of missions, the goal of most of which is to defeat the computer controlled opponent or opponents by gaining possession of their territory, or, in the case of the Dark Tribe, by destroying their temple using gardeners. In the original release of the game, there were three separate campaigns of three missions each (one campaign each for the Romans, Vikings, and Mayans), and a fourth campaign of twelve missions in which the player controls all three races as they fight against the Dark Tribe.
