Right from the history channel website
DECISIVE BATTLES is hosted by Matthew Settle (Band of Brothers) on location at the ancient battlefields and features expert commentary from the world's foremost historians.
Here's the game website
DECISIVE BATTLES is unlike any series The History Channel has ever aired. Employing the same advanced computer gaming technology as in the highly-anticipated new video game Rome: Total War™ , the series gives viewers an unprecedented perspective of ancient battles by re-creating troops in their vast numbers and landscapes on a scale otherwise impossible. Instead of recounting these ancient battles though drawings, paintings and reenactments using actors, they spring to life in this new computer animation that allows viewers a gods-eye view of the battlefield with its massive numbers of troops, their formations, and the weapons and strategies each side employed. Viewers will get the vantage point the generals wish they’d had.
