The Nightmare Deck: Across the Ettenmoors pack is a real antidote for those who have tamed the base scenario and want to feel the adrenaline of a real challenge. It brings 20 new cards that can be swapped with specific cards from the Across the Ettenmoors adventure encounter deck, raising the difficulty level to a true nightmare epic. It's not just another deck; it's an invitation to test creativity, hand management, and each player's skills under pressure. Like most LCG games, the expansion keeps the same cooperative structure that makes the game so beloved: you, the heroes, must unite against the threat, each with unique powers that vary each game. The card swap doesn't change game duration but increases strategic complexity, requiring careful planning of each move. If you've felt comfortable with the standard adventure and want your heart to beat faster, this deck is the right choice. It brings no extra components, just cards, so you don't need to reorganize your play space. The only caveat is that you need the original adventure pack and an Extenso language, as the cards are specific to the scenario. In short, the Nightmare Deck is for those who love Tolkien’s atmosphere, the tension of real combat, and the thrill of overcoming a challenge that seems impossible. Get ready, because the path north is now darker and more perilous than ever.
