The original UMS has been extensively developed to allow you full control over entire Nations At War. Across land, sea, and by air, relive the battles of Alexander the Great, the Napoleonic Wars, and the D-Day landings of 1945. Up to 50 players can wage war simultaneously. Your sphere of control encompasses all aspects of military command, from the strategic planning of campaigns across continents to issuing battle orders to small units of field troops. Utilization of accurately simulated military hardware, enduring the rigors of battle through extremes of climate, and a total awareness of the politics of warfare must be learnt for success. The chance to re-write history is in your hands.
