OK, so then we have...
- The siren/klaxxons after torpedo impacts,
- The chaos of yelling, running, tripping, pushing, and running out of the bathroom with your pants around your legs following the "crash dive" order,
- The dive sequence following a "dive to periscope depth" order.
Did I miss anything?
It'd be damned nice if someone added a "screaming injured sailor"-sound file to whenever someone got injured. And some sort of panic or something when the sub was seriously hit. It's just about all that's left to expand (I guess maybe there could be a "Reload!"-order after firing deck guns, too?)
