“Behind everything crouched the brooding, festering horror of the ancient town, and of the mouldy, unhallowed garret gable where he wrote and studied…”
  -H. P. Lovecraft, “The Dreams in the Witch House”

Judgement. Temperance. Justice. The Tower.

The soothsayer’s tarot wove a tale of a grim future, hard to put out of your mind. But when you learn that four people have disappeared without a trace from an estate in French Hill, you begin to wonder if this cruel fate is meant only for you, or for the entirety of Arkham…

The Circle Undone is the fourth deluxe expansion for Arkham Horror: The Card Game. Here, your team of investigators delve into the mysteries of Arkham’s past, uncovering its macabre history and the motives of those who dwell in its shadows. This expansion contains a playable prologue, first two scenarios of The Circle Undone campaign, as well as new investigator and player cards to further customize your investigations in the world of H. P. Lovecraft’s Mythos.

"You realise, of course, the utterly stupendous nature of the matter before us. To us, as to only a few men on this earth, there will be opened up gulfs of time and space and knowledge beyond anything within the conception of human science and philosophy."
     –H.P. Lovecraft, The Whisperer in Darkness

Who could have ever guessed that your search for two missing professors would lead to this? The wind howls. Ritual magic vibrates through the air. And the world is ripping apart. Your time is running out. Your doom is fast approaching!

Where Doom Awaits is the fifth Mythos Pack in The Dunwich Legacy cycle for Arkham Horror: The Card Game. Even as its new scenario carries your investigations rapidly toward their climactic conclusion, it dizzies your investigator with a distorted version of reality. The woods outside of Dunwich are changing. You'll find clearings strewn with blood and bodies, rivers frozen solid despite the temperate air, and paths that rip open, revealing chasms through the dimensions and other worlds elsewhere in the void…

Fortunately, you won’t find yourself wholly unprepared for the alien challenges these dimensional rifts represent. Twenty-eight player cards (two copies each of fourteen different cards) offer a range of solutions, provided you've earned the experience points to add them to your deck.

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

"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!

"It seemed that the railway express clerk on No. 5508 had been able to recall an incident which might have much bearing on my loss…"
     –H.P. Lovecraft, Whisperer in Darkness

The Essex County Express is the second Mythos Pack in The Dunwich Legacy cycle for Arkham Horror: The Card Game. Among its sixty new cards, you'll find twenty-eight player cards, including four copies of a new weakness.

You'll also find a thrilling new scenario in which your investigations lead you outside the town of Arkham. While the train you take may offer the fastest transit to your next lead, it may not offer the safest… When the train rumbles, shakes, and lurches to a halt, you and your fellow investigators must race from your car to the engine. If you can't get the train moving in a hurry, you and all the other passengers may fall prey to whatever unnatural things seem to be crawling, shifting, and oozing their way from car to car, growing ever larger as they do so.

Your adventures on the Essex County Express feature a randomized set of locations that greatly enhance the scenario's replayability, meaning this nightmarish ride is one you'll want to take again and again and again!

"Almost eight feet tall, and carrying a cheap new valise from Osborn’s general store, this dark and goatish gargoyle appeared one day in Arkham in quest of the dreaded volume kept under lock and key at the college library—the hideous Necronomicon of the mad Arab Abdul Alhazred in Olaus Wormius’ Latin version."
     –H.P. Lovecraft, The Dunwich Horror

The Miskatonic Museum is the first Mythos Pack in The Dunwich Legacy cycle for Arkham Horror: The Card Game, and it begins with a book…

Somewhere in the Miskatonic Museum, Olaus Wormius’s Latin translation of a book called the Necronomicon lies hidden away, kept locked and secret so that those individuals who shouldn't gain access to it do not gain access to it. When recent events at the university and Clover Club lead you to believe that someone may now be searching for this strange and ancient tome – someone who should not be permitted to delve its secrets – you make your way to the Museum. The hour is late, and the place is locked. But you know you must recover the book before anyone can access its arcane secrets for dark purposes.

The cards and adventure from The Miskatonic Museum grant you access to the Museum and its many exhibitions even while the expansion's twenty-six player cards (two copies each of thirteen different cards) vie for your attention. Will you make use of these cards? How will you make use of them? Several of the cards offer a remarkable focus on long-term benefits over short-term returns, and you'll have plenty of time to incorporate them into your Arkham LCG® campaigns – provided you first succeed on the task at hand. After all, there's something else stalking the museum's exhibits…

“No one, even those who have the facts concerning the recent horror, can say just what is the matter with Dunwich…”
     –H. P. Lovecraft, The Dunwich Horror

Several months ago, three Miskatonic University professors armed themselves with secret knowledge, traveled to Dunwich, and brought an end to the strange and terrifying creature that had been terrorizing the secluded village. Now their story continues in The Dunwich Legacyexpansion for Arkham Horror: The Card Game.

Your mentor, Dr. Armitage, was one of those three professors. When his colleagues go missing, he fears the worst and asks for your help. With its five mini cards and 156 full-size cards, The Dunwich Legacy challenges you to find the missing professors, launching you into a campaign that leads to Miskatonic University, the notorious Clover Club, and beyond.

Five new investigators arrive to offer their services, and you can arm them with fifty-nine new player cards (including a complete playset of each). Pursue new deck-building strategies and new styles of play. You’ll need all the help you can get as you play the expansion’s two scenarios and encounter all manner of new terrors – from backroom thugs and bad luck to arcane hexes and wholly unnatural abominations.

Your team has been divided between the world of the dreamers and that of the waking. You have no way to reach your slumbering allies, and with each passing day the danger grows as some malevolent force threatens to bring both worlds together, tearing each apart in the process. As much as you would trust your fellow investigators with your own life, there is too much at stake. With time running out, you have no other choice but to take matters into your own hands.

"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.

Shattered Aeons is the sixth and final Mythos Pack in The Forgotten Age cycle for Arkham Horror: The Card Game.

In The Forgotten Age, you journeyed to the darkest corners of Central America in search of a lost Aztec city-state. What you found during your expedition may be the greatest scientific discover of the age, but it could also be the Earth's undoing.

Throughout The Forgotten Age cycle, you have tried to set your mistakes to right, chasing answers about the mysterious artifact your uncovered and those who pursue it. Retracing your path south, you have uncovered secrets that threaten your entire understanding of the world, of time, and of humanity's place in the universe. Now, the last and greatest of your questions will be answered in Shattered Aeons. But be wary- mere mortals may not be meant to gain such knowledge and the truths you seek may destroy what little remains of your sanity.

The Boundary Beyond is the second Mythos Pack in The Forgotten Age cycle.

As the thread pulls, the weave unravels. Following the events of Threads of Fate, you are driven from Arkham to Mexico City to find answers about an enigmatic relic and those who pursue it. After a seemingly endless string of failures, it appears the trail has gone cold. But on the very day you are ready to return home, something is wrong—the city has altered. Silver lightning crackles in the sky overhead, and the earth rumbles below your feet. Monstrous entities float just below the clouds and the architecture looks more like something out of a history book than modern Mexico.

The Boundary Beyond scenario skews your idea of reality as the city shifts around you. By using the Explore action to investigate different locations, you may find that time has become destabilized as Modern locations are replaced with Ancient ones. You must discover a way to restore the proper timeline before the city and your fate become completely unalterable. Will you be able to return, or will you become lost in time?
