"We shall see that at which dogs howl in the dark, and that at which cats prick up their ears after midnight. We shall see these things, and other things which no breathing creature has yet seen. We shall overleap time, space, and dimensions."
     –H.P. Lovecraft, From Beyond

Things are definitely getting weird in Undimensioned and Unseen, the fourth Mythos Pack in The Dunwich Legacy cycle for Arkham Horror: The Card Game…

By the time your pursuit of two missing professors leads you to the scenario from Undimensioned and Unseen, you'll have traveled far from the familiar comforts of Arkham, and you'll have witnessed things you know no one would ever believe. You'll find yourself neck-deep in furtive cultists and their sacrifices, inundated with information about "Ancient Ones" and unholy rituals. And you'll suddenly find yourself forced to destroy terrifying, monstrous creatures that are literally impervious to everything in your arsenal…

A mystery within a mystery, Undimensioned and Unseen may bring you another step closer to your ultimate goal, but you must first track down whatever knowledge or power may allow you to defeat a number of otherwise invulnerable Abominations. And it demands that you complete your investigation quickly—possibly by making use of the Mythos Pack’s new player cards—lest you should no longer be the hunter, but the hunted!

This is not a standalone product. It requires the Arkham Horror: The Card Game Core Set and The Dunwich Legacy deluxe expansion to play.

"I cannot forget Carcosa where black stars hang in the heavens; where the shadow of men’s thoughts lengthen in the afternoon, when the twin suns sink into the lake of Hali; and my mind will bear for ever the memory of the Pallid Mask."
     –Robert W. Chambers, The King in Yellow

A new theater production is coming to Arkham all the way from Paris. Unsurprisingly, it's been all the rage in conversations among Arkham's socialites. But in your efforts to learn more about the play, you've uncovered a darker history. Disappearances. Suicides. Delusions. Insanity. Wherever The King in Yellow is performed, madness follows close behind…

In The Path to Carcosa, the second deluxe expansion for Arkham Horror: The Card Game, it becomes your task to uncover the secrets of this unusual play. The expansion's two scenarios kick off The Path to Carcosa campaign with a trip to the Ward Theatre and an invitation to the formal dinner party hosted by cast and crew. But with every answer you gain and every clue you uncover, you only find yourself falling deeper into mystery and madness.

Along with its new scenarios and encounter cards, The Path to Carcosa introduces six new investigators and sixty-two player cards (including a complete playset of each) that afford you new ways to explore and enjoy the game—even as they challenge you to overcome new weaknesses.

This is not a standalone product. A copy of the Arkham Horror: The Card Game Core Set is required to play.
