Mistfall: Heart of the Mists is is a fully cooperative card-based adventure game set in a world of mystery, eldritch powers and perilous adventures. Heart of the Mists continues the story of Mistfall in a standalone expansion featuring new Heroes, Enemies, Encounters and Quests, and introducing Allies, as well as alternative versions of some of the base game mechanisms. At the start of the game each player chooses a hero with a fixed deck of equipment and power cards, as well as a set of upgrades that can be added directly to a players hand during the game. A semi-randomly created board makes for a different landscape every time the game is played, and randomized sets of encounters and enemies create different challenges for players to face before their time runs out.!
