The game tells the story of an attack on the town of Devil’s Burden by a horde of monsters. They advance from the Horde Deck towards the town and are opposed by parties of adventurers controlled by each player. The Horde Deck is constructed so that terrifying Boss Monsters will be randomly encountered as the horde advances. When minions and Boss Monsters of the horde are defeated you gain treasures that you can equip on your party to power up!
The game ends when three Boss Monsters have been defeated. The winner is the player who has accumulated the most XP: XP from monsters defeated minus XP from parts of the town destroyed.
