Bewolf

To give you a bit more practical help, in german boats you first have to chose which torpedos to fire in a spread. You do that in the attack map. There is this little button next to the tube selector, labelled T/S if memory serves me right. Pressing this will change the tube selector into a tubeS selector. There you chose the tubes you want to use. Once set, you go to the right and check the spread. Once set that as well, you are ready to fire. Do not forget to open the tubes you selected.

Now once you have your firing solution, just press fire and all the selected torps will launch automaticly in a salvoe.
