From publisher blurb:
Hey out there cats kittens!
Welcome to the world of Devil Day's, the rocking, demonically imbued, fifties hellscape. Join the ranks of the Damned, join a gang of your fellow devils, and learn how to use your demonic powers to keep the big bosses downstairs happy, and keep those weak humans off of your back.
Devil's Day's is a world book that works with the CHRONOS Universal LARP system. But like with all CHRONOS Skeins (worlds), we keep the genre in the book and the mechanics on the cards. This book contains no mechancis, but instead provides the genre and world story that you can use with the CHRONOS Universal LARP system to host your own events.
