Secrets

1. At the rocket launcher, jump south into the lava and enter the corridor to get the white skull key. (sector 7791)
2. Head southwest of the blue skull key and open the south wall which is brown to find a soul sphere. (sector 7078)
3. In the central room at the west side, go to the southeast wall which is darker and open it. Take the teleporter to an area with armor bonuses, a backpack, and medikits. (sector 1497)
4. Just south of where you teleport to Secret #3, open the south wall which is darker to find a fiery passage with a megasphere and a hole. (sector 1591)
5. In Secret #3, open the white key door and then open the north wall to get a green armor and a chainsaw. (sector 3610)
6. In the northwest hall of the west side, use a red trident on the north wall to reveal a hole. Fall in to get up and around to elemental wand ammo. (sector 6855)
7. In the lava cavern leading to the red key, after crossing a bridge, lower the south wall which is orange and has a candle in front of it. The passage behind the wall leads to a soul sphere. (sector 6666)
8. Head east of Secret #7 to the switch. Behind it is a berserk pack. (sector 6707)
9. Find three hidden switches around the west side of the map. One switch is at the northwest end of the northernmost area with the green armor. At the east side, there is a switch on a column in the room to the southeast of where the blue key is. The last switch is southwest of the red key, on the north side of the ledge with revenants. After pressing those three switches, head south of Secret #5, drop into the pit, and swim all the way to the other side. When you surface, go west and north to a switch. Press this switch and return to the water which is draining. The door to the west will open to a secret area with a megasphere, a BFG9000, energy cells, and energy cell packs. (sector 3983)
10. On the large bridge, drop into the lava at the southwest end and take the teleporter to get an invulnerability. (sector 2937)
11. On the large bridge, drop into the lava to the north and go north to some platforms. Go to the teleporter and jump east of it to get elemental wand ammo. (sector 3385)
12. In the yellow key chamber, climb the rocks to the west, then jump onto the support beam and head south to get elemental wand ammo. (thing 1148)
13. Head back to the north end of the beam and run east to more rocks. Climb up and follow the dark cave around to the east side. Jump to the megasphere for the secret. (sector 6485)
14. Open the yellow door and press on the beige wall to the southwest to pick up a computer area map. (sector 6393)
