MAP25: Chaos Zone is the twenty-fifth map of Requiem. It was designed by Adam Windsor, and uses the music track "Take All (I have more)" by Mark Klem. It is unusually small compared to many other levels in the megawad, especially at such a late stage.
According to both the text file and the Requiem info pack:
A small fortress over-looking a lake of lava. Probably be a prime piece of real estate for a Demon. Let's see what a pissed off marine with a Rocket Launcher can do to the property values around here....

Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.
Secrets[]
At the beginning of the level, the pillar in the southeast has large holes in its east side. Push that side, and all four pillars will lower, allowing access to three sets of four shotgun shells, and a chainsaw. All four pillars count as one secret. (sector 73)
At the bend in the hallway on your way to the yellow key, there is a lion face in the northeast corner. Press on it to lower a lift holding 40 armor bonuses. (sector 67)
