World at War: A World Divided brings you back to the dawn of the greatest and most terrible war the world has ever seen. The forces of the Axis, including Germany, Japan and Italy, face the might of France, Great Britain, The United States, China and the Soviet Union in the epic struggle of World War II. The course of war is determined by your actions as the leader of one or more major factions, opposed by human or computer players. A World Divided takes this conflict one step further, with a future what-if scenario that occurs right at the end of the war. This new scenario of an early Cold War truned Hot allows players to go continuously from the end of World War II into a new conflict, with the Soviet Union's land army powerhouse and consolidated position against the Western Allies.

The story line for A Nation Divided is relatively short, spanning twelve levels based on some of the most well known battles of the American Civil War. One can play as either the Confederacy or the Union. The player plays as a different soldier during each battle.
