The Hidden Chambers expansion offers 4 mini maps that represent secret rooms. Once you find the door and pick its lock, you may enter the gloomy depths to find treasures, special items, or—perhaps—death. These Chamber Boards are set alongside the main game board, denoting a separate floor or level rather than altering an existing room. Depths of the Lost Citadel As well as offering brand new options for scenario designers, the Hidden Chambers Map Expansion also comes with its own special solo/co-op scenarios and an Adventure Mode scenario for the new Citadel map—“In the Depths of the Lost Citadel”. These scenarios require the core/retail version of Conan (or King or Barbarian pledge) and the new Conqueror expansion. Players will assume the roles of hired swords with a mission: enter the lost citadel of an ancient sorcerer and steal a fabled artefact. To manage this dangerous feat, they must avoid traps, uncover secret doors, and battle the unspeakable horrors lurking beneath. And even if they manage all this, it is unlikely the sorcerer will let them leave with their lives. For solo/co-op mode, this expansion will allow players to add an optional scenario to the campaign offered in the Tome of Skelos. -Description by the publisher Actually, the Depths of the Lost Citadel Adventure Mode scenario is included in the Tome of Skelos (pages 60-62).
