Map of MAP28

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


  1. After leaving the map start area, standing in front of four steel walls, strictly go west. In the southwesternmost region of the map, east of the two dead trees, go south, but do not push the switch (it raises a stairway). Instead, run to the inset in the eastern wall, thus opening an alcove in the north of the dead trees, releasing a hell knight on easy, a baron of hell on medium or an arch-vile on hard skill levels and a pain elemental. Open the inset to reveal a lift. Take it up into the baron's pillbox, containing (a BFG9000 on easy and medium skills,) a box of shotgun shells, a box of rockets, a bulk cell and a backpack. Entering this pillbox opens an alcove in its southeast, releasing a sergeant, two (one on easy skills) chaingunners, (an arch-vile on hard skills,) (a revenant on medium and hard skills,) and a baron of hell. (Raising the stairs after opening this alcove will not prevent you from registering the secret.) Enter this alcove to find (another deaf baron on medium and hard skills in front of) an elevator (sector 223) (with an arch-vile on it on medium and hard) that you can take up to the pillbox and back again. Going through the bloodstained door in the northeast of the map will open the wall hiding this elevator in the pillbox if you have not opened it from the elevator before.
  2. From the four steel walls mentioned in secret #1, strictly go north, passing the super shotgun's plinth and the lit circle with the three medikits. Push the switch west of the mancubus's platform to lower it, revealing the entrance to a room with two sergeants, (a baron on medium and hard skills,) a bulk cell and a teleporter. Open the northwestern wall (sector 508) in this room to find a backpack and another bulk cell.
  3. From the switch you used in secret #2, continue going north, passing a wooden guard tower (sector 233). Enter the building in its north from the western side and jump from the southern window into the guard tower to acquire a box of bullets, a backpack and a bulk cell.
  4. In the central building (to the west of the mancubus's platform mentioned in secret #2), cross the southwestern corner to the east, and a wall will open in the northwest of the building. Go back to the northwest to find (a chaingunner on hard and) a backpack (sector 149).
  5. Triggering secret #4 to open also opened a compartment right east of that corner, containing a spectre, (a hell knight on hard,) a shell box and a rocket box. Open the eastern wall (sector 153) to find a soul sphere.
  6. In that same compartment, open the western wall (sector 155) to find a bulk cell.
  7. In the northeast of the central building, flip the switch, and then return to the west to find that the silver bars blocking another switch have been raised. Flip the switch, and then enter secret #4 to find another compartment (sector 456) containing a blue armor.
  8. In the northwestern room of the easternmost building (east of the one with the mancubus's platform mentioned in secret #2), press on western portion of the southern wall to reveal a corridor (sector 524) containing three energy cells. It also leads into another room containing (a chaingunner on medium and hard and) a bullet box.
  9. In the northern room of the easternmost building, enter the room to the east and exit it through the southern door. After that, exit the building and head over to the eastern side to find a newly-opened compartment (sector 200) containing three sergeants and a bulk cell.
  10. After jumping the gap into the gray stone building in the north of the one where you found secrets #8 and #9, open the second northern wall (sector 296) after you enter to reveal a backpack, a shell box, a berserk pack and a blue armor.
  11. In the cuboid outdoor area (in the northernmost part of the map) with the switch opening the door to the toxic pool, the southernmost portion of the western wall in the southwest looks different from the others. Open it to reveal a secret room (sector 408) containing a backpack, eight bullet boxes, five shell boxes, three boxes of rockets and a megasphere.
    Since you can open this room only once, you should save it up until right before entering the yellow door as from the area behind it there is no way back to the rest of the map.
  12. In the same cuboid outdoor area, the northernmost portion of the western wall has a different texture. Open this wall (sector 425) to find a computer map.
  13. Hit the switch in the east of the toxic pool room to reveal a switch nearby the entryway. Use it, then enter the walkway surrounding the pool and head to the southwest. A wall will have opened here revealing a compartment (sector 491) containing a soul sphere.

Routes and tricks

This level is notorious as the hardest level in Memento Mori to speedrun, due to its impressive difficulty provided by not only the powerful hellspawn, but also impressive complexity that allows for little to no shortcuts. A UV speed run through this level takes close to 8 minutes to finish, and a UV max run requires more than 15 minutes; the slowest UV max demo ([1],) by Istvan Pataki, lasts a showstopping 24:01.

One shortcut is a key grab that can be performed with the red skull key, by straferunning against the northern side of the platform the key is on. However, circumventing the process of lowering the platform also skips the opportunity to grab the plasma rifle, which is a necessity against the powerful enemies that inhabit this level, meaning it is not wise to perform in a single-level run. The only demos in which this is used are Drew "stx-Vile" DeVore's 31:11 MAP21-30 UV Episode run ([2]) and his 83:56 UV Run of the entire megawad ([3].)
