Went out on my first patrol. Found a convoi ca. 350km west of Vigo. Nighttime, rough weather, missed a liberty at long range, sank a t3 tanker at medium range, crash dived to 175m (escorts already had my number), got depth charged for a few min, then they lost me again. AI seems to work like it should, physics are very nice and make you even more of a sitting duck, which is great IMO. Graphics are fine. Crash dive sound still seems to be played twice in an overlapping manner. Will continue the patrol later on, lets see what happens next.
Edit: The tanker immediately split in half on the first hit. While this happenend the rest of the convoi kept their course and speed (they were at 5kn anyway) and they started zig zag stuff only after the escorts found me. Is that normal behaviour?
