Corrected the "Emergency Access" map from Medical Center in BS1 :


The original map made no sense when compared to the Austen Bathysphere Map not even as a symbolic map.
Map is 'non-civilian' paths used by security personel to many significant locations in Rapture.

Something like this would be used as part of a 'security' mini-game/quest/mission (the Constables are New Rapture's "first line of defense" against the chaos beyond the border.)
