I hope there is an AI controlled Allied Sub or two in SHV.
So long as the Devs dont script submerged ones lurking in the Bay of Biscay- that would just be evil.

imagine returning to base from your prize 100k patrol...when - BOOM BOOM BABY!!
I hope that the watch crew can spot perricopes and Torpedo wakes - then it will be cool. You have seconds to manover your boat out of harms way (when faced with eels)....
IMHO, that would provide a few minutes of pant sh 1tting awesomeness

And a very nice change from tiresome ol merchents and DDs
And If the prospect hostile AI subs scares you... hear this!
BDU : BE MORE HARDCORE!
