Torpedo Alley

Take your submarine to se nd sink the convoy of ships. The smaller the vessel, the larger your score tally. Beware. The convoy is protected by an escort or anti-submarine aircraft who once in sight will seal your fate and send you to the sea-bed for good! To avoid the watery end, dive as soon as you hear the aircraft approaching, and wait below the surface until you think it is safe to return. Good luck Commander!
