Bombard Tower

Bombard Towers are powerful Defensive Structures on Age of Empires II available in the Imperial Age. They are a Gunpowder Unit, so require Chemistry to have been researched from the University beforehand, as well as its own technology. They cost 200 Stone and 75Wood to be built, and can only be built by some civilisations. They can only be outranged by Trebuchets and Bombard Cannons. It is extremely difficult to destroy a Bombard Tower without one of these units.
