MAP32: The Hidden Slime Factory is the super secret map of Memento Mori and can be accessed from MAP31: Technology Base. It was designed by Mark Klem, who also composed the level's music track, "The Wind." Due to the way MAP31 is designed, it is impossible to reach this level in single-player gameplay outside of using the level warp cheat, unless the player exploits a design flaw in the previous level.
