Captain Patrick "Archangel" Stone accepts a covert assignment from the OSS during World War II, commanding elite forces through pivotal campaigns spanning both European and Pacific theaters. As a seasoned commander, players orchestrate tactical operations across historically significant battlefields—from the beaches of Normandy to the islands of the Pacific—directing troops into combat while wielding an authentic arsenal of period weapons and explosives. The campaign demands versatility beyond infantry combat, requiring players to transition between ground operations, armored tank warfare, and aerial dogfighting as circumstances demand. Each mission tests leadership and firepower in equal measure, calling on the player to adapt strategy and leverage whatever tools prove necessary to complete objectives and neutralize enemy threats.
