Official

 * 1) In the second room you come to, flip the switch to lower a lift to a chainsaw. Ride it up, and look east to find a switch. Shoot it and then flip the other switch to lower yourself back down. One of the columns here has lowered so you can get a backpack. (sector 875)
 * 2) In the same room, if you approach the imps, a wall with arachnotrons is revealed behind you. Look at the green walls here and notice that one of the walls has gray lights instead of blue lights. Press it to reveal a corridor. (sector 52)
 * 3) In the hall where an invisible ledge with revenants is lowered, ride up the small platform in the northeast of the hall, set into the raised north side of the room. Go through the door on the left, outside, and then inside the small corridor. When you reach the door, open the wall to the left of the door for a passage going back. (sector 3105)
 * 4) Open the wall to the right of that same door for a teleporter. (sector 3109)
 * 5) Take this teleporter, but do not step off of it. Instead, open the wall behind you for a megaarmor. (sector 1083)
 * 6) At the eastern hall, take the stairs south and open the next door. Look to the right for an X on the wall. Shoot it, then descend the stairs and you will find an opening in the north side of the central pillar. Get onto the ledge surrounding the central pillar and move to the opening before it closes to get a megasphere and two boxes of rockets. (sector 2561)
 * 7) South of the hall with red and blue insets in the floor is a large room where you can collect a plasma gun and a chaingun. Go around and behind the chaingun's platform and head directly behind it to be lowered to a box of shotgun shells. (sector 238)
 * 8) To get this secret, head onto the chaingun's platform to hear a door opening. Go back to Secret #7 to find another opening where you can get another soul sphere. (sector 1227)
 * 9) On the bridge leading to the red key building, if you look to the southwest, you will see a small dark patch of wall to the right of the furthest pair of gas lights. A switch is behind this wall. Shoot it, head to the red key building and go around to the other side to get two boxes of shotgun shells. (sector 3404)
 * 10) When you grab the blue key, you also open up a closet with revenants inside; this closet is at the top of the stairs in the hallway that is south of the blue key. Enter this closet and use the brown-wired wall to lower it for a passage. (sector 1580)
 * 11) After grabbing the red key, several traps open in the previous areas. As you backtrack to the red door, you will find a trap in the southeast of the hall with red and blue insets in the floor with mancubi in it. Inside this niche, press on one of the gray walls to the right of the computer terminal to reveal a room of revenants, boxes of rockets, and ammo boxes. (sector 610) Inside this room, if you press the switch, a window appears in the south of the room. Press it again to reveal a conveyor belt with bodies and an armor. Press the switch one more time to "deliver" the armor to an alcove in the east of the room, where you can pick it up.
 * 12) In the yellow keycard room, press on the wall that says UAC to lower it, then ride it as a lift. At the top, shoot the skull switch to reveal another switch in the room. Flip this switch, which lowers the western windowsill so you can drop into the pool. The railing on the western part of this area has also lowered, step on it and rise up to get a medikit and some supplies. (sector 547)
 * 13) This secret is best collected together with secret #12. Flip the hidden switch in the yellow key room that lowers the western windowsill and railing to get to Secret #12. Drop into the water, then press the unlowered half of the windowsill from the water (it will lower). Head onto the railing to get to Secret #12, then run all the way east and you should get a megaarmor before it rises. (sector 652)
 * 14) Near Secret #13, in the same general area accessible from Secret #12, there is a portion of the rocky wall that is misaligned (it can also be spotted on the automap as the only part of the northern wall running perfectly east-west). Press on it to lower it, claiming a berserk pack. (sector 3342)
 * 15) Once you grab the yellow key, leave the area and come back to some mancubi attacking you. The gray-walled closet that they were in has a metal wall. Press on it, then run into Secret #2. An alcove near the entrance to the secret will have temporarily lowered, with a soul sphere. (sector 973)
 * 16) After getting the yellow key, head back to the hall where the invisible ledge of revenants was (this area probably has more revenants in it by now) and take the lift up again. Follow it to where Secrets #3 and #4 would be and, if you have not already done so, open the door and flip the leftmost switch. This opens up a corridor just before the door. Take this corridor, up a lift and onto a gray ledge with lights, going around the gap to the other gray ledge with lights. Now drop onto the gray ledge that does not have lights and head into the green-floored area. Another room will open and revenants will be lowered from columns. If you look to your left in that area, you will spot an opening you cannot reach as well as an indentation on the right wall. Press this indentation to lower the wall behind you. Now, in order to access the opening, you will have to retrace your steps a bit. The quickest way to do so is to drop into the big hallway nearby and lower the wall in the revenant closet (this closet opens when you are heading for the yellow key after picking up the red key). There will be an arachnotron when you lower the wall, but you want to ride it back up. After doing so, go back to the wall you lowered via the indentation on the wall, and you should access the opening. Head inside and flip the switch to raise the columns the two revenants were on. Now use one of them to rise up and then hop into the corridor with health and armor bonuses. (sector 668)
 * 17) Open the yellow door near the exit of the level. When you approach the middle of the bridge with the rocket boxes and stimpacks, the ends will lower and you will be stuck in the middle against several Hell knights for a while. When the ends of the bridge rise back up, you can head to the exit, but before you do so, head back through the door you came in from. There will be a new opening on the left side, leading into the teleporter that was accessible from Secret #4. Go through this teleporter, and there will be another open passage in front of you, leading back to the two switches and the imp cage. Flip the rightmost switch, then quickly run back through the teleporter heading close to the yellow door. A ledge with armor bonuses and imps has lowered, and there is an opening you see leading outside. Wait for the ledge to rise and jump through the opening and follow this path to energy cells and a berserk pack. (sector 1369)
 * 18) Near the pickups available from Secret #17, there is an indentation on the wall. Press it to access a soul sphere inside one of the Hell knight closets. (sector 1170)

Non-official
Inside of Secret #16, there is a misalignment on the western wall. If you shoot this misalignment, a door opens up into an easter egg room with an image of a human chest as well as the words "IT'S A CHEST!!!". This area does not count towards the secret total.
