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 will all make appearances as intimidating roadblocks ready to impede the progress of an X-Files agent foolish enough to investigate in their midst.
