MAP59: Club Doom is a secret map that appears in the PlayStation and Saturn versions of Doom II which can be accessed from MAP58: The Mansion. This level is unique in many ways. The level starts off as normal until the player ventures more into the level. As the player climbs the staircase leading from the start room, the music changes into a fast and heavy techno beat - the only map in any version of Ultimate Doom, Doom II or Final Doom in which the music changes during play.
