from the introduction:
This is a module for 4-6 player characters of level 4-6. It is set in a gonzo post-apocalyptic past-future.
What that means, in practical terms, is that it is set in the world presented in Gamma World[ or [rpg=1654 Mutant Future (Encounter Critical could also easily be used, although the setting is Earth, rather than Vanth or Asteroid 1618). Statistics in this module will be given in Mutant Future terms.
Why “past-future”? Because the world in which you, Dear Reader, are reading this 1 diverged from the world of Bring Me The Head Of Frank Sinatra! in early 1988.
Game Masters are advised to familiarize themselves with the general layout of the Las Vegas Strip (the author has done so by the simple expedient of playing Grand Theft Auto: San Andreas) and to listen to some of the music and comedy routines of the Rat Pack.
The latter won't actually help with the module, but will be entertaining.
The scenario includes a "wandering harlot table" which parodies material found in the AD&D Dungeon Masters Guide. This table is available separately.
