Iron Working (Civ1)

Iron Working is an advance in Sid Meier's Civilization.
== Strategy ==
Iron Working allows the building of Legions, a cheap offensive unit.
It is a prerequisite of Bridge Building and Gunpowder.
== Civilopedia entry ==
Building on the experience of their Bronze Working, ancient smelters learned Iron Working, the manufacture and fabrication of a much more useful metal. Iron ore was extremely common compared to copper and tin, and Iron was harder, less brittle, and could hold a much sharper edge. It was an ideal material for tools and weapons. Some observers consider the development of Iron Working to have been a key step in the advance of civilization. It made workers much more efficient and was found useful in many new applications.
