Four New Campaigns
Alaric: The trauma of the Hun invasion in the 4th century has shaped Alaric, the fearsome warrior king of the Goths. But can the beloved king secure a new homeland for his people in the territory of the collapsing Roman Empire?
Sforza: Always hungry for glory and wealth, Sforza wanders around 15th century Italy, offering his services to the highest bidder. Will he pick the right battles or make the wrong enemy? Take the fate of the young mercenary captain in your hands.
Bari: 400 years after the collapse of the Roman Empire, Italy is still up for grabs. Relive the tale of the port city Bari from the point of view of a Byzantine family, rising from the common soldiery to the nobility. Beware, for not only Bari is at stake, but also control of Southern Italy.
Dracula: History forged an incredible legend around the man who ruled Wallachia in the mid-14th century. Holding his ground against the vast armies of the expanding Ottoman Empire, his cruel tactics made him the most feared man in all of Eastern Europe. Shall his thirst for blood and the loyalty of his soldiers hold the Turks back for good?
