The new horde mode in Attila allows certain factions to migrate across the map with a large mobile army instead of settlements. As a horde faction, players can build units and technologies on the move until occupying an enemy settlement. The politics system has also been overhauled with more aspects like family trees and a new balance between dominion and control that depends on actions and family influence. Offices provide character bonuses and influence but higher offices require leveled up skills.
