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.
