If you think the fog and rain are a bit heavy (I wanted to convey a tropical storm) then open Mission Editor and alter Precipitation, Rain and Fog to light or nill! If you would like to play the mission as a Single Mission then open in Mission Editor tick the Single Mission box and delete the U-Boats you do not need leaving you with one "Player" U-Boat. KUrtz
Bump In Mission Editor open Mission/Events and in the Message Event box click "Message is Critical". That should fix what is my second attempt at making a mission! KUrtz.
