Welcome aboard Shrike37

If you want to get the full effect,switch the voices to German and text to your native language,that way you will here alot more speech included, IF you feel the need for more in the way of sound then there are alternatives, There is Thomsen's sound mod,Reece's sound mod,and SailorSteve's 'DasBoot' sound mod.
All of them mentioned are fine additions and offer much more immersion to the sound experience

I'm afraid the link for Reece's Filefront page doesn't contain the sound mod,maybe someone else will have a link that contains it

If I could recommend one other D/L,it would be Torpedo damage final,It makes your strikes and gun hits look so much better than stock
