The Darkness Over Arkham

An Arkham Horror Investigators Gamebook

By Jonathan Green

You are an Arkham Investigator – your choices will decide the outcome of a terrible murder mystery and a sinister plot threatening Arkham – in this brand new gamebook adventure in the world of Arkham Horror

When a renowned professor is found dead, his body melted, it’s up to the Investigators of Arkham to discover what occult horrors were behind his fate. Pick your path, Investigator, and collect allies along the way to hunt down his killer before they strike again. However, Arkham is full of mysteries, with many wishing to keep the truth buried, and who are hungry to usher in a new era full of death and darkness to devour the world you know it. Can you stop it before it is too late?

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

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?

Praise for Arkham Horror

“As always with Aconyte’s impressive (and ever-growing) range, it also finds a satisfying balance between being detailed enough for existing fans of this IP and accessible enough for readers taking their first steps into Arkham Horror fiction. All told it’s fun, suitably creepy, wonderfully varied and consistently entertaining. What more could we ask for?”

Track of Words, on The Devourer Below

“Arkham Horror is shaping up to be one of the most impressive brands being developed by Aconyte, as well as the gold standard to which all tie-in fiction should aspire to and hope to eventually match.”
