GTA: Age of Warriors
When the Roman empire was expanding, there is only one group of people that gives them the greatest challenge. These are the Vikings. The Romans got the best weapon and armor, but the Vikings have guts and courage to fill what they lack. The Roman defeated the Vikings and only a few tribe remains, but one leader were able to unite all the tribes to bring down the Romans. The game can only be played with a mouse. You need to gather more gold to be able to produce more warriors to fight for your tribe. As you move from one level to another, you would unlock more powerful warriors.
