MAP31: Technology Base (Memento Mori)

MAP31: Technology Base is the first secret map of Memento Mori and can be accessed from MAP15: Karmacoma. It was designed by Denis Möller and uses the music track "Slipper" by Mark Klem.

The level is designed to place Players 1 and 3, and 2 and 4 on separate halves of the level in cooperative multiplayer, with both teams meeting only after a certain wall is lowered at a rendezvous point, rendering half of the level normally inaccessible in single-player gameplay. However, due to a design flaw, the player can enter the "inaccessible" half of the level in single-player, and consequently, Players 1 and 3 can cross over into Players 2 and 4's side early (see Routes and tricks.)

Secrets

 * 1) In the hallways after the room accessed by the yellow keycard, press upon the wall with triangles upon it in the east to reveal a stairway into a hallway behind one of the platforms in the previous room. There, press on the wall at the north to reveal a teleporter, leading to a platform at the beginning of the level with a megasphere.  Walk off the platform to teleport back to the hallway.

The following secrets are on Players 2 and 4's side of the level. Thus, they cannot be accessed by Players 1 and 3 in coop until the rendezvous wall is lowered, and they cannot be accessed in single-player unless one exploits a design flaw (see Bugs).


 * 1) Beside the switch that raises the bridge in the lava passageway is a portion of the wall with faded coloring. Pressing on this wall will allow you to access the chaingunners' cage, containing a medikit, a box of bullets, a bulk cell, a chaingun, and a super shotgun.
 * 2) In the hallway with stairs leading up to the switch that lowers the bars, press on the northern wall the light is shining on to reveal a compartment containing four stimpacks, an armor bonus, three clips, and three sets of shells.

The following is not marked as a secret, and does not count in your Secrets tally at the end of the level:
 * 1) In the lava passageway, there is an inset in the wall that can be opened to reveal a teleporter leading to the second secret level, The Hidden Slime Factory. This is only accessible on Players 2 and 4's side, rendering MAP32 inaccessible in single-player gameplay unless one exploits a design flaw (see Routes and tricks).

Routes and tricks
On top of the raised teleporter platform at the rendezvous point, you can pass through the window provided you turn slightly to the right, and walk off the platform through the opening where it bends on that side. This will allow you to access the part of the level normally inaccessible in single-player gameplay. This can only be attempted once, however, and if unsuccessful, you will be unable to try again until you restart the level (or restore a saved game prior to attempting it,) as you must permanently lower the platform to the ground to get onto it again. In ZDoom and related source ports that allow crouching, you can simply crouch-run off the platform through the window. This is the only way to access the secret exit in this level in single-player (see Secrets).
