MAP01: Secret Operation 1 (Memento Mori II)

MAP01: Secret Operation 1 is one of the two top-secret bonus levels of Memento Mori II. It was designed by Steve Towle and uses the music track "Avalanche" by Mark Klem. It contains a separate area for multiplayer competition.

This map and MAP02: Secret Operation 2 are not included in the regular PWAD. To play them, you must download the Memento Mori II infopack, rename the file MM2INFO.DAT to MM2INFO.WAD, and load it alongside MM2.WAD (and, optionally, MM2MUS.WAD.) Some modern source ports can load the .DAT as a .WAD without any renaming needed. This map replaces MAP01: Outpost.

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.

Essentials
Upon starting the level, kill or evade the enemy standing in front of you (a trooper on Hurt Me Plenty or lower, an imp on Ultra-Violence or higher.) You can evade or kill the sergeants and grab the shotgun under the hanging corpse. Head up to the switches; the western switch activates the elevator while the eastern switch opens the door. Activate them both, and circumvent or dispose of the demon (Hey, Not Too Rough or lower) or spectre (Hurt Me Plenty or higher) in your way. When the elevator has raised, open the door and rush out, or kill the spectre (Ultra-Violence or higher) in the next room. Enter the house at the north of the map, and head through either door into the central room; dispose of the enemies there. Head up either staircase and enter the hallway, lined with health bonuses. Grab the red skull key (Hey, Not Too Rough or lower,) or activate the center switch to lower a pillar in the central room holding a red keycard (Hurt Me Plenty or higher.) Leave the house, open the red key-locked bars on the east, and rush through the opening to finish the level.

Secrets

 * 1) In the room after the elevator is a misaligned wall. Pressing on it will reveal a hidden teleporter; using it will take you into a secret compartment behind the starting area with security armor, a sergeant (only on Hurt Me Plenty,) and a chaingunner (only on Ultra-Violence or higher.) (sector 2)
 * 2) Upon entering the house, press on the demonic face to find a secret compartment containing a box of shells. (sector 189)
 * 3) In the room full of switches, press the third switch from the east. (All other switches will shut off access to themselves and each other.)  Head back to the starting area to find a secret compartment containing two medikits, combat armor, a chaingun (only on Hurt Me Plenty or lower,) and a chainsaw. This counts as six secrets. (sector 26)
 * 4) See secret #3. (sector 27)
 * 5) See secret #3. (sector 28)
 * 6) See secret #3. (sector 29)
 * 7) See secret #3. (sector 30)
 * 8) See secret #3. (sector 31)

Bugs
It is only possible to obtain 78% Kills on this level due to non-functioning monster teleporters that leave seven enemies outside of the valid playing space.

Also, in multiplayer, there are several clips in the walkway surrounding the house, clips and shells in the elevator, and shells in secret #2, in spite of the single-player area being inaccessible from the multiplayer one.
