Walkthrough

 * Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

 * 1) In the northwest room, run into the southern light at the west side of the room to lower the north, south, and east elevators. Take the southern elevator to find a secret room with two boxes of shells, a super shotgun (only on Hurt Me Plenty or higher,) one set of shells, two medikits, and a chainsaw. (sector 89)
 * 2) In the northwest room, run into the eastern light at the south side of the room to lower the northwest and southeast elevators. Take the northwest elevator to find a medikit and two stairways back into the room. (sector 221)
 * 3) Upon crossing into the third light from the west in the first long hallway, you will be lowered to a room containing two medikits, a box of shells, a box of rockets, and a box of ammo. This easy-to-access room is marked as a secret. (sector 165)
 * 4) At the fourth light from the west in the first long hallway, press on the lantern to open a compartment containing a box of shells (only on Ultra-Violence or higher) and a backpack. (sector 137)
 * 5) After leaving the first long hallway, run to the corner of the wide, eastern hallway; you will be lowered into a large room with 11 health bonuses and a security armor. (sector 147) There is also a switch at the northwest of this room that will raise a staircase in the passageway into the water. However, doing this will prevent you from obtaining secret #9.
 * 6) After lowering the elevator to access the room with the rising staircase, stay on the elevator until it rises; you will find a roughly L-shaped passage with a chaingunner and a switch. (sector 195) Flip the switch to reveal a teleporter leading to a secret room with two medikits, a stimpack, a backpack, and a stockpile of munitions, including four bulk cells, a box of shells, a box of ammo, two boxes of rockets, a rocket launcher, and a plasma rifle.
 * 7) On the walkway in the room bearing the Icon of Sin's face, a portion of the wall has a collection of candles in front of it. Open this wall to reveal one (two in mutliplayer) bulk cell(s), two (four in multiplayer) medikits, a security armor, and a teleporter back into the lava cavern. (sector 407)
 * 8) In the passageway into the water, there is one wall that is misaligned. Open this wall to reveal a teleporter back into the room you came from, as well as a box of ammo, a backpack and a security armor. (sector 196)
 * 9) The door that opens at the bottom of the stairway into the water is marked as a secret. (sector 175) However, if you raise the stairway with the switch in secret #5, this secret will never register due to being too narrow for you to walk on without climbing up a step in the process.
 * 10) The compartment from which enemies are released in the final, southwest hallway counts as a secret. This actually consists of two sectors, including the door sector, both marked as secret. (sector 167)
 * 11) See secret #10. (sector 168)

Routes and tricks
For years, it was considered impossible to obtain 100% Secrets on this level due to secret #9 being impossible to register, with 90% believed to be the maximum percentage possible. However, in his April 14, 2000 review of Memento Mori, Andy Olivera stated in his description of this level that "contrary to popular belief, you can get 100% Secrets." Eventually, on March 14, 2002, Anthony Soto utilized information from both Olivera and Adam Hegyi to perform his record-holding UV max run of this level, in which 100% Secrets is finally obtained in a demo recording. As indicated above, to obtain secret #9, you must not trigger the stair-raising switch in secret #5, or the secret will not register due to being too narrow for you to step on without climbing up one of the stair steps.
