Arkham Horror RPG: Core Rulebook

Step Into the Shadow of Arkham

The streets of Arkham are never truly safe. Beneath the ivy-covered walls of Miskatonic University and behind the shuttered windows of Merchant District townhouses, something ancient and unknowable stirs. The Arkham Horror Roleplaying Game: Core Rulebook from Fantasy Flight Games brings the beloved Arkham Horror universe into a fully realized tabletop RPG experience — where investigators face cosmic dread, unravel conspiracies, and struggle to hold onto their sanity as the truth reveals itself one terrible page at a time.

What's Inside

This is the complete foundation for running and playing Arkham Horror RPG campaigns. Built on a system designed to capture the tension and escalating dread of Lovecraftian horror, the core rulebook provides everything a group needs to create investigators, build cases, and run full narrative sessions set in the 1920s world of Arkham and beyond. Inside you'll find detailed character creation rules covering a range of investigator archetypes — academics, drifters, journalists, and more — each defined not just by skills but by the burdens and drives that pull them toward danger. The game's mechanics emphasize narrative momentum and psychological cost alongside physical challenges, making every investigation feel consequential. The book also includes guidance for the Keeper (the game's Game Master equivalent), with tools for building mysteries, populating the world with threats both human and eldritch, and pacing horror across sessions.

Who This Book Is For

Fans of the Arkham Horror board game, card game, or the broader Fantasy Flight Games Arkham universe will find this a natural next step — the lore, factions, and atmosphere translate directly from the tabletop to the RPG. Experienced roleplayers drawn to horror, investigation, and narrative-driven systems will feel at home immediately. Groups new to RPGs who want a structured, atmospheric experience with strong fiction support will find the Keeper guidance approachable. This is also a strong purchase for readers who love Lovecraftian fiction and want to play in that world rather than just read about it. A second player to act as Keeper is required — this is a group experience, not a solo product.
