Based on the popular Civilization franchise, Sid Meier's Civ IV: War of Two Cities brings the excitement of world domination to BlackBerry. Defend the safety and development of your home city while at war with a neighboring city bent on your destruction. Armies will clash, defensive walls will crumble, great siege cannons will roar with fury, and the victor will plant his flag atop the tallest building in the city of his foe.
