"By Stealth and Sea" is a tactical solitaire or cooperative wargame 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 special forces assault units 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?

Object of the Game

You score points based on the type of naval vessels and support ships you sink. Points scored during a mission can be used to advance your technology and train your operators for future missions. Your goal for the campaign is to meet or exceed the historical accomplishments of the manned torpedo operators of the Decima Flottiglia MAS.

Gameplay

By Stealth and Sea is divided into turns. Each turn consists of the following phases:

Fault Check Phase: Check to see if there is a fault.
Manned Torpedo Phase: Each manned torpedo uses two action points.
