Had to take a break... I just attacked this massive convoy in broad daylight. It was harrowing, and escape was not a sinch.
I swear to god, the ships in GWX lol... they take hits for fun! I put three torpedoes into a LArge Cargo, wouldn't go down, but was crippled.
I put I think, 4 into a medium tanker and that was only crippled, I had to lose the Black Swan first, before I could surface and finish them off with my deck gun, I only have 3 paltry torpedoes left now!
