Joseph A. McCullough
Game designer behind Frostgrave, Rangers of Shadow Deep, Stargrave, Oathmark, and The Silver Bayonet.
Joseph A. McCullough designed Frostgrave, the wizard warband game published by Osprey Games, and built a family of games on the same d20 engine. That family includes Frostgrave: Ghost Archipelago, Stargrave, Oathmark, and The Silver Bayonet.
He also designed Rangers of Shadow Deep, a solo and co-op adventure game he self-published in 2018. Modiphius now publishes the core book, and he still self-publishes most of its missions. His other games include Deathship One, Operation: Last Train, and Hairfoot Jousting.
