About Mayhem

Mayhem is a miniatures focused tabletop gaming convention that offers a wide array of games and special events. It is the goal of the Mayhem staff to host a well run, fun and family friendly tabletop gaming convention. Instead of being focused on a specific genre such as historical or fantasy, Mayhem will offer everything so long as it is miniatures focused. We are also pleased to offer miniatures focused board games and role-playing games.

In Memoriam - Michael "Griff" Griffin

It is with heavy hearts that we share news of the passing of Michael "Griff" Griffin.

Griff was one of the founders of Mayhem and Hijinx Gaming Conventions, a dear friend and avid tabletop gamer. Griff could be found around the gaming tables of many conventions throughout the Northeast. In addition, he was the Miniatures Coordinator for Carnage Gaming Convention for more than 20 years, sharing his passion, expertise, and creativity with countless players and gamemasters.

His enthusiasm, kindness, and dedication helped bring Mayhem to life, and his influence will live on in every game we play and every table we gather around. He leaves behind a legacy built on friendship, imagination, and a love of gaming that inspired so many. We extend our deepest condolences to his family, friends, and all who were touched by his generous spirit. He will be profoundly missed.
