By Stealth and Sea is a solitaire or cooperative game that takes place during the Battle of the Mediterranean in World War II. In By Stealth and Sea, you lead elements of an Italian commando frogmen unit called Decima Flottiglia MAS. Under your command, teams of frogmen will pilot manned torpedoes in attacks against the Royal Navy in the heavily guarded harbors of Gibraltar, Algiers, and Alexandria. By Stealth and Sea’s campaign system features all nine key historic manned torpedo attacks by the Decima Flottiglia MAS against the Royal Navy. During the campaign, you can advance your technology and train your frogmen, but the Royal Navy responds to successful attacks by improving their defenses. The remarkable accomplishments of the Decima Flottiglia MAS served as a model for other naval special forces for years after World War II. Will you be able to match these historic results? Or will you succumb to the defenses of the Royal Navy?
