Map of Necromanteion
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.


Head straight forward into the large room ahead, noting the imps on the ledge behind you, then head east into a corridor and climb the steps to a wooden room with one or two caged cacodemons. Climb the eastern steps to enter a dark tunnel and follow it past some shotgun guys to a room with a chaingun, then head north and go round the corner to get outside. Kill some waiting imps and demons, then go north-west up some steps to enter a marble room and go into the narrow passage in the north-west corner of this room to find the yellow skull key.

Go back to the starting area and open the yellow door on the west side, then head round the corner to find a cacodemon and two demons guarding a rocket launcher. Take the weapon to lower the west wall, then enter the passage behind it to reach a large lava pool with marble paths - you need to reach the skull switch on the red-brick building ahead, but the short path to that switch will drop into the lava when you step on it, so instead take the long path marked by health bonuses. Press the switch to open it and reveal two zombiemen (plus a baron of Hell on Ultra-Violence (UV) and Nightmare (NM) skill levels) guarding a second switch, which will open the door on the west side of the pool, then go through it and follow the hallway round to a teleporter.

Enter the teleporter, quickly kill the demon waiting in front of you (on UV and NM) then enter the next room to see a box of rockets - approach it carefully as it is protected by a crusher. Follow the hall east and north until you see an alcove on your right containing the red skull key, then pick it up to lower the nearby window and create a path back to the lava pool. Go back to the starting area and open the exit door in the north wall, then cross the bridge in front of you to reach the exit switch. (If you fall off the bridge into the lava below, use the bridge to lower it like a lift.)

Other points of interest[edit]

After getting the red key, return to the eastern-most area and step through the damaging blood to reach a red door. Open it and follow the steps up to a plasma gun.


  1. Head north from the start and go north-east behind the column there. Use the wall to lower it and head through. At the other side, head south-east to find a chainsaw. (sector 130)
  2. From the big room at the start, head east to the wooden room. Go to the south-east corner here and lower the wall for a passage leading to a computer area map and energy cells. (sector 13)
  3. In the same room mentioned above, head up the east steps and get on the north-east square, which will lower. Go through the damaging blood to reach shotgun shells and a berserk pack. (sector 214)
  4. In the yellow key room, open the south-east corner to find partial invisibility and shotgun shells. (sector 99)
  5. Head north from the red key and open the east wall to find a radiation shielding suit. (sector 142)
