multiple, elaborate abilities, and can be purchased back if killed. Most hero abilities require certain experience levels. Good has the advantage in the quantity and quality of heroes; Gandalf at the peak of his strength is an anti-army device. Buildings also gain experience and may become able to build new units, research new upgrades, or bestow better passive bonuses such as a reduction in cavalry build costs.
The player's special powers are purchased from a small tree. They can be utilitary (Vision of the Palantír, reveals an area), supportive (Healing), or able to call in temporary units (Summon Eagles, Summon Balrog). They are usable indefinitely once acquired, with recharge times but no cost. Both factions on a side share the same powers, and the tree is much larger (and slower to climb) in campaign mode than it is in skirmishes. Good has some powers that boost the ability of a single hero (Power of the Istari, Andúril). Evil receives aid in resource harvesting (Industry, Fuel the Fires).
A feature used in the game is Pie menu which makes gameplay easier especially for novices.
The Heroes for Gondor are Pippin, Faramir, Boromir, and Gandalf. Rohan's heroes are Merry, Eowyn, Eomer, Theoden, Gimli, Legolas, Aragorn, and Treebeard (he is bought at an Entmoot). Isengard's heroes are Lurtz and Saruman. Mordor's heroes are Gollum, two Nazgul, and the Witch King of Angmar.
