Derived from the Populous engine but presented using a 3-dimensional game map. The player starts out on each map with a small number of soldiers, and maybe a few towns already under control. To win the map, the balance of power needs to be tipped completely to the player's side (represented by a scale below the mini-map), by conquering all (or at least most) of the towns on the map, and killing any opposing captains. Once a town is under the player's control, locals can be drafted into the player's army and bigger towns or enemy armies can be taken on. Some of the bigger towns also have neutral captains and if these survive the battle they come under the player's command as well. In 1991 an expansion set (for computers only) was released that changed the setting from the conquest of a medieval kingdom, to World War I. The game play was still essentially the same, but with more ranged weapons and war-machines.
