I created a rather big and, I would say, sophisticated map so that
players, while tracking enemy, could wander a bit in the ATC building.
I spent much time for choosing lights. To see all dark places I
advise you to play in full darkness.
At the screenshots you can see basic map locations, but there
are still some not shown places and game features which you will find, I think,
rather interesting and, perhaps, even impressive. :)
