Map of The Deimos Complex
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.


Two alcoves to your left lead to the optional area and going north to the door is too early yet. Head straight west by descending on the stairs. Head to a computer room and go through the wall lamps between. Head left and directly proceed until you come to the dead end with the yellow key. Some monsters will teleport in and several alcove traps will open. Also, the floor in the eastern corridor here becomes nukage pool. Backtrack to the computer room and go back to the area with staircase you have descended earlier. Open the yellow door north.

There is a blue room in front of you. Head left along the corridor and press the green button. Walk into the blue room to find the red keycard unlocked. Now leave this place through the yellow door and return to the computer room and open the red door. By walking on the nukage get to the storage room in the west. Open the red door at the far end. Go left into the alcove and turn around. Flip the lever on the pillar to open the northern door. Walk into this door to find the blue card inside.

Backtrack and use any staircase. Go pass the wall lamps either in the north or south and get to the room with red door. Enter the door and use either tunnel in the south or east. Each tunnel leads you to the tan walls computer room. Head into the south eastern alcove (which was previously closed). Go up on the stairs and open the blue door. Proceed straight towards the door and press the switch inside.


  1. Head west of the starting room and head south. Open the brown wall and you will get to a room with a soul sphere and a backpack. (sector 41)
  2. In the hall north of the starting room, head slightly northwest and lower the north wall to find a switch. After using it, if you have not entered the connecting hall to the red door, do so, then head southeast of this hall to another one leading to a blue door. Before the blue door, you can head outside to get armor bonuses, a box of ammo, and partial invisibility. (sector 96)

Inspiration and development[edit]

  • The level is based on two unfinished levels by Jan Van der Veken. Anthony Soto later assembled the two together, also adding a joining area around the yellow key along with adjusting item placement.
  • It was originally released as a standalone WAD titled Doom Classic 7: The Deimos Complex. It was uploaded by Anthony to the idgames archive in September 2000.
  • The Classic Episode's updated version adds:
