MAP24: Io Lab (Memento Mori II)

MAP24: Io Lab is the twenty-fourth level of Memento Mori II. It was designed by Sean Birkel in a techbase style reminiscent of Knee-Deep in the Dead, similar to his famous Doom episode replacement, Fava Beans. It uses the music track "GloomKeep" by David "Tolwyn" Shaw.

The level appears to be based on "Shit for DOOM" (SHIT.WAD,) an incomplete Doom level that Birkel had submitted to the idgames archive when he lost mapping inspiration. The original was a replacement for E1M7: Computer Station, and was influenced by that level.

Mission briefing
According to both the text file and the Infopack:


 * This region was one of the first human on Io. The technics [sic] are old and of no use, but the enemy might be interested in it. We don't expect any humans in there, since these buildings were closed months ago. The thing is, when you're back we don't want to have ANY creature out there anymore. So, get going. Nice and easy, you've got plenty of time for this.

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 northern room with two barrels under skylights, the silver pillar in the southwest corner can be lowered to reveal a switch.  Flip it, and then return to the staircase opposite the blue key door to find that a tunnel has opened to reveal an armor bonus. (sector 115) At the end of this tunnel, press on the metal wall to lower it, and obtain a blur artifact.
 * 2) Immediately after the red key door, a portion of the northern wall has taller panels than the rest.  Open it to reveal a secret stairway leading to an alcove east of the containment area, allowing you to jump onto the crates. (sector 142)
 * 3) Enter secret #2, and then jump to the tall stack of crates over which a twitching corpse hangs.  After this, jump to the westernmost stack to obtain a plasma rifle. (sector 190)
 * 4) To the west of secret #3 is a recess in the wall. Open it to find a computer map. (sector 198)
 * 5) At the northwest of the toxic pools, there is a tunnel that ends with a switch.  Flip this switch, and then return to the southwest of the map, in the hallway leading to where you found the yellow keycard.  There, you will find a green portion of the wall, standing out from the brown walls around it.  Open it to reveal a secret tunnel; if you flipped the aforementioned switch, you will be able to head outside, where you can find a medikit, seven clips, a set of shells, a box of shells, a bulk cell, two boxes of rockets, a rocket launcher, and a soul sphere. (sector 32)
