Monster of the Week is a TTRPG system by Michael Sand based on the Powered by the Apocalypse system. It is “an action-horror roleplaying game about hunting down evil monsters” heavily influenced by TV shows like X-Files, Buffy the Vampire Slayer, and Supernatural. You can find out more about the system and pick up a copy of the rule book here.
