MAP15: The Devil's Coterie (Memento Mori II)

MAP15: The Devil's Coterie is the fifteenth level of Memento Mori II. It was designed by Adam Windsor and uses the music track "Frivolous Encounter" by Mark Klem. It contains a separate area for multiplayer competition.

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


 * One of the first areas to be overrun by the Demons in this latest infestation was an old UAC industrial and storage facility. We managed to have some reconnaissance pictures taken of the exterior, the clearest of which has been provided for this briefing. Although at that time the Demons were keeping out of sight, and we were unable to get any hard data on their numbers or strength, recent long range scans suggest significant infestation, and energy discharges matching those of teleport units in action have been detected. We anticipate a very hot reception for you.  Watch your six, and don't be caught napping - there's no telling what traps the Demons have in store.

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) On the walkway north of the area where you obtain the blue keycard, there is a section of wall bearing a yellow stripe.  Open it to discover a set of shells and a box of ammo. (sector 457)
 * 2) In the hallway at the south of the map, there is a candle set in the southern wall.  Press on it to lower an elevator nearby with four rockets. (sector 312) Note that it looks like there is only one, since all of the rockets occupy the same space, but there are actually four.
 * 3) When you enter the hallway with the scrolling UAC walls, they will open to reveal red walls covered in anguished faces.  There is a portion of the eastern wall that isn't; open it to find four sets of shells, and two rockets. (sector 436) Flip the switch to exit the room if the walls close before you leave.
 * 4) In the northeast corner of the room with the blue and yellow keycard doors, one of the computer towers is silver.  Press on it and it will lower to reveal a box of ammo. (sector 170)
 * 5) In the computer room immediately following the blue keycard door, there is a set of bars in the southwest corner.  They can be opened to reveal a strip containing two rockets and a stimpack. (sector 464)
 * 6) In the dark, brick room at the center of the map, there are flickering lights in the northeast corner.  Press on the wall here, and you will be lowered into a small compartment containing two chaingunners, two cells, a stimpack, and a computer map. (sector 86)
 * 7) At the room covered with metal panels south of the western toxic pool area, there is a wooden portion of the wall to the east, in contrast to the stone covering the other walls.  Open this to find a switch. (sector 486) Flip it to lower one of the light poles to the north, allowing you to access a megasphere.
 * 8) In the southeast computer area, a broken panel can be found on a portion of the northern wall underneath flickering lights.  Open it to obtain four rockets. (sector 381)
 * 9) Although it is not required to access this secret, if you run off the elevator in the metal panels room onto the metal poles in the western toxic pool area, and grab the armor bonus, a switch will appear in the yellow keycard room beside the elevator back to the dark brick room.  If you flip it, in the final area of the level, there will be a bright arrow pointing to the section of wall with the exit sign.  This wall can be opened to reveal an exit switch leading to the secret level, MAP31: DejaVu. (sector 371)
