Ive found GW very interesting as far as weapons are concerned, nothing is a dead sert. My last mission i came across my first convoy, i was so gob smacked and was sight seeing i didn't see the escort untill the shells were explodeing around the conning tower, and like a heat seaking missile the git blew me out of the water.
Apon re-birth (thankfully id saved before he attacked) i knew what to expect, and when he was still some distance away i used the deck gun, firing with more hope of causing damage i fired my first round, and was amazed when the whole boat leaped out of the water and broke in two, Now either this was HMS Hood or one hell of a luky shot, any other time i can lay a torp and 50+ shell into a freighter only to have it sail away into the distance.....it is the uncertanty that makes the game enjoyable and yet sometimes very frustrating.
