Secrets

 * 1) At the far northeast end of the map with the bridge past the rocky halls, take the door, which will actually lower, and stand on it. When the door rises, jump northeast into the lava below, then go east to find a megasphere and a teleporter back. (sector 604)
 * 2) From the cross-carpeted hallway at the northeast part of the map, go north and around to an area with supplies. At the end room where the arch-vile is, press the wall to the south to get another megasphere. (sector 757)
 * 3) In the same area as Secret #2, lower the wall to the east to reach the platform with the baron(s) of Hell, where you can get a berserk pack and boxes of rockets. (sector 2158)
 * 4) At the library in the northeast end of the map, head for the northwest part of the area with the square rooms, then find the southwesternmost room. Lower the wall with a pool of blood in front of it to find a teleporter to a secret area. Here, collect the computer area map behind you, as well as a backpack, a box of shotgun shells, and energy cells ahead. You can also jump to the bookshelf containing a megasphere. (sector 1225)
 * 5) At the field with the sun-like structure on the ceiling, which is directly south of the northeast part of the map, climb up the steps a bit and go north onto the ledge with armor bonuses. Go to the alcove with medikits and a green armor, then look east to spot a tucked-away switch. Shoot it, then head south onto the other ledge with armor bonuses, going south into the secret room, containing a lost soul above a shotgun guy's corpse along with boxes of rockets and energy cell packs. (sector 918)
 * 6) In the small room with the pentagram containing a megaarmor, a berserk pack, partial invisibility, and a soul sphere, press the switch at the back to lower columns containing imps. Enter the northwest alcove and open the wall to find an invulnerability. (sector 1034)
 * 7) At the westernmost room, raise the steps to the north and south, then take the south steps up. Press the skull switch to the east to lower the bars nearby, but instead of going past them, stay on them and ride them up. There are passages up here with energy cell packs and an invulnerability, and there is a teleporter that will allow you to telefrag the cyberdemons outside, netting you a megasphere at the end. (sector 1398)
 * 8) Go past the bars mentioned in Secret #7, looking at the faces in the hall. One of them is a gargoyle face instead of a satyr face, so press it to find a hidden room with medikits, energy cell packs, and a megaarmor. (sector 1417)
 * 9) Once you open the way past the north stairs on the west side of the map, take them up and you will find a room identical to the one you found at the top of the south set of steps. Again, press the skull switch and ride on the bars, then turn left and into the secret room with the energy cell pack and megasphere. (sector 1680)
 * 10) In Secret #9, press on a section of wall to the north to reveal a skull switch, which will reveal a new passage across the bars. Go there to find an invulnerability and more energy cell packs, as well as a teleporter to the northwesternmost room, telefragging a spider mastermind in the process. (sector 1681)
 * 11) In the final area, press both skull switches to reach the exit room, then enter it, but do not enter the exit. Once you enter the exit room, return back to the arena and go around the southeast column to find a teleporter. (sector 2103)
 * 12) The teleporter in the previous secret takes you back at the top of the north steps at the west side of the map. Enter the room to the west which is now open to find a switch. (sector 1613)
 * 13) The switch in Secret #12 opens up a similar room which is at the top of the south steps. Head over there to get a megasphere. (sector 1578)
 * 14) Attempt to exit Secret #13 and you will teleport back to the starting point. The door here will be open, and the dark passage leads to the secret exit of the map. (sector 2156)
