Overtime can only be used by a player using a Far Eastern civilization in epochs 11–15. Like many games before it in the same genre, Empire Earth II has civilizations for players to lead to greatness. Each civilization has a unique power, giving it an advantage in a particular field. Each civilization also has a unique unit, which is a more powerful version of a given unit type. The Greek Hoplite, for instance, is a more effective heavy infantry than the other tribes' counterparts. The western civilizations are the Americans, British, Germans, Greeks, and the Romans. The Middle Eastern civilizations are the Babylonians, Egyptians, and the Turks. The Far Eastern civilizations are China, Japan, Korea. Finally, the Meso-American civilizations are the Aztecs, Incas, and the Mayans. Campaigns Empire Earth II contains three single-player campaigns, a collection of scenarios called "turning points" and a tutorial campaign. The tutorial campaign features the Aztecs, featuring four scenarios to allow players to learn the gameplay. The first scenario is about the founding of the city of Tenochtitlan, followed by a scenario about the Spanish conquest of the Aztec Empire, which ends with the Aztecs driving out Hernán Cortés and his conquistadors. These scenarios are followed by ones about an Aztec alliance with the United States and a war with the Incas, occurring before World War II. Korean campaign The Korean campaign is about early Korean history, from 2333 BC to 676 AD, divided into eight scenarios. The first two scenarios are about the founding of the state of Gojoseon and its first contacts with other Korean states and China, followed by scenarios about Korea's first wars with the Chinese and other Korean states. The next scenarios follow the Korean civil war and the state of Silla's decision to ally with China, and its eventual conquest over the other Korean states. The last scenario for this campaign is the final war with China. German campaign The German Campaign deals with the years between 1220 and 1871 in central Europe. The first four scenarios are about the struggles of the Teutonic Order and the knights' eventual downfall. The next two scenarios are about the rise of Prussia and the Seven Years' War. The next scenario is about the war with Napoleon I of France. The final scenario is about the war with Denmark, Austria and France and the unification of Germany under Otto von Bismarck. American
