Welcome to the official mod page for "B.D. : Before Diabolus", this mod is currently in heavy development. In this mod, you play as "J", who is also the main character in "The 5 Chapters of Horror" gmod horror map series, in fact, this mod is actually a prequel to "The 5 Chapters of Horror" map series, so make sure to play through the maps first before playing this mod (if you own GMod of course!).
