From publisher blurb:
Enter a seedy underworld of alien hyper-capitalists and wondrous ancient artifacts with Quake Alley Mayhem!
This murderous, misshapen module foists a host of traps, puzzles, and environmental hazards upon unsuspecting players in a race against time. Structured for both tournament and campaign play, Quake Alley Mayhem! includes pregenerated characters, supplements to track the party's progress and impending doom, and hooks to fit the adventure into a larger campaign.
Designed for 3 to 6 players of levels 1 - 3 for Gathox Vertical Slum.
