i havent had SH4 for very long, only been killed twice. once i was waiting for a small convoy to come to me. i was ahead of them in firing position all stop and silent at night. i poke a scope up to have a peek as they were getting closer and saw no sign of suspicion. so i upped the time compression a tad. next thing i know the escort closest to me drives over my tower in a depth charge run.
the other wasnt much of a death... i escaped 4 destroyers with a destroyed rudder. that made me mad more than anything else thats happened.
