This is vintage game of abstract naval strategy. Four warships are attempting to destroy an enemy submarine. The board includes spaces with submarine nets and the warships attempt to force the sub into the entanglements. The sub can fire a torpedo at a warship by maneuvering into special "fire" spaces that permit the U-boat captain to launch. The game can be played by more than two players... each additional player commands an individual warship or a squadron of ships in team play. Includes the board and five metal ship tokens.
