Empire Earth II, also called EE2, is a real-time strategy computer game developed by Mad Doc Software and published by Vivendi Universal Games on April 26, 2005. It is a sequel to the 2001 bestselling game Empire Earth, which was developed by the now-defunct Stainless Steel Studios. The game features 15 epochs and 14 different civilizations.
The game has three playable campaigns: a Korean, German, and American one, as well as several other playable scenarios. The game received a mildly positive reaction, earning a 79% average rating on GameRankings. An expansion pack, which was released by Mad Doc Software called Empire Earth II: The Art of Supremacy, was released on 14 February 2006.
Empire Earth II has several new gameplay features from the original gameplay of Empire Earth, such as the Picture-in-Picture window, a small window within the game interface which allows the player to control activities such as unit and building construction. The Citizen Manager can be configured to tell a citizen what to do if they have no set task, and the Diplomacy System allows the player to make tributes and manage alliances and wars with other players. The War Planner is another new addition, which is a map of the game that the player can display and use to coordinate attacks with allies. The crown system grants strategic bonuses to players who are first to master an epoch's military, economic, or imperial paths at the cost of losing a faster age progression. Weather, another new feature, changes over time on the map and affects the look of the map and performance of units and, in the case of airplanes in thunderstorms, hit points.
Besides campaigns and special scenarios, there is also a skirmish mode where the player can play against a computer player. The player can also play against other human players, however, the common EULA clause that each player needs his own copy of the game is actually enforced, even for LAN games. Unlike campaigns or scenarios, the winning conditions never change. There are eight different game modes in skirmish mode, which can also be played in Multiplayer. The multiplayer servers were taken offline on 1 November 2008, after which players can only play through local area network and with gameranger.
There are 15 epochs in the game, each representing a part of history. As the player advances through the epochs, new and improved units and structures become available. Some of the epochs in EE2 are identical to their counterparts in the original Empire Earth—one exception is that EE2 does not allow players to expand their empires into space. The epochs are the Stone Age, Copper Age, Bronze Age, Iron Age, Dark Ages, Middle Ages, Renaissance, Imperial Age, Enlightenment Age, Industrial Age, Modern Age, Atomic Age, Digital Age, Genetic Age and Synthetic Age.
Before buildings and units can be made or created, resources must be gathered. There are two kinds of resources: main resources and special resources. The main resources are available in all epochs and they are food, wood, gold, and stone. To collect resources, a citizen (or a band of citizens) is selected, and are directed to a resource. The citizens thus begin harvesting it.
The special resources are available in only some epochs. These special resources are tin—available until epoch 6, iron—first available in epoch 4 and is no longer used after epoch 9, saltpeter—first available in epoch 7 and is used until epoch 12, oil—first available in epoch 10, and uranium—first available epoch 13.
EE2 has technologies to improve each player's civilization. Technologies are divided into three groups. The first is Military, which provides benefits mostly to military units. The next is Economic technologies, which increases resource gathering rate, decreases cost and building time for units and buildings and decreases tribute tax amount. The final group is Imperial, which provides benefits mostly to special units and increases the health of units and buildings.
There are four technologies of each group for each epoch. Technologies can be researched by spending tech points. To get tech points, an appropriate number of citizens must be garrisoned in a university and/or an appropriate number of priests must be garrisoned in a temple. Technologies are researched through the main interface (no longer through a building) by clicking the Technology Tree button. When the correct amount of tech points are available, the tech tree button will light up and a new technology to research can be chosen. However, when research is no longer used (at the highest epoch specified before starting a game), the garrisoned units will become idle.
In EE2, each civilization belongs to a particular world region, each having its own regional powers. These can be activated on the game interface by clicking on a special button. All of the regional powers are timed; once the time is up to use it, it takes a long time for the regional powers to be recharged to use again. Each regional power can only be used in a respective group of epochs. For example, the regional power of 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, EE2 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 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, and Korea. Finally, the Meso-American civilizations are the Aztecs, Incas, and the Mayans.
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 Mexico, 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.
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 conqust over the other Korean states. The last scenario for this campaign is the final war with China.
The German Campaign deals with the years between 1220-1871 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 reunification of Germany under Otto von Bismarck.
The American Campaign is part-fact and part-fiction, set between 1898 and 2070. The first scenario is about the Spanish–American War in Cuba, followed by one about the Meuse-Argonne Offensive in World War I. The scenarios are about World War II, featuring the North African Campaign and a fictionalized version of the Ardennes Offensive. These are followed by Cold War spy missions against the Soviet Union. The next scenarios are fictionalised, about an attempted coup lead by a disillusioned General Charles Blackworth against the US government; the player is charged with stopping this coup, eventually engaging Blackworth and his followers in the Amazon Rainforest. When the player wins the last scenario in this campaign, there is a short film about mankind and the Earth. When that film ends, the credits for the game are shown.
There are four special scenarios in Empire Earth II called turning points. These scenarios can be played from either side of a battle or war which changed the course of history. The Normandy scenario takes place during the D-Day invasion, where the player can play as the Americans to repeat the success of Operation Overlord, or play as the Germans to stop the Allied invasion force from breaching the Atlantic Wall. The Three Kingdoms recreates the period after the end of the Han Dynasty, where the player can play as the Kingdom of Wei or the Wu Kingdom, either winning historically as the Wei or changing history as the Wu.
