Microsoft has officially announced the existence of Age of Empires: World Domination for mobile devices. There are few details about the game, and it is unknown how the classic real-time strategy gameplay will be adapted for a touch interface, although the preview video promises a new battle system.
This new Age of Empires will feature four factions, the Celts, Franks, Huns, and Vikings; but with no details about gameplay there is little to guess about them. At best, cavalry and siege weapons have managed to make the transition to mobile.
Age of Empires: World Domination is due in summer 2014, and will be available for Android, iOS, and Windows Phone.
