The Fiasco Companion is a supplement for the award-winning game Fiasco, a game inspired by cinematic tales of small time capers gone disastrously wrong. The book includes in-depth discussion of common pitfalls and solid techniques for making Fiasco games excellent as well as advice for writing your own Playsets and hacking the rules. In addition, the Companion features exciting rules variants, new Tilt and Aftermath tables and four new Playsets (Fiasco High, Regina's Wedding, Vegas, and Mission to Mercury).

The book also features a foreword by Wil Wheaton and interviews with an enthusiastic and growing cohort who are already taking the game into the classroom, the writer’s room, and up on stage.
