MAP31: DejaVu (Memento Mori II)

MAP31: DejaVu is the secret level of Memento Mori II. It was designed by Orin Flaharty and uses the music track "Bavor The Mad" by Mark Klem. The title name comes from the French expression "deja vu", the psychological sensation that you are repeating a situation already seen or witnessed in life. Deja Vu is designed in a techbase style reminiscent of Doom's Knee-Deep in the Dead, hence its title, which comes from the French expression "deja vu", the psychological sensation that you are repeating a situation already seen or witnessed in life.

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) At the beginning of the level, a section of the eastern wall is misaligned.  Open it to find a stairway leading to a room with four health bonuses, a stimpack, a shotgun, and combat armor. (sector 57)
 * 2) In the eastern hallways accessed by the first switch, press upon the wall west of the northern light in the southern hallway to find a secret room with nine health bonuses and a berserk pack. (sector 55)
 * 3) After going through the blue keycard door, open the wall in the northern inset to find a secret hallway. (sector 144) Use the elevator to reach a room with four rockets and two stimpacks, and open the wall at the end of the hallway to access the outdoors area to the north.
 * 4) In the outdoors area accessed from secret #3, there is a misaligned texture on the western wall at the south.  Open it to find a soul sphere. (sector 170)
 * 5) In the red keycard room, there is an arrow made of armor bonuses pointing at a computer panel.  Press on it, and the mainframes to the east will lower to reveal secret compartments.  The north and south compartments both contain a few monsters and a stimpack; the central one contains two rockets and a rocket launcher.  The central one counts as a secret. (sector 224)
 * 6) Once you enter the southern computer room, head into the inset to the north and you will find a lone barrel in front of a computer panel to the east.  Destroy it, and then open the panel behind it to find a computer map.  (sector 222)
 * 7) There is a room near the south of the map that has four holes in the ceiling, to the east of which is a hallway.  Run into this hallway, then return to the north of the previous room to find that a door has opened to reveal a nukage pool.  Cross the pool and you will find a stimpack, as well as eight armor bonuses, a backpack, a light amplification visor, and a door that requires a yellow keycard. (sector 169) After grabbing the yellow keycard, return to this area and open the door to find a hallway leading to an exit switch that takes you to the super secret level, MAP32: Dances with Demons.

Bugs
It is only possible to obtain 99% Kills in this level, as one Imp (thing 349) contained in one of the inaccessible monster storages (which store monsters for teleportation into the level) is glued to a barrel (thing 383) occupying the same space. Whether this was intentional or not is unknown.

Trivia
Unlike another level from Memento Mori II designed in Knee-Deep in |}

Trivia
Unlike another level from Memento Mori II designed in Knee-Deep in the Dead style, MAP24: Io Lab, this level features only Doom monsters. In fact, in DejaVu there is even more restraint than in MAP08: And the Dead Shall Rise from Memento Mori, also designed by Orin Flaharty, as lost souls and cacodemons are also missing. This means that in this secret level the player can only encounter monsters from Knee-Deep in the Dead. Regarding weapons and equipment, the design is slightly less consistent: megaspheres or super shotguns (from Doom II) are absent, but the player can collect a plasma rifle or an invulnerability sphere (present in Doom, but not in its first episode).
