Alexander the Great is the sequel to the strategy game, Genghis Khan. Complete missions by invading territories and winning battles. Purchase units and place them on the staging area before each battle. Once you're satisfied with your army's formation, you can send them into battle by clicking on the fight button. When engaged in a battle, you can still deploy units, and also repair units that are fighting. Conquering territories and completing missions will give you gold, which will allow you to build a stronger army.
