The Mission

This roleplaying supplement provides rules and guidance for campaigns about hunters who investigate and confront supernatural threats. It covers common situations such as tracking horrors, uncovering mysteries, pursuing enemies, and treating wounded allies, along with cinematic combat rules for firearms, curses, and specialized equipment. A clue-and-deduction system helps players piece together investigations, while advice covers creating monsters, evil organizations, and complex plots. Six sample campaign concepts offer starting points for different types of monster-hunting stories.
