The Kingsport Metamorphosis

An Arkham Horror Investigators Gamebook

The Kingsport Metamorphosis

An Arkham Horror Investigators Gamebook

By Jonathan Green

A mysterious letter summons you to the seaside town of Kingsport, where dreams leak into reality, to a wealthy estate transformed into a place of unspeakable nightmares in this new action-adventure gamebook set in the popular world of Arkham Horror.

A thrilling, if odd, request brings the Investigators of Arkham to the estate of wealthy recluse Elijah Harcourt in the mist-wreathed town of Kingsport. Curious to meet your mysterious host, your excitement is dashed when you discover Harcourt’s purpose is far more nefarious than you realized, leaving you and his guests with riddles to solve if you are to survive. As each hour passes, your companions meet terrible fates, forcing you to navigate a spiderweb of betrayal… Choose wisely, Investigator, for your dreams affect your sanity and the path you choose may lead you to a place of nightmares.

See Arkham in a different light as your choices change the story in the all-new Investigators Gamebooks.

Arkham Horror

Arkham Horror

It is the height of the Roaring Twenties – a fresh enthusiasm for the arts, science, and exploration of the past have opened doors to a wider world, and beyond… And 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 thresholds between worlds. Eldritch rituals must be stopped and alien creatures destroyed; before the Ancient Ones make our world their ruined dominion. Only a handful of investigators stand against the horrors threatening to tear this world apart. Will they prevail?
