The Truman FIles
The Truman Files is a campaign of high school investigators solving mysteries in a world that grows increasingly more supernatural and violent as they descend deeper into the mysteries of Small-Town Louisiana. Set in a decrepit parish outside of New Orleans, the town hides mysteries and secrets that the heroes dig ever deeper to discover, and they may not like what they find when they get to the bottom of it all.
The game is Veronica Mars (or Brick) on the set of Supernatural in the world of Monster Hunter International. The game uses primarily the Bubblegumshoe engine with a helping of regular Gumshoe filtered through the lens of Night's Black Agents and Trail of Cthulhu. This is very much a game inspired by Suppressed Transmissions, GURPS Cabal, Horror, and Voodoo, and the works of Tim Powers and Larry Correia.
