A rare Windows-native version of the Sierra classic. Released in 1995. From the back of the box: "Take command in the most realistic and technically advanced WWII German U-Boat simulation ever created. Exploit your tactical strengths and stalk the waves of the North Atlantic in a battle where the hunter quickly becomes the hunted. Attempt to strangulate shipping lanes and outmanoeuvre convoy escorts. React as technological advances - such as sonar and radar - mean guile and cunning are more crucial than ever. Use your skill and judgement to ensure that you and the crew of your boat survive to fight another day."
