I can't wait for the enemy attack subs and improved sonar that will definitely make things more interesting. Also I notice a relatively small bug the occurs when you refit the submarine while having empty torpedo tubes, torpedoes will appear in the empty tubes but they are not considered loaded, however if you order the offending tubes to be loaded crew men will run to the tubes and "load them" after a sec or two and then they are considered loaded. Anyway that's the only bug I noticed so far while playing, while its far from a big deal i just figured I would mention it. Anyway keep up the good work on my favorite up and coming sub sim.
