Secrets

 * 1) In the large room in the center of the map, take the north door, then head west and up the steps. Head south when you can and in this room, use the switch to reveal a teleporter. Take it to be on the western ledge in the large central room. Open the wall ahead of you to find an imp and a teleporter. The teleporter takes you to a soul sphere. (sector 293)
 * 2) In the southeast part of the map, there is a room with cages that contain a megaarmor and a soul sphere. Head south from this room, then east, then press on the gray wall to the north to get a box of rockets, as well as an energy cell pack on Ultra-Violence or higher. (sector 371)
 * 3) At the blue-floored halls in the northern part of the map, make your way to the south side and take the east door. Use the switch and leave, then head north and west through a hall that is now open. Enter the room at the end and use the switch inside, then go back to the hall and use the switch to the south. Go back in the room and take the east steps, then use the next door. A health bonus is in the northeast corner. Open the wall behind the health bonus to find a teleporter that takes you to a soul sphere. (sector 552)
