Trust No One! The first expansion to The X-Files Board Game adds new agents, an additional location to investigate, and a new `Monster of the Week` mechanic that brings terror in the form of some of the show`s most iconic serial villains. Tooms, Flukeman, the Peacocks, and more all make appearances as intimidating roadblocks ready to impede the progress of an X-Files agent foolish enough to investigate in their midst.
