I havent seen any other maps doing this...
I'm also going to have a rotating bookcase (without a hinge so it will just turn on its axis) to go into a secret room.
The purpose of the hidden places is basically an ammo store, and in the attic's case, a way to the roof as well, which leads to a few good sniping locations and a telephone wire leading to the roof of another building, etc.
Hidden doors are fun!
By the way, does anyone know of a way such that a person could walk right through a wall?
