During, and before, WWII,
there was no such thing as 'The Cleaner Air Act' add nausium.
Therefore, all rain was Acid Rain by todays standards.
SH3 was modeled with this 'Acid Rain' to maintain Historical accuracy.
Actually, there are no zones assigned to harbors.
No zones means they are Ghost like.
Aircraft can also shoot you while in a bunker.
So the question remaines.
WTF good are the Bunkers?
:rotfl:
