Nice. I saw some game footage and the UI seemd a tad clunky. Is that your experience?Yes, the subs are really fragile. Torpedo launches are simplified. Target enemy > Wait for good solution > Fire # of torps with a degree spread you set.
I have slipped away one time by diving deep early and running silent.
I have yet to trying to go deeper to see how far the subs can truly dive to and see if you can get under the depth charges. Historically, the Japanese set too shallow in early years of the war.
