There are two types of heroes, Strategist heroes who heal surrounding units and can demoralize enemy units while Warrior heroes give morale to surrounding units and have a greater attack power. Heroes can be built at the town center or capital. The game itself contains many unique and innovative features, including a 'morale' system, which directly affects individual units statistics.
Empire Earth uses 3D graphics instead of sprites like Age of Empires II, the comparable game at the time. Empire Earth is similar to the Age of Empires series in that it is a history-based real-time Strategy Game.
