Many lost souls have been lured by the secrets hidden within the House on the Hill. Now an ancient relic—a cursed deck of cards—from the darkest reaches of the attic has entrapped you as well! In the Betrayal Deck of Lost Souls standalone game, a player and their fellow explorers must race to defeat the many horrors lurking within the deck. Play Item cards to defeat Omens and Curses, but beware! There may be a traitor in the group, working against the others to unleash the one true Curse.
