When a player has enough food and gold to advance to the next age, the player must wait. After about a minute, the city reaches the next age. The player's buildings look different and the player can do new things to improve his town and soldiers. New, powerful soldiers such as archers (people that shoot with a bow and arrow), cavalry (warriors that ride horses), catapults (machines that throw stones), artillery (big guns that shoot cannon balls) can be used. The player can build walls and towers to defend the city. The player can even build many different Wonders that give different effects.
