Sid Meier's Civilization IV: Warlords pays homage to some of the world's greatest military leaders, with six new scenarios, new civilizations, new leaders, more units, resources and wonders. Civilization IV has sold over one million copies worldwide and was voted best strategy game of 2005 by a number of video game publications.

"Civilization IV has been a great success for us," said Christoph Hartmann, Managing Director of 2K Games. "We believe Warlords will exceed the extremely high demands of gamers worldwide with new additions to its already successful formula."

"We're very happy with the success of Civilization IV," said Sid Meier, Director of Creative Development for Firaxis Games. "Within days of its release, gamers around the world were fully addicted, staying up late at night and just hoping for 'one more turn'... what could be better! Warlords will feed that addiction with more of everything gamers want."

Civilization IV: Warlords will of course require the full version of Civilization IV when it's released this summer. For more information check out the Civilization website.
