This particular career (above post) is over. I ran out of fuel then discharged the batteries down to a trickle while running at periscope depth, (they won't discharge completely and you can travel at 1/2 knot but it'll take months or even longer to get back to port even under TC.). I then stayed underwater too long and the C02 killed everybody, hence...
Game Over.
OK, learned something from all that. It's now time to back up a bit and take control from an earlier save.
I'm having fun... are you?
