MAP23: Musical Bar-B-Que is the twenty-third map of 1 Monster. It was designed by Joonas Äijälä (Jodwin) and uses the music track "In the Dark" from Doom II.

Like all maps in the megawad, the map features only one type of monster, in this case the arch-vile. It is set in a dark, brick structure.

This level has significant issues because is not entirely Boom-compatible (see Bugs). This is fixed by 1monster_bugfix.wad as provided in the DSDArchive link below.

Walkthrough[edit]

Map of Musical Bar-B-Que
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]

Pick up the items and go up the lift. Head west and open the door, then head straight on south. Press the lion switch at the end. Go back out of the door and head east. Open the door and go forward; after passing between two red torches, keep going east and open the door on the eastern wall. Enter the teleporter.

In the outdoors area, you need to walk very carefully; there is no way out of the lava if you fall in. You need to press two switches here, one to the north (it is normally blocked by bars, but you removed them by pressing the first lion switch), and one to the south-east. Then escape via the teleporter to the north-east.

To find the red key, leave the room with the teleporter via either of the two doors. In the corridor with three doors to the north, open the eastern one and head through. In this maze-like area, avoid heading through the passages flanked with impaled skulls, as this will trigger an arch-vile ambush. Find a door near the north-west part of this area; it leads to a library. Head north until you come to the blue banner on the wall, then go east. Search the eastern area until you find a skull switch hidden in a nook. The switch opens the wall with the blue banner. Head back there, go inside and press the second skull switch. Now head out of the library and back to the corridor with three doors. This time go through the western door. At the end of the passage you will find the red key, thanks to the skull switch you just pressed.

Go back to the ledge from the beginning of the level and head through the western door again. This time take the passage to the east. At the end of the corridor turn west; descend the stairs (they are accessible thanks to the northern switch in the outdoors lava-filled area), head through the door and claim the blue key. Go back upstairs and go into the room to the north (accessible thanks to the south-eastern switch in the outdoors area). A blue key switch is in this room; press it.

Again head back to the ledge near the start. Now the blue key door to the north is open. Head in, go up the lift and press two skull switches to the west and east to gain access to the red key door. Open the door and press the skull switch at the north end of the room. It opens the exit door which is located at the southern end of the starting area.

Other points of interest[edit]

In the dark corridor with three doors to the north, behind the middle door is armor and several health bonuses.

Secrets[edit]

There are no official secrets in this map.

Bugs[edit]

There are three broken teleporter traps wherein actors are transported on conveyor belts, making it impossible to achieve 100% kills and 100% items when playing on pure Boom compatibility. This is fixed when playing with the patch WAD. Notably, all of these problems disappear when playing on ZDoom, hinting that this level was tested on and intended for ZDoom.

  • When activating the blue button, the associated teleporter trap (sector 50) fails: Two arch-viles are standing exactly on a diagonal teleporter line, invoking the Doom engine's bias to consider them on its back side, which is unintended and means they can never cross the teleporter line when they are moved by conveyor belts. Also in here are two stimpacks, but they are stuck in walls so they cannot get moved by the conveyor belts.
  • When activating the west button to gain access to the red key door, the associated teleporter trap (sector 332) fails to teleport an arch-vile and five health bonuses because these objects are also placed exactly on a diagonal teleporter line causing them to be on an unintended side.
  • Activating the north button starts a mechanism that lets 14 arch-viles move towards teleporters, but they all stop short and fail to teleport, as the mechanism is only in motion for a short time after which the arch-viles stop moving as well.

All teleporter traps in this level are designed with no looping mechanism, meaning that if they are initially blocked, they are guaranteed to be permanently broken with the monster or item stuck out of reach of the player(s).
