From publisher blurb: The Synergy game system that powers Blue Planet has a quick and simple task resolution that is well suited to the action and intrigue of the Blue Planet milieu. However, there are times when game moderators may want more than a simple success or failure result. The action value subsystem that is already part of Synergy measures degrees of success and failure. This rules expansion will show you how to use action values, adding a system for benefits, complications, and catastrophes to give skill task rolls more variety in your Blue Planet games. This is a rules expansion for the Blue Planet™ roleplaying game. Undercurrents are an irregular publication, covering adventures, technology, fiction, and other articles for use with Blue Planet™. Watch out for more Undercurrents, coming soon from Capricious Games!
