The World’s Best Game Of Intrigue, Mystery & Horror!

The Old Ones ruled the earth aeons before the rise of humanity. Traces of their cyclopean cities can still be found on remote islands, buried amid the shifting desert sands, and in the frozen wastes of the polar extremes. Originally they came to this world from the stars. They sleep now, some deep within the earth or beneath the sea.

When the stars are right they shall again walk the earth.

Call of Cthulhu is the world’s best game of secrets, mysteries, and horror. 

Playing the role of steadfast investigators, you travel to strange and dangerous places, uncover foul plots, and stand against the terrors of the Cthulhu Mythos. You encounter sanity-blasting entities, monsters, and insane cultists. Within strange and forgotten tomes of lore you discover revelations that humanity was not meant to know.

You and your companions may very well decide the fate of the world.

The Keeper Rulebook, contains the core rules, background, guidance, spells, and monsters of the game. It is everything you need for Call of Cthulhu at your fingertips, and will enhance all of your games. The Keeper Rulebook is intended for use by the Keeper of Arcane Lore—the Game Master who will present the scenario to the other players.

The other players—the Investigators—will benefit hugely from a copy of the Investigator Handbook, which contains expanded rules for character creation, skills, occupations, equipment, and a primer on 1920’s New England—the signature setting of Call of Cthulhu.

Monsters, Beasts and Alien Gods!

The Dark Young

A bestiary of mythos entities to pepper your Call of Cthulhu scenarios and campaigns. Each entry contains full rules for using that monster in the game. Whether it’s a lowly Mi-Go, a flesh-changing Deep One, or the great Cthulhu himself, you’ll find background details, stats, special rules and spells to effectively dispatch these wicked beasts upon your hapless investigators.

Tomes of Eldritch Lore

The Tome

Whether at your local library, or among the forbidden bookshelves of a twisted cultist, the Keeper Rulebook provides a wellspring of books for your investigators to find. Rules for reading, researching, and discovering spells come alongside detailed entries for over 20 tomes. Every tome listed in the Keeper Rulebook can serve as the basis of its own story, and to inspire your very own cults to face off against your investigators.

Tome - Cthulhu in the Necronomicon

Sanity

The Scream of Sanity

Full rules for the Sanity system that sets Call of Cthulhu apart from other horror games. The Sanity system measures each investigator’s capacity to comprehend the incomprehensible. It mechanizes the way the human brain can break upon discovering mind-bending truths we were never meant to discover. With each loss of sanity, the investigators will change, and their character will shift and grow. Sanity is the backbone of narrative character development in Call of Cthulhu.

Sanity Loss Example

    Ideal rulebook

    Posted by Nikita Karatun on 3rd Apr 2020

    It is just perfect! The structure, the language, the design, the pictures, the quality of the files! Navigation works like a charm, so easy to find your way around. Special thank's for mobi and epub files. To be honest I hate pdf format so much, almost all table top rpgs rulebooks and scenarios are published in it. It's completely insufferable to read them on mobile phone or on standard screen size e-reader and no way to convert them to decent readable format... I'm so glad that you publish your rulebooks in convenient readable formats! Hopefully more and more materials will be published that way!

    Fantastic PDF, or MOBI / EPUB / PRC

    Posted by G. Ramos on 13th Jun 2016

    This is one of the best PDFs I've ever seen of a core rulebook. It has been carefully laid out for readability, includes chapter / section breaks, and comes in multiple formats. I dropped the PDF onto my iPad and phone, the prc onto my Kindle, and the EPUB for working with the text. Best of all, the PDF is not secure, so you can manipulate the pages or extract them to make your own reference documents. This was worth every penny!
