User Summary A clear predecessor to Silent Service, Submarine Commander was the first 1st person submarine simulator available to the general public. The player takes on the role of an German U-Boat commander in WW2 taking on Allied convoys in the Mediterranean. A rather sophisticated sim, the player first tracks down convoys on a navigation screen before going after them at periscope depth with torpedoes. Watch out for destroyers, and make sure you don't run out of air or battery juice for your E-motors.
