Hey fellas, just got SH4 and its my first subsim so naturally I would have a couple of quick questions.
Does radar work? if so, how?

Can I go deeper than what the gauge on the interface allows? (without sinking of course :P)
Whats the difference between torpedo types?
and last of all - around what time will I be able to upgrade my sub? (or get a new one)
The rest of my queries Im sure will be answered by practice.
Thanks - see you round on the forums.
