ABBADON is a Role Playing Game with an unusual twist; it uses a standard 54-card deck, including jokers, as the determining factor for character actions.

Set in the world of Haven - a dark fantasy world that pays homage to games like Diablo and Darkest Dungeon - players are tasked with taking control of ill-fated and grim heroes, who must battle hordes of undead creatures, monsters, and demons, to prevent the looming darkness from spilling forth upon the world.

This darkness comes in the form of Abbadon, the Lord of Demons himself. In order to ensure their victory, these brave souls will have to explore the depths beneath cities, long forgotten temples and caverns, where they can only hope to find ancient artefacts belonging to Abbadon's loyal servants, or even earn themselves some fortune in gold or magical items that will help aid them along their treacherous journey.
