Civilization IV Warlords

Sid Meier's Civilization IV: Warlords is the first expansion pack to the 2005 Game of the Year-winning 4X. The expansion pays homage to history's greatest military leaders with a new great person type, the Warlord, and adds vassal states letting you subjugate conquered enemies under your rule rather than annexing them outright.

Six new civilizations join the roster with their unique units and buildings: the Carthaginians, Celts, Khmer, Ottomans, Vikings and Zulu. Ten new leaders ship across the new civilizations and previously existing ones, including Genghis Khan, Hannibal Barca, Boudica, Suryavarman II, Suleiman, Ragnar Lodbrok, Shaka and others. Two new leader traits and three new wonders supplement the core mechanics.

Eight historical scenarios provide curated content beyond the base game: Rise of Rome, Alexander the Great, Genghis Khan, Vikings, Chinese Unification, Peloponnesian War, American Revolution and Omens. Each unique civilization gains a unique building alongside the unique unit. The expansion bundles all previously released patches and game upgrades (including Pit Boss server tools) for the core game, and tweaks several base systems for improved balance.
