Map of Ogdoad
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.


This map plays very similarly to Darkdome from Eternal Doom in that it is a large fortress with several defunct switches. The aim is to have the player place markers on the automap whereever there is a gray skull switch to remember its location for later. The eight switches are used to lower the red key. The player must first get to the blue and yellow keys first, then return to the red key room and open the yellow door. The three yellow skull switches in this room will activate each of the skull switches the player has seen, allowing the player to go back and use them to activate the ones in the red key room.

Other points of interest[edit]


  1. Enter the door to the right of the fortress entrance to a big room with several columns. Find the column that has a rusted center and use it to find a box of ammo. (sector 263)
  2. Head straight up from the big column room to the room with bookshelves, then turn right and go outside, then back inside into a room with a single bookshelf. Use it to find an imp (revenant on Ultra-Violence or higher) guarding a medikit and a box of shotgun shells. (sector 618)
  3. Return to the room with several bookshelves and go to the west side of the room. The left side of the leftmost bookshelf has a skull switch. Use it and go back down the hallway. An opening to the right of the stairs leads to a switch, which will open up a passage to the left of the stairs, leading outside to a berserk pack. (sector 301)
  4. Enter the grand hall of the fortress and climb the steps. Look to the south wall and spot the slab of concrete that does not have hieroglyphics on it. Lower it and sidle alongside the wall until you can drop onto the super shotgun. (sector 117)
  5. Press the switch at the base of the cyberdemon's platform in the grand hall, then return to the room south of the grand hall. Head up the steps to the higher ledge and jump to the west and keep going to the next area. Head north to the steps at the bend but look to the right to spot a lit skull switch behind a torch. Shoot it, then head south and around the column. The switch here will lower a lift leading outside, where you can get a rocket launcher, a box of rockets, and shotgun shells. (sector 167)
  6. Now go up the steps past the lit skull switch and use the skull switch here. This will open the north and south compartments, and beyond the north compartment is the way to the red key room. Drop into the mud below and head west towards the door. There are two small rooms to your left; enter the first one you find. Go to the right wall of this room and look north for a tucked-away switch. Shoot it to open the door. Enter and head south for a lift, which you should use to go across and outside to get a box of rockets, a box of ammo, and a box of shotgun shells. (sector 389)
  7. From Secret #6, use the lift to head up, then open the door to the east to return to the room with the skull switch. This time, press the backside of the skull switch to open the way southward. Follow this path as it goes south, then east (across the room south of the grand hall), then north and into a small room with a switch to open the door ahead. Follow this corridor north, jumping across the gap and then up the steps all the way until you reach a switch. Use it, then quickly run east and south a bit until you see an opening. Enter to get a medikit, an energy cell pack, and a soul sphere. (sector 240)
  8. On the way to the blue key, you will reach a four-way intersection near the middle of the fortress, with columns at the northwest and southeast ends. Look to the northwest at the column with two torches on pillars next to the column. The torch at the northwest part of the column is green instead of red. Press on the base of the pillar to lower it and find a tucked-away switch. Shoot it, then run to the northeast area to get a soul sphere. (sector 605)
  9. Once you get the yellow key, turn south and use the yellow switch to open the door. Go through and press the skull switch behind the first torch you see to open up a passage near the drop ahead. Take it for some energy cell packs and a lift leading up to the cyberdemon's platform, where you will find a megaarmor. (sector 510)
