A tower is three-level round or square building made of stone. A tall tower constructed atop a prominent landscape feature such as a hill or bluff may be community. The high tower — much larger than a typical watchtower — lets the community keep an eye on the surrounding countryside for a considerable distance, giving it greater advance warning of anyone approaching. The tower community has increased defense, thanks both to its commanding view and the superior elevation over attacking forces that the tower provides the community’s defenders.
In Real time strategy games, it is a defensive unit. It is seen in one form or another in Warcraft I, II, and III. Using it offensively in when playing against another person online is called Offensive Towering.
