Murder Mystery Synopsis:

This year, the monsters of the International Monster Association will gather on Mount Immortality for the annual Monster Summit. This secret meeting will be held in the Cave of Misfortune, next to the Glop Lagoon. The monsters will discuss the past year’s success as well as plans for haunts, terrors, and scares for the upcoming year.

Grimoth Jones is rumored to be making an important announcement this year and will also acknowledge the members who are far exceeding what it means to be a monster. You’ve received your summons, and this is where your story begins.

    Great game for teens

    Had the minimum (12), and the game flowed well. I was surprised at how many details the boys remembered from the statements. They all seemed to like it. The 4/10 difficulty seemed appropriate for teens. Requesting guests to dress up in character worked out great, and added a level of fun.

    So much fun. The twists in this one were wild. We had 18 people from all walks of life and everyone had a blast.
