The Romans are one of several new factions planned for the game. Others include the Kushan Empire and the Parthian Empire. The Romans will consist primarily of the Legion, a heavy infantry unit armed with javelins, shields, and heavy short swords. In addition, new Roman Empire specific scenes will be included with the update, such as the Black Forest, the Oasis in Carthage, and more.
The update is live as of today. To find out more about it, head over to the Oasis Games site.
