Long await is over. It took 3 years but Unknown Beast is finally available at DriveThruRPG as an pdf. Print-on-demand softcover is still under development and will be released later this summer.
Engage with the Mystery: Unknown Beast is unplanned low prep mystery game where the mystery is created and consequently solved by using improvisational tools the rule system provides. This makes starting a new game fast and easy. There is no need to construct or write the complicated mysteries beforehand. Players don’t need design clues, puzzles or intricate plotlines. All this is done in an improvisational manner during gameplay.
Hunt the Beast: The Beast is the mysterious entity and cause behind the mystery and all players take turns playing it. Despite the name, the Beast isn’t always a beastly creature. It can be anything from werewolves to eldritch horrors to cults to demons to secret military facilities to neighbourhood kids playing pranks. Absolutely anything and everything players can imagine can be the Beast and at the beginning of the mystery it’s unknown what kind of Beast the game will involve.
GMless experience: In Unknown Beast players take turns playing the Beast but they don’t have significantly more power over story progression than the investigators have. Every player gets to play the Beast multiple times during a single mystery.
