Great War at Sea and Second World War at Sea have covered naval wars around the world, both those that occured and those that might have but did not. One of the flash points that failed to ignite was at the southern tip of South America, where Chile and Argentina engaged in a heated naval arms race from the early 1900s until the end of the Second World War.

Cone of Fire adds the fleets of South America to the Great War at Sea and Second World War at Sea game systems: Chile, Argentina, Brazil and Peru. Both the fleets built by these nations, and the ships planned or ordered but never received, are included. Ships from Britain and Germany are also present.
