My two most horrible deaths in SHIV were in a typhoon class sub and a glitch wouldn't let fresh air be let in even if I was surfaced and we all died of Carbon dioxide poisoning. The other debatable more horrible death was I was patrolling of the coast of Luzon in a Gato class sub and i saw 5 ships( 3 gunboats and 2 battleships). I fired 3 MK-48 torpedo 2 ships sank. One of the remaining dropped depth charges and caused flooding. I began to unwillingly dive to over 500 feet. I responded to telling the crew to surface, no response then I commanded to blow the ballast and I surfaced

. The ships were 2000 yards behind

. So I dived again. I went to about 500 feet when I knew I had to surface, blow ballast. I had critical flooding so I never surfaced.
Please post your stories of gruesome deaths with pictures if you have them.
