Walkthrough[edit]

Map of Observatory
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Essentials[edit]

Go straight forward (east) until you pass a brick column and reach a wide doorway, then flip the switch on the north wall of this doorway to raise a bridge over the nukage ahead. Cross the bridge and flip a switch on the other side to raise two sets of steps behind you, then go up either staircase to reach the door on the east side of the room. Pass through this door and head south past some monsters to an exit door, then open it to find a couple of zombiemen guarding the exit button on the south wall.

Other points of interest[edit]

Secrets[edit]

  1. Head north from the start and the door will open. Open the next door and head east and north at the fork. Open the brown wall to the left and use the lift to go up to a shotgun, armor bonuses, health bonuses, and a stimpack. Entering this room also opens the northern door, but it will soon close. If you want to open this door again and access secret #2, go into the nukage pit and flip the switch to permanently open the door. (sector 129)
  2. The switch behind the door that opens in secret #1 opens a door behind the caged area to the north. Over there you will find an armor, stimpacks, health bonuses, armor bonuses, a clip and shotgun shells. (sector 107)
  3. Head east from the start and use the south wall on the last gray step before the blue floor. Open the next door to get armor bonuses. (sector 72)
  4. Head east from the start and use the north wall on the last gray step before the blue floor. Open the next door to get armor bonuses and a box of shotgun shells. (sector 65)
  5. In the area to the east with the nukage, enter the northeast passage until you find a terminal. Use it, then return to the room with the nukage to find a hole in the south terminal. Enter it to reach the outside area with partial invisibility. (sector 168)
  6. See secret #5. This is a small sector just under secret #5 and is easy to miss. (sector 49)
  7. Grab the partial invisibility mentioned in secret #3 and go south to a lowering wall. Behind it is a megaarmor. (sector 78)
