The End of DOOM
The End of DOOM plays during the final message after you successfully complete an episode in Doom. Unlike many victory fanfares that leave you with a sense of pride and accomplishment, this tune is dark and dreary.
Its internal name is "D_VICTOR", however, it is titled "The End of DOOM" on Bobby Prince's Doom Music album.
Of all songs in Sega 32X version of Doom, The End of DOOM track could be thought as being the best rank of other tunes - vivid percussions, accurate mood to the DOS version. However, to all of your frustrations, this does not play anywhere in the game.
The reason behind that was likely due to the fact that all of the screens (text with flat texture pattern, in this case) were removed: the first episode ends as normal getting you to the next level, and the second episode lets you beat barons of Hell and Cacodemons in Dis level, but you watch credits playing Sweet Little Dead Bunny instead of it.
