Using new weapons of war, including Dragons, Battleships, Elven Archers, Zepplins, Death Knights and Juggernauts, both Humans and Orcs must use combined-arms tactics in an effort to become the true rulers of Azeroth. The game also includes a new strategic fog of war feature which allows players to only see activity within their units line of sight. Players are not able to see their enemy s movement outside the fog of war, but they can see the terrain of explored areas. This adds a whole new level of strategy as scouting and sentries become vital to defending your territory.
