IDW Games The X-Files: The Board Game: Trust No One Expansion Set;

The first expansion to The X-Files: The 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, each ready to impede the progress of any X-Files agents foolish enough to investigate in their midst! This expansion is not a stand-alone game and requires the base game to use this additional content.
