These province capitals have more building slots than the other settlements and are also walled at the start of the game, though in a change from Rome II the small settlements can eventually be upgraded to have walls.
The largest settlement in a province is designated as the province capital. The map of Total War: Attila further extends into modern-day Russia in lieu of the eastern provinces of the Hindu Kush found in Total War: Rome II, shifting the player's attention to the nomadic Huns. The number of cities and regions is different from Total War: Rome II, but the size of the map is similar. Provinces are groupings of three regions, and each region within a province can be conquered separately. The campaign map for Total War: Attila spans from Bactria to Lusitania and from Caledonia to Garamantia in the Sahara.
