This is a console version
of a PC level.

This level occupies the map slot MAP23. For other maps which occupy this slot, see Category:MAP23.
This level occupies the map slot MAP55. For other maps which occupy this slot, see Category:MAP55.

MAP23: Dis is the final level of Atari Jaguar, 3DO, Sega 32X and Game Boy Advance versions of Doom, based, as a renamed level, on E2M9: Fortress of Mystery with modifications made to accommodate consoles' limitations. The author of the conversion is American McGee and the original author of the map is Sandy Petersen. This level should not be confused with the original PC level, E3M8: Dis, which this level replaces as the end of Inferno.

The level was renamed back to MAP55: Fortress of Mystery in the Sony PlayStation and Sega Saturn versions, and, like the PC version, is now the second secret level in the game, though accessed from MAP15: Spawning Vats instead of E2M5: Command Center. The author of this conversion is unknown. Completing this level takes the player to MAP16: Hell Gate.

In the Sega 32X version of the game, this level can only be accessed if the player completed all the previous levels from the first level without cheating or use of the level selection feature. It is preceded by MAP15: Spawning Vats in this version of the game, as levels 16 through 22 (comprising the entirety of the Inferno episode) were cut due to ROM cartridge size restrictions for this version.

Walkthrough[edit]

Map of Dis
Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.

Essentials[edit]

You start in a room surrounded by four barons of Hell. Head east through the door to a cross-shaped area containing ten cacodemons. At the east end of the room is a brick wall between two gray marble walls - open this brick wall to find a room with several doors. Press the switch on the west wall to open the north door concealing the blue skull key, then open the blue southern door concealing the red skull key, and finally open the red eastern door to get the yellow skull key. You can now open the yellow door in the north-east corner, and press the switch behind it to finish the level.

On Jaguar, 3DO, 32X and GBA, completing this level ends the game. On PlayStation and Saturn, the player will move on to MAP16: Hell Gate.

Other points of interest[edit]

Each of the points in the starting room has a different item in it. Clockwise from north, they are a plasma gun, a rocket launcher, a computer area map, a shotgun, a chainsaw, another computer area map, a backpack and a chaingun. Megaarmor can also be found in the center of this room.

The center of the second room has a soulsphere, surrounded by two boxes of shells and two boxes of rockets. Each side of the cross holds a medikit. The north side also holds a berserk pack, an energy cell pack and a box of bullets. The south side also holds two energy cell packs and a box of bullets. The east side also holds an energy cell.

Secrets[edit]

  1. The final room with a keycard behind each of the doors is counted as secret (sector 3) and is impossible to miss.

Bugs[edit]

  • There are two computer area maps in the starting room and only one can be picked up, so only 75% of items can be picked up at most.
  • The PlayStation port does not have its brightness level toned down for all areas in the level featuring value 144 as carried from Jaguar, and therefore considered an oversight.

Comparison of versions[edit]

Although the original map was geometrically simple enough, this console conversion changes the following:

  • The lava and the water pools in the second room were removed. The soulsphere which was on the water pool remains.
  • The baron of Hell corpses in the second room were replaced with crucified human bodies, and the cage textures were removed.
  • The final room is now much more spacious compared with the original map version. This is done to accommodate the increased player radius. In the same room, all the wall panels were replaced with wooden doors. However, the player still needs to manually press a switch to open the first door with the skull key.
  • There are four new items added in this map version: three energy cell packs and a berserk pack in the cacodemon room.

The PlayStation and Saturn ports feature some additional modifications:

  • The crucified human corpse wall textures were removed, and replaced with marble brick textures.
  • There is an exit switch at the end of the level, instead of a teleporter.
  • At the same room, keycard bars were replaced with skulls, textures exclusively reappearing in these ports as redrawings from the original Doom (similar modification is done on MAP19: House of Pain, MAP20: Unholy Cathedral and MAP21: Mt. Erebus of Jaguar-based levels).
