Unveil the secrets of the legend-haunted city!

Investigators on an Ice Road in front of a Car

On the streets of Arkham, the threat of the Cthulhu Mythos is ever-present. A quiet town in New England—home to the prestigious Miskatonic University—Arkham’s underbelly hides criminals, speakeasies, and a witch-cursed history.

What’s Inside?

Call of Cthulhu: Arkham is the definitive guide to the signature setting of Call of Cthulhu.

A Sandbox Setting

Training at the Arkham Station on a wintery day

With 290 locations detailed across 9 neighborhoods, Call of Cthulhu: Arkham is the perfect supplement for a sandbox-style campaign. The book also contains Gossip & Rumors to use as scenario seeds, and over 80 fully-detailed NPCs with their own secrets to discover—investigators will never be without a lead to follow up on!

Call of Cthulhu: Arkham also introduces new rules and skills for Arkham investigators.

What The Critics Say

  • "Call of Cthulhu: Arkham is a triumph, achieving a near-perfect balance between providing fine detail and allowing for Keeper improvisation. It is, all at the same time, a serious game reference, a sandbox, and a source of scenario seeds too numerous to mention."

    — Stygian Muse, Call of Cthulhu: Arkham.

  • "Pretty much every location here has a potential use in a campaign – whether as a target of investigation, a source of employment, a useful resource, or in some other manner... [Call of Cthulhu: Arkham] really takes Keith Herber’s vision forward by making it easier than ever to make use of this material in practice."

    — Refereeing and Reflection, Supplement Supplemental! (Arkham’s Almanac).

  • "Really cool... everything you want from a setting book for Call of Cthulhu"

    — Gamer’s Haunt, A Quick Look at Call of Cthulhu: Arkham.

  • "This is the gold standard for what an RPG supplement should be." “Simply put, a triumph... It perfectly captures that 1920s Americana small-town feel, while also letting all the wonderful Lovecraftian weirdness seep into every fissure and crack. This is a perfectly thought out, well-developed product that has clearly had so much love go into it. A triumph, there's no other way to put it. If you run games of Call of Cthulhu, you need this book."

    — TechRaptor, Call of Cthulhu: Arkham Review - Supplemental Strangeness.

  • "A truly impressive release for Call of Cthulhu."

    This may be Chaosium’s best product yet! An absolutely lovely book, fantastic artwork, plus two large paper maps and the Arkham Advertiser newspaper. So much detail of Arkham and its environs, it is a treasure house of material for Keepers to use in any campaign set in this part of America. One of the town maps is fine for players to use, the second is a Keepers-only version showing “ interesting” details. This is a must-have.

    I saw the Pickmans Model episode of Curios of Curiosities and thought I’d pick this book up just to read for entertainment. Book is so awesome its sucked me into the role-playing game now. Ordered the starter set, two-book bestiary, and tracked down the miskatonic university, dunwhich, Innsmouth, and kingport books. Only a book THAT good can ignite your imagination like that!

    An essential guide for running campaigns in Arkham

    This is probably one of my favourite setting books I have read for any TTRPG. Whether it is locations, NPC's or the lore and history of Arkham there is so much detail and so many things to pull from it is a gold mine for creating your own scenario's. Even if not running a game set in Arkham I would recommend this book as it has so many locations you could easily drop into another town to use in your games.

    Detailed, atmospheric and filled to the brim with possible stories. My Players love the isometric views of the various quarters.

    The production value of this treasure trove is invaluable. Call of Cthulhu Arkham Unveiled is completely fleshed out for Keepers and Players alike, but leaves enough room to add our own Hooks, Mysteries, expansive info to create our Players Horrific Experience. The art is top-notched! The map, the handouts, the paper quality and book binding shows the attention to detail throughout. I absolutely love Chaosium products, and this is one of the best.

    The book brings Arkham to life even better than previous editions. Gorgeous artwork throughout - AND THE EXTRAS! I really love the Arkham Advertiser prop (keen-eyed investigators will see some great easter eggs too). I cannot wait for the next book in this series!
