New York (NY) - A special edition version of Civilization IV will make its way to stores later this month, offering an "impressive list" of exclusive bonus items.

The new bonus edition of the game includes the Civilization IV : Warlords expansion pack, as well as a handful of supplemental material designed specifically for the Gold Edition.

A general "fantasy-style" poster from legendary Sci-Fi artist Greg Hildebrandt, a behind-the-scenes DVD, and a Tech-tree poster will be included in the deluxe set.

Civilization IV first went on sale on October 25, 2005, as the latest installment to the strategy game series that has now sold more than eight million copies.

Civilization IV : Gold Edition will begin shipping on July 17, with a list price of around $50.
