In a twist of fate, the U.S. Army is forced to begin major landing operations on what was once its own soil. In this low-tech era, there is one weapon class that will determine the course of the war: the Vertical Tank (VT). Playing as pilot Lt. Powers, control one such unit as he embarks on a mission where the action shifts from North America to battlefields and war-torn streets across the globe.
