Series: Arkham Horror Files (Fantasy Flight Games)

The year is 1913. The steamship SS Atlantica is two days out from port on its voyage across the Atlantic Ocean. Its unsuspecting passengers fully anticipated a calm journey to Boston, Massachusetts, with nothing out of the ordinary to look forward to. However, strange nightmares plague the minds of the people aboard the ship every night; rumors circulate of dark shapes following closely behind the ship just beneath the waves; and tensions rise when a body is discovered in the ship's chapel, signs of a strange ritual littered around the corpse.

Lurking within the depths of the Atlantic Ocean are a swarm of vicious, unspeakable horrors: the Deep Ones, led by Mother Hydra and Father Dagon. For reasons unknown, they have set their sights on the Atlantica, and their minions, taking the form of human-Deep One hybrids, have infiltrated the steamship to help sink it from within. Each game of Unfathomable has one or more players assuming the role of one of these hybrids, and how well they can secretly sabotage the efforts of the other players might mean the difference between a successful voyage and a sunken ship.

If you're a human, you need to fend off Deep Ones, prevent the Atlantica from taking too much damage, and carefully manage the ship's four crucial resources if you want any hope of making it to Boston, all while trying to figure out which of your fellow players are friends and which are foes. Everyone shares the same resource pool, but humans will try to preserve them while traitors will strive to subtly deplete them. Being able to tell when someone is purposefully draining the group's resources is harder than you think, especially when you take crises into account!

At the end of each player's turn, that player must draw a mythos card. Each of these cards represents a crisis that the whole group must try to resolve together. Some of these crises, such as "Food Rationing", call for a choice that could potentially put the ship's passengers or resources at risk, while others, such as "Hull Leak", call for a skill test in which failure could have disastrous consequences.

During a skill test, each player contributes skill cards from their hand to a face-down pile shared by the group. Once everyone has contributed (or chosen not to), the cards are shuffled, then revealed. If enough of the correct skills were contributed, then the group passes the test! But if the wrong skills were contributed, they can actually hinder the results, leading to failure. Thus, skill tests are dangerous opportunities for traitors to sabotage the humans' efforts, so you have to stay on your toes at all times.

Dunwich Horror is a large-box expansion for the Fantasy Flight Games edition of Arkham Horror, and is a part of the Arkham Horror Series.

Once again, terror has come to New England, this time spreading to the small country town of Dunwich, just a few miles from Arkham. The area is filled with rolling hills, many of which are topped with mysterious stone circles or the ramshackle houses of the recluses who live outside of town. At night, the piping of the whippoorwills fills the air, while lightning bugs dance in the witch-haunted hallows. This is a place where dark pacts with unknown forces are made, and where city folk go to disappear without a trace. But however much the people of Dunwich may distrust outsiders, they desperately need your help against the Horror that has manifested on the Whateley farm...

Dunwich Horror adds 8 Investigators, 4 Ancient Ones, 15 Item cards, 25 Unique Item cards, 21 Spell cards, 11 Skill cards, 5 Ally cards, 4 Condition cards, 28 Monster tokens, 36 Mythos cards and 32 Gate cards to the base set. It also adds new location cards, for a total of 14 cards at each location instead of 7. Dunwich Horror also adds many new mechanics. Players can take a train to Dunwich (a new board that is placed on the end of the Arkham board), which adds 9 new locations and 2 new outer worlds to the game. Players reduced to 0 stamina or sanity have the option of drawing from the Injury or Madness deck, acquiring permanent handicaps, rather than losing half their items and clue tokens. Gates are no longer permanently sealed (a popular house rule in the base game). Condition cards provide benefits to all players may be activated. And, of course, the Dunwich Horror itself - not as strong as the Ancient Ones, yet far stronger than any other monster in the game.

This expansion also features revised rules and an FAQ that addresses many of the perceived faults of the base game. Replacement cards are provided for items and spells that are subject to errata.

The year is 1926, and it is the height of the Roaring Twenties. Flappers dance till dawn in smoke-filled speakeasies drinking alcohol supplied by rum runners and the mob. It's a celebration to end all celebrations in the aftermath of the war to end all wars.

Yet a dark shadow grows in the city of Arkham. Alien entities known as Ancient Ones lurk in the emptiness beyond space and time, writhing at the gates between worlds. These gates have begun to open and must be closed before the Ancient Ones make our world their ruined domination.

Only a handful of investigators stand against the Arkham Horror. Will they Prevail?

Arkham Horror is a cooperative adventure game themed around H.P Lovecraft's Cthulhu Mythos. Players choose from 16 Investigators and take to the streets of Arkham. Before the game, one of the eight Ancient Ones is chosen and it's up to the Investigators to prevent it from breaking into our world. During the course of the game, players will upgrade their characters by acquiring skills, allies, items, weapons, and spells. It's up to the players to clean out the streets of Arkham by fighting many different types of monsters, but their main goal is to close portals to other dimensions that are opening up around town. With too many portals open the Ancient One awakens and the players only have one last chance to save the world. Defeat the Ancient One in combat!
