Make sure your game is up to date (1.02b)
(Should happen automatically on STEAM)
Your base is denoted by a Green Square (Holy Loch I think it is called)
This is the only port you can dock and resupply at
Regarding detection when starting a mission
There is a
really,
really important thing to consider when travelling on the Campaign Map - this is not covered by the tutorials
There are two speeds you can transit the campaign map with
If you left click on the mouse you will be hauling azz at flank speed (I call it transit speed)
If you right click on the mouse you will be travelling at patrol speed
This makes a massive difference to how any encounter with the Soviets will start
If combat starts at transit speed, you will be dropped into the mission at 25 knots, they will already have a good idea that there is something out there, and will probably be banging away with their active sonar.
You are already at a massive disadvantage
If combat starts at patrol speed, you will be dropped into the mission at 10 knots, they probably do not suspect anything, their active sonar will probably not be active (although there is a chance)
Now you have an advantage
If combat starts when you are stationary on the map, you ambush them.
You will be dropped into the mission at 5 knots.
They should not have a clue you are out there.
Massive advantage
Try to anticipate enemy movements and ambush wherever possible - otherwise you are gonna have a hard time
Stick with it cookiemonste
It's an awesome game, and just gets better with experience
Good hunting mate
