Age of Empires II: The Conquerors

Age of Empires II: The Conquerors expansion (sometimes abbreviated to AoC) is the expansion pack to the 1999 real-time strategy game Age of Empires II: The Age of Kings. The Conquerors is the fourth installment in the series by Microsoft Game Studios and Ensemble Studios. It features five new civilizations (the Aztecs, Mayans, Spanish, Koreans, and Huns), four new campaigns, eleven new units, twenty-six new technologies, new gameplay modes, new maps and different minor tweaks to the gameplay.

The Conquerors expansion also introduces various new gameplay features and tweaks, including the new game modes "Defend the Wonder", "King of the Hill" and "Wonder Race". Additional maps, some based on real-life geographic locations, and new winter and tropical terrain textures are included. In-game, infantry are able to garrison in battering rams, protecting the infantry while increasing the ram's speed and attack, while ships are able to form formations for more effective fighting. The graphics are the same, but new civilizations have been added such as the Spanish and the Huns.

Micromanagement is made easier, by an improved scripted Artificial Intelligence of villagers and siege weapons. Villagers will now commence automatically gathering resources, if they build resource gathering sites, while siege onagers will not fire if their attack is likely to harm friendly units. Additionally, an in-game option has been added to allow the game to automatically replenish farms after they are exhausted (for the same price as constructing a farm the ordinary way). Chat commands are introduced, in order to communicate more effectively with allied computer players.

For a further refinement, you can also update it with a patch or from a "Gold Edition" which improves and rebalances the game by resolving the "farm bug" and increase the farm capacity to forty.
