Chaosium inc. Call of Cthulhu: Chaosium 50th Anniversary Slipcase Set

The Complete Call of Cthulhu Experience in a Special 50th Anniversary Collectable Slipcase Set

What’s Inside
The Keeper Rulebook, Investigator Handbook, and Keeper Screen Pack, presented together in a premium collector’s slipcase with all-new cover art celebrating Chaosium’s 50th anniversary.

As steadfast investigators, you travel to strange and dangerous places, uncover sinister plots, and stand against the horrors of the Cthulhu Mythos. You will face sanity-shattering entities, monstrous creatures, and deranged cultists. Within forbidden tomes of ancient lore, you uncover truths humanity was never meant to know.

The Keeper Rulebook
This book contains the core rules, background material, guidance, spells, and monsters of the game. It is an essential reference for Call of Cthulhu and is designed for the Keeper of Arcane Lore—the Game Master who presents scenarios to the players.

The Keeper Rulebook is a true grimoire of rules and inspiration. Inside you will find a bestiary of Mythos entities, two complete scenarios with handouts and pre-generated characters, full rules for the iconic Sanity system, and much more.

The Investigator Handbook
This book expands character creation with over 100 occupations, detailed skill descriptions, and guidance on how to get the most from the game. It introduces organizations investigators may belong to, in-depth information on the classic 1920s setting, and advice for both new and experienced players.

Inside you’ll find full rules for creating unique investigators, roleplaying advice, a primer on 1920s New England—the signature setting of Call of Cthulhu—and much more.

The Keeper Screen Pack
The Keeper Screen Pack enhances play with reference tables, maps, and scenarios that streamline gameplay and deepen immersion in the Mythos.

Included are two ready-to-play scenarios set in 1920s New England, large full-color maps of the world, Lovecraft Country, and Arkham, and a 34-inch Keeper Screen featuring evocative player-facing artwork with essential rules and charts on the reverse.
