Final Doom (PlayStation)

The PS1 port of Final Doom is, compared to the PS1 Doom port, sorely lacking in content, only featuring 17 levels from the PC version's 64. 13 levels from the Master Levels For Doom II PC expansion are included to bring the total level count up to 30.

On the plus side, this was the only console version of Final Doom until 2012.

Unused Monsters


The Spider Mastermind is listed in the ending's Cast of Characters and all of its sprites are present in the WAD, but it isn't used in any of the levels.

Unused Graphics
None of the unused stuff from Doom was cleaned up, but the ENERGY texture was utilized.

Sprites


A clean meat hook. A variant of this with bloodied flesh hanging from the hook is used.



A hanging lamp, which doesn't really fit Doom's style at all.

Textures


IDWALL. The WOOD06 texture with two id logo posters slapped on it.



WARN. Two switch patches from the PC version, which interestingly aren't used on any switch textures in this version, repurposed to make warning lights.



WMSWALL. The WALL21 texture with a Williams logo. This was used in the Club Doom secret level in Doom, but goes unused in this version.

Flats


ENERG. Flat variant of the ENERGY texture, which is still unused in this version.



WMSGATE. A teleporter, based on the GATE name, using the Williams logo.

Thing Flags
The Spectre and Nightmare Spectre are actually just Demon things with flags set on them. These flags can actually be used with any thing. The Spectre's flag simply gives the thing additive translucency. The Nightmare Spectre's flag is more impressive: it inverts the thing's colors, gives it subtractive translucency, and doubles its health.
