Forbidden Rooms (mfrbroom.map)
Author:  Martin Brentnall
Type:    BloodBath (3-6, Trap Arena)
Details: A natural follow and much larger follow to Quartet, this map has
         large corridors and large rooms styled in a clean look.  Most traps
         are activated from one location utilising one-way walls to spy on
         your victims.
Secrets: Go to the room directly ahead when you reach the top of the large
         slope.  You must wait for someone to activate the trap in this room,
         which opens the door at the back releasing some monsters.  Run
         through this door whilst it is open.  A passage from here leads into
         the secret, in which you can activate some rockets.
         Note that you can only stay inside the secret for a limited time,
         otherwise you will be crushed by the descending ceiling.
