From the introduction: The player characters are a band of bio-scientists, criminal thugs, and intellectual freedom-fighters. They may operate independently, or be part of a larger organized crime empire. User summary: Characters have three Traits (Attributes): Head, Thorax, and Abdomen. These have numeric values distributed from a points pool. Action resolution uses d6 for individual actions and, intriguingly, a set of custom cards for group or party actions. The cards are not provided in the document, however.
