Secrets

 * 1) In the puzzle-like area at the northeast part of the map, the eastern computer room has a red door. Once you get the red key from Secret #4, head back here to open the door to a hellish room containing an arch-vile and a switch. (sector 452)
 * 2) In the brown hallway with metal structs, which is in the southern part of the map, use the switch near the south door to open it. Walk onto the computer terminal in this small room using the light on the floor and press the red panel, which allows you to get the plasma gun and energy cells in the room. (sector 1266)
 * 3) From the door leading to Secret #2, take the other door to another brown-floored hallway and take a left. In the lounge area with the zombiemen inside, press on the red, vent-like panel to lower it into a small corridor with health bonuses. (sector 1262)
 * 4) Inside of Secret #3, one of the pickups is actually an armor bonus. If you pick it up, look closely at the floor and you will see a small area pointing east. Press on the wall it points to to get the red skull key. (sector 1250)
 * 5) The switch that is pressed in Secret #1 raises a walkway on the western side of the puzzle room. Make your way there and open the vent shaft to drop in. From where you drop, go right, moving northwest through the shaft until you reach a fork where a lost soul attacks from the left and another fork is to the right. From where the lost soul was, open the shaft to a small room with monsters, medikits, a BFG9000, an energy cell pack, and a switch. (sector 413)
 * 6) At the fork mentioned in Secret #5, go right, and then right again (there is another lost soul in this fork, but only on Ultra-Violence or higher). The vent should dump into a small room with imps, medikits, and a megaarmor. (sector 365)
 * 7) Press the switch in Secret #5, then head back to the starting room. Open the door that leads to the yard outside, then open the door in the depression on your right. (sector 481) If you had not pressed the switch in Secret #5, you will not be able to open the door.
 * 8) Inside Secret #7, shoot both of the black marble faces to open the bars that lead to the secret exit, going to MAP31: Mortar Combat. (sector 1197)
