HeroCard Nightmare is a surreal psychological thriller in which the last surviving dreamer wins. Nightmare blends deductive, clue-like game play with fast-paced HeroCard duelling, and sets them inside a modular, ever-changing landscape of gothic horror. Nightmare is a HeroCard game, and comes complete with four Hero Card decks. Unlike other HeroCard games, Nightmare does not have any expansion decks, as all four characters come complete within the Nightmare box. Players should still feel free to take their Nightmare characters into other HeroCard games.
