Raiders of the Deep: U-boats of the Great War, 1914-18 is a solitaire, tactical level game placing you in command of a German U-boat during WWI (known at the time as The Great War). Your mission is to destroy as much Allied shipping as possible, while advancing your crew quality, increasing your Commander rank, and attempting to survive until the Armistice and the end of the war. Raiders of the Deep is based on the popular Hunters game system by Gregory M. Smith and marks the first dedicated boardgame treatment covering WWI U-Boat warfare.
