MAP22: The Escape (Memento Mori)

MAP22: The Escape is the twenty-second level of Memento Mori. It was designed by Denis Möller and uses the music track "Triangle of Fear" by Mark Klem. It features a similar situation to the Spider Mastermind / Cyberdemon duel from Doom II's MAP20: Gotcha!, where the player must trick two Spider Masterminds into fighting each other.

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) After the two Spider Masterminds are dead, run onto the switch platform, and open the western wall with bloodstains on it to find a berserk pack. (sector 131)
 * 2) After the two Spider Masterminds are dead, run onto the red skull key platform, and open the wall with bloodstains on it.  Take the elevator down, and then lower the next elevator to acquire a security armor. (sector 324)
 * 3) Walk onto the bridge to the yellow skull key from the south.  A chunk of the wall will raise in the walkway.  When walking across the space it was on, you will be lowered an elevator to a compartment containing a group of imps, two sets of shells, and a stimpack.  Run across the northeast corner of this space, flip the newly-revealed switch, and drop in.  Enter the additional elevator that has been lowered, ride it, and open the metal door to enter a cage containing a soul sphere. (sector 260)
 * 4) In the teleporter room, shoot the monitors to open a compartment containing three sets of shells, a stimpack, and an arachnotron.  Kill the arachnotron, and then open the wall with the triangle upon it to find a hidden corridor containing a megasphere. (sector 461) Go further down the corridor to reenter the sewage area.

Routes and tricks
If you edge very slowly toward it, you can grab the yellow skull key without triggering the chaingunner trap behind you.
