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


 * Sector coverage:
 * Laboratories, Grade-A clearance required for assess [sic] to data.


 * Agent report follows:
 * I have gained access to the laboratories and observed some of the monsters at work. I don't know what this place was used for before the invasion, it looks like [portion of text censored] and the creatures seem to be using it for something.


 * At the moment I have reached the first laboratory. It looks to have carved [sic] from a natural underground cavern.  Some of the small spider brains are supervising some zombies who are working on the [portion of text censored] and conducting what look like light-wave experiments.  I thought I recognised one of the zombies, it may be a friend of mine.  I'm going to try and make contact.


 * Later I'm hoping to go deeper into the labs. It sounds like they're testing heavy weapons further in.

Essentials
Take the elevator down, and rush to the northeast door. Enter the central door to find the yellow keycard. From there, what you must do depends on the path you take. If you take the western path, go through the western doors, enter the southwest or northeast teleporters, take care of the opposition, and grab the blue keycard. Head back to the teleporters, enter the northwest door, take the elevator, and tread along the walkway to the northern room. If you take the eastern door, flip the switch in the east side of the machine, enter the teleporter, open the door, kill the monsters in front of you, and grab the blue keycard. Head back to the teleporter room, enter the northeast door, take the elevator, cross the walkway in either path to trigger an elevator, and take that elevator up. Whichever path you take, once you reach the northern room, rush over, and grab both the red keycard and the rocket launcher. Backtrack to the very southern room, and take the silver elevator up into the computer area. With the red and blue keycards in your grasp, activate both of the computer controls to open access to the center of the room. Dash in there to open the exit door to the northwest, and then run into the newly accessible elevator to finish the level.

Other points of interest
In the western teleporter room, on Hurt Me Plenty or higher, there is a former human (a sergeant on Hurt Me Plenty, and a chaingunner on Hurt Me Plenty or higher) inside of the northwest pillar who will shoot at you through the southeast side. To kill them, you must fire into that side yourself. In addition, if you run into that side, you will obtain a medikit.

Secrets

 * 1) After obtaining the yellow keycard, go through the western yellow door and open the metal door with grating upon it to the west. This reveals an elevator up to a secret corridor (sector 147) that leads to a rocket launcher.
 * 2) Return to the hallway north of the western yellow door and proceed northwards. In the western teleport room, enter the southwestern teleporter. After that, walk up to the wall with the skull upon it, and open it to access a hidden corridor (sector 29) with a set of shells and a super shotgun. Note that the super shotgun here may prove difficult to obtain unless you back against the opposite wall, and then bump into the stand it is on as quickly as you can.
 * 3) In the red keycard room, step from the walkway west of the nukage pit to the walkway north of the nukage pit and run as quickly as you can to the northeastern corner of the room, where you will find that an elevator (sector 178) has lowered to reveal a plasma gun.
 * 4) After accessing the computer area in the south of the level, look toward the southern side of the mainframe to find that there is a small recess. Open it to find 15 health bonuses, three clips, a box of shotgun shells, a backpack and a blue armor (sector 100).

Routes and tricks
This level is one of the few levels in Memento Mori II that can be completed in under a minute. As with designer Alden Bates's MAP10: The Mansion from Memento Mori, this level contains large, open areas with little opposition in proportion to size, with the exception of the platform on which you obtain the blue keycard, which has several enemies in a small space, as well as some tight spaces where you must kill some enemies, or at least stun them with gunfire, to get past them, and obtain a fast time under UV speed rules. Aside from that, you can ignore most of the monsters in this level, including the two Cyberdemons that appear in the red keycard room (some time after you enter it,) and the exit room (after you open up the center of the room,) and zip to the exit in little time. The fastest path to take is the western one; ignore the teleporters when you first enter, and on your way back, enter the southwest teleporter to avoid leaving yourself open to the enemies below. Drop in, stun your foes with gunfire as you obtain the blue keycard, and then proceed to the exit as normal.
