World's in Trouble? Must be Tuesday

From the introduction:

World’s in Trouble? Must be Tuesday is a roleplaying game that emulates the “Wake Up, Go to School, Save the World” genre of television shows, as popularized by Buffy the Vampire Slayer. Players take the role of students in a high school plagued by the supernatural; werewolves, demons and other creepy critters that prey on the helpless. Every week is fraught with new dangers, so they must band together to survive and push back the forces of darkness. Complicating things (as if just “being a teenager” and “cursed high school” wasn’t enough) is the fact that each of these characters are themselves supernatural creatures, and their monstrous half is constantly vying for control.
