From the Introduction
Serenity Adventures is a collection of new scenarios for the Serenity Role Playing Game. As such, the supporting characters in the book are provided with Major and Minor Traits as described in Serenity. Some players and Game Masters might be interested in upgrading their Serenity RPG to the new style of handling Traits with die values, as seen in Battlestar Galactica, Demon Hunters, and the new Cortex System RPG sourcebook.
The following document updates the stat blocks from Serenity Adventures to work with this newer method of describing Traits. For more upgrades, revisions, and rules options, be on the look out for the Big Damn Heroes Handbook later this fall or early spring 2009.
