This is (an early version of) a ShipStyle mod for GalCiv 3 - that is, it adds a new custom set of ships and templates which you can use in place of any of the standard races. It currently features 20 ship models that will take you from Tiny exploration ships all the way through to Huge warships. These template ships can be used with or without the StyleSet modification.
These template files go directly in your Galactic Civilizations III\Designs folder
