Sid Meier's Civilization IV: Warlords includes new civilizations, leaders, units, resources and wonders that offer even more fun and exciting ways for players to expand their civilization's military power as they strive for world domination.

Sid Meier's Civilization IV: Warlords adds new twists and challenges to some of the most creative scenarios in the series. In the Omens scenario, Great Britain and France race to settle North America at any cost, while the Barbarians scenario allows players to take control of ruthless hordes of warriors. With these brutal Barbarians under your control, your goal is to conquer all other civilizations on the map by decimating their armies, looting the cities and burning them to the ground."
