Nightmare Decks for The Lord of the Rings: The Card Game allow you to revisit your favorite scenarios cast in the shadows of the game's challenging Nightmare Mode. Featuring deadlier enemies, darker locations, and more terrifying surprises, each Nightmare Deck introduces new, alternate encounter cards and instructions for using them to reshape a scenario's encounter deck. The result? A nightmarish journey through territory you thought you knew, but with twists and turns that will have you on the edge of your seat!Your battle aboard a ship full of Corsairs turns into a nightmarish encounter with a gigantic and terrifying sea monster with The Thing from the Depths Flight Nightmare Deck. A new setup card and encounter cards ensure that every moment of your fight with this creature is a desperate fight for survival, as the ship you're aboard threatens to rip apart and leave you sunk in uncharted waters. But it's not just the Thing's many Tentacles that send you racing toward your doom; you'll face deadlier Corsairs, too, and treacheries that will assuredly drown the unwary!Nightmare Decks are available via FFG's In-House Manufacturing and may differ subtly in appearance and texture from Core Set cards. Players are thus encouraged to utilize opaque or art sleeves while playing in Nightmare Mode.This is not a stand-alone product. One copy each of The Lord of the Rings: The Core Set, The Lord of the Rings: The Card Game - The Grey Havens expansion, and The Lord of the Rings: The Thing in the Depths are required to play.
