Secrets

 * 1) On your way to the switch that unlocks the area with the yellow key card, you will encounter a passage blocked by two metal bars, behind which you can see some ammo. To open them, first press the aforementioned switch, then turn around, go down the lift, and take a right to return to a previously-visited area, where a closet with two chaingun guys will open to your left. Use the computer console inside that closet to lower it like a lift, and you will find another switch there that opens the bars to the secret area. Beware that as soon as you enter the area behind the bars, an arch-vile will spawn. To register the secret, go through the door there, and you will find yourself on the balcony where a mancubus was standing earlier. Besides the ammo, the secret cache includes two backpacks, two medikits, and a megaarmor. (sector 7046)
 * 2) When you press the skull switch in a blue-floored room located in the southwestern part of the map, you will lower the bars that were blocking the entrance to this area. Backtrack past that entrance, then immediately turn right, and then take the next right to end up on a ledge with a berserk pack overlooking a room that you may have previously visited. Drop down to that room, which will reveal a passage to your right with a lost soul in there (pressing the switch in front of you is optional). Go inside that newly-revealed passage, where you'll find another switch. Press that switch and quickly return to the previous room, where a lift has temporarily lowered. Take it up, and you'll find yourself back in the blue-floored room, where you should turn left and quickly run through an open door to the left of the skull switch before it closes. Inside, you can find a BFG9000. Approaching it will also reveal a single zombieman. (sector 11492)
 * 3) At some point, you will see a room in front of you with two chaingun guys and a soulsphere, which you cannot access just yet. To get there, turn right to find yourself in a corridor with several locked doors and a switch. Pressing the switch will activate a trap, closing the door behind you, starting several crushers, and revealing a teleporter that will continuously spawn lost souls, so don't bother trying to kill them all. To clear the trap, first look for a newly-revealed opening leading to a river of blood. Follow it to end up in a room with a berserk pack and another switch. Pressing it will open the door back to the corridor, as well as another door with some demons behind it and yet another switch. Note that when you return to the corridor, another demon will spawn behind you. Press the next switch to reveal the final room with more demons, but beware that some parts of the corridor's floor will now periodically turn into damaging floors, though unlike the crushers, they won't kill you immediately when you stand on them. The final room will lead you to the soulsphere that you've seen earlier - approaching it will trigger the secret. There is also a switch here that will unlock the initial entrance to the corridor, though it will be blocked again when you return there, and you must battle an arch-vile guarding the final switch that allows you to leave. (sector 13403)
 * 4) In the southwestern part of the map, when you press a certain switch, the wall in front of you will lower, leading back to a previously-visited area. In there, a closet to your right with four imps will also have opened. Go inside that closet and use the computer console on your left side to find a secret room with invisibility. (sector 14246)
 * 5) Once you've entered the area behind the door that requires the yellow key card, you will eventually reveal a teleporter that will take you back to a previously-visited area in the northwestern part of the map. A dark closet with five revenants will have opened in there. Go inside that closet and use the computer console on your right side to get a soul sphere. (sector 17461)
 * 6) In the room where the red skull key is, use the wall with a pentagram on it. This will reveal a secret lever in the previous room. Using it will unlock a secret area in the corridor to the south of the room where you found the blue key card earlier. Go in there to find a Doomguy doll, an easter egg referencing Doom (2016) which serves no functional purpose. (sector 19379)
