Nessus is a map in the Master Levels for Doom II. It was designed by John Anderson (Dr. Sleep), and is contained in the file NESSUS.WAD.

This level was later ported to PlayStation Final Doom as MAP09: Nessus.

In the version for Doom + Doom II, this level uses the music track "Waiting for Romero to Play".

Walkthrough[edit]

Map of Nessus

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]

Open the door before you. In the room with four lamps open the door in the west. Use the lift.
In the courtyard use either the southern or northern doors with one lamp, then walk upstairs.
Approach the gargoyle door to lower a platform with a Hell knight (or a baron of Hell on Ultra-Violence and Nightmare). Flick the switch to lower the mirror counterpart of this platform in the eastern portion of the map.
Head to the eastern courtyard either by walking through the northern tunnel or walking through the central building or going through the area where you started the level.
Go to the eastern courtyard and climb up either staircase. The door will open automatically. Press the switch to end the level.

Other points of interest[edit]

Secrets[edit]

In the central building in the northern area, pass through the false brick wall and from the ledge jump over to the other side. You can get a soulsphere (or a megasphere on Ultra-Violence and Nightmare) and ammo here. Open the eastern wall and grab the BFG9000. The secret sector is the doorway to the BFG9000 compartment, and is too narrow to step on. See Bugs. (sector 211)

Bugs[edit]

The secret sector is a slim doorway that cannot normally be stood on, making it impossible to register the secret without cheating or exploiting even though the secret items can be accessed without issue. The secret can be registered by use of the idclip cheat code, or by luring the arch-vile up to this area, having it blast you into the BFG9000 compartment (being careful to not let the compartment door shut you in, as this will get you stuck) and then using the save positioning exploit to warp down onto the slim secret sector, registering it.
