This scenario is designed for six players and can be played in five to six hours.
The story transpires in a cliché-heavy Alien-style setting with several underlying conflicts. When in doubt, think of the films in the Alien franchise or The Thing, etc., and you won't go wrong.
The many sinister aliens, and the accompanying violence and tension, are only meant as framing for a story where the core conflicts are those that arise between the characters.
This version of the scenario is a "recreation" of an earlier version titled "Crawling All Over II" from 1992. It is available as a PDF conversion of an HTML document.
