Night of the Kachina (2007)

This Call of Cthulhu adventure is suitable for a single gaming sessions with any experience level players. It's intended for an event or convention but can easily be integrated into a continuing campaign. This adventure is weighted more toward combat than investigation but does require the players do some basic investigation. As I described it to a friend: "It's got family values, political suck-ups, cocktail parties, possessed dolls, disadvantaged orphans, fire vampires, a sword fight with an evil Spaniard, a cliff jump on horseback, evil Indian Shamans, and it starts with a sanity check! YEE HAW!"

This adventure was inspired by several television shows: "Wild Wild West" (the series, not the movie), "High Plains Drifter", "Purgatory", and "Brisco County Jr.". If you haven't seen them I highly recommend them.
