Empire Earth is a real-time strategy video game developed by Stainless Steel Studios and released on November 13, 2001.

The game requires players to collect resources to construct buildings, produce citizens, and conquer opposing civilizations.

[4] An expansion pack, Empire Earth: The Art of Conquest, was developed by Mad Doc Software and released in 2002.

[6] The game itself contains many unique and innovative features, including a "morale" system, which directly affects individual units' statistics.

Civilizations are predetermined in scenarios but chosen by the player shortly after the beginning of random map games.

With the exception of the futuristic Novaya Russia and Rebel Forces, all civilizations in Empire Earth are based upon history.

From the Prehistoric to Dark Ages, the civilizations are Ancient Greece, Assyrian Empire, Babylon, Byzantine Rome, Carthage, and the Kingdom of Israel.

This part is about Alexander's ascension to the Macedonian throne and the establishment of the League of Corinth by crushing the revolt of Thebes, Athens and Sparta.

The first three scenarios (of eight total) are about William I of England, his victory against the rebellion from the barons with the help of Henry I of France in 1047, and the Battle of Hastings in 1066.

The sixth scenario is about Henry V of England's story, some parts based on William Shakespeare's play.

The final two scenarios are led by Arthur Wellesley, 1st Duke of Wellington, who meets Napoleon I of France in battles at Roliça, Talavera and Waterloo.

In the German campaign, the first four scenarios—out of seven total—take place during World War I and feature the Manfred von Richthofen, the Red Baron.

The second part, consisting of three scenarios, deals with Nazi Germany and the first years of World War II in Europe.

The first scene introduces the Blitzkrieg, in which the player has to conquer Poland, Scandinavia, and France before an American-Soviet alliance makes it impossible.

In the final scenario—the never-attempted Operation Sealion—the player leads German forces in an invasion of Great Britain under the famous Field Marshal Erwin Rommel, ultimately annexing the United Kingdom to the Greater German Reich and thwarting a surprise attack by the U.S. 5th Fleet (led by the carrier USS Enterprise) in the process.

The game begins in 2018, with the Russian political dissident Grigor Stoyanovich heading up a full-sized civil war from Volgograd, followed by a seizure of power in the Kremlin in Moscow.

In the third scenario the now-old Grigor appoints his robotic bodyguard as his successor, crushes a coup in Moscow with help from loyalist forces, and finally succumbs to heart problems.

In the penultimate scenario, during an attempted invasion of the United States in 2098, General Sergei Molotov finally realizes that Grigor II became mad with power, and deserts instead of following orders to wipe out the entire population of Cuba.

Cooperating with U.S. agent Molly Ryan, he re-enacts the Chinese plan, building a time machine and returning to 2018 in order to set things right.

In addition, Grigor II realized their plans and took the time machine, fortifying Volgograd with a sizeable detachment of cybernetic forces.

They mentioned many aspects of the game, including the use of heroes, unit upgrades, the availability of civilizations, economic build-up, and polishing of the final product.

[11] On January 18, 2001, Stainless Steel Studios added Damon "Stratus" Gauthier to work on the multiplayer aspect of the game.

Empire Earth also made appearances at E3 2000 and E3 2001 about its progress, and a beta test and movie for it were released in early August 2001.

"[23] GameSpot was not as impressed, giving it 7.9/10, saying "Empire Earth is best reserved for hard-core real-time strategy players who won't mind the game's less-than-stellar graphics and sound but will instead relish the ability to relive 14 different epochs of human warfare.".

Empire Earth II was developed by Mad Doc Software and published by Vivendi Universal Games.

[24] The community has been maintained in part by sharing custom scenarios and various creations such as textures and 3D models, but mostly by projects that have helped the game evolve over time.
