INSTRUCTIONS:
Defend the Allied territory to hinder a German invasion by hunting down the German U-Boats.
Drop depth charges to destroy the German U-Boats.  Depth charges are unlimited, but they take time to load.  You have the choice of dropping the depth charges from the front or from the back of the destroyer.  Watch out and avoid the attacks of the German U-Boats and the Luftwaffe!  Game difficulty increases as the game progresses.  The navy destroyer can only take 5 hits.
Good luck!
