MAP24: Military Base (Console Doom)

MAP24: Military Base is the first secret level of most console versions of Doom, based on the original E1M9: Military Base with modifications made to accommodate consoles' limitations. The author of the conversion is American McGee and the original author of the map is John Romero. The map first appeared in the Atari Jaguar version, and is additionally used in the 3DO, Sega 32X, Game Boy Advance, Sony PlayStation, and Sega Saturn versions.

Despite being a Phobos level, it incorrectly uses a hellish sky from Inferno on the many of the mentioned ports. Whether or not this is an aesthetical feature or an oversight some other console releases use the right sky from the Knee-Deep in the Dead (and those are namely Sony PlayStation, Sega Saturn and 3DO).

In the PlayStation and Saturn ports, this map occupies the MAP56 slot, but it is otherwise identical to the version which occurs as MAP24 in other ports. In all versions of the game, it is reached by finding the secret exit in. Finishing this level will take the player to.

Bugs
As stated above the sky on this level is from Inferno but not from the original episode. In the source code of Doom, a function calculates which sky to use on a level by checking the warp (the number of map). If the map is more than or equal to 18 than the Hell sky is applied to that level. This error was repaired in Sony PlayStation, Sega Saturn and 3DO releases which altogether use normal Knee-Deep in the Dead sky.

In the Game Boy Advance version of the game, the player will not be offered a chance to save the game when entering this level and so it must be finished in the same play session as MAP03. This is most likely a programming oversight related to the fact that it is the only level in that version of the game reached through a secret exit.

PlayStation / Saturn
In the PlayStation release, the sound data for lost souls spat from pain elemental is never loaded into memory on this map resulting in silent attacks of the lost souls (the death and the pain sounds are still preserved, with the former being identical to any projectile hit and the latter being pain state sound of any hellspawn except imp).

In the same version of the game, the eastmost room (three columns and large elevator going up and down) is too tall (height equaling 304 px). Approaching closer to any one-sided wall of the room will cause its texture quietly distort.

Music
The map uses the following music tracks:
