At Your Door is a classic contemporary campaign supplement for the Call of Cthulhu tabletop roleplaying game. Originally published by Chaosium in 1990, this 180-page book is designed for the Cthulhu Now setting, which moves Lovecraftian horror into the modern day—specifically the early 1990s. Campaign Overview
Subtitled "A Campaign of Terror and Madness in the Days to Come," the story centers on Full Wilderness Inc., a wealthy environmental organization that hires the investigators to find Dr. Peter Tait, a microbiologist who vanished after reporting irregularities in his research.
The campaign is primarily set in the fictional California city of Samson, though it also takes players to Toronto, Canada. It features a unique non-linear structure where the first five scenarios can be played in any order, culminating in a sixth and final climatic chapter. Key Scenarios and Content
The campaign is known for its diverse and often bizarre Mythos elements, ranging from biotechnology to cosmic deities.
Landscrapes: A highly-praised chapter involving a monster-infested farm that challenges investigators to contain a rapidly spreading threat.
The Tcho-Tcho: An appearance by this infamous Mythos race, which some Keepers recommend expanding into a larger role.
Cosmic Confrontations: The campaign includes encounters with at least two Great Old Ones and a mysterious "saintly" child leading a cult.
Player Support: The original physical book included 23 pages of perforated pull-out player handouts to enhance immersion. Critical Reception
Reviews of At Your Door are notably mixed. Some critics consider it the best of the Cthulhu Now line for its authentic 90s feel and imaginative scenarios. However, others find it a "mess" of disparate elements—such as Cthonians, a shoggoth named "Mr. Shiny," and bio-attacks—that feel loosely connected without enough forethought. Where to Find It
While the original 1990 print edition is a collector's item, digital versions are often sought by modern players.
Official Digital Copies: You can find current 7th Edition materials and legacy PDFs directly through Chaosium's official website.
Secondary Markets: Out-of-print titles like this are sometimes available via digital storefronts such as DriveThruRPG.
Community Previews: Limited previews and descriptions are sometimes hosted on sites like Scribd or PDFCoffee, though official sources are recommended for the full, high-quality campaign. Review of At Your Door - RPGnet RPG Game Index

H.P. Lovecraft’s “The Call of Cthulhu” is a story built on distance. The horror lies not in a monster bursting through the window, but in the slow realization that humanity is an insignificant speck in an indifferent cosmos. The titular god, Cthulhu, lies dead but dreaming in the sunken city of R’lyeh. His influence spreads through cults, nightmares, and secondhand manuscripts. The terror is epistemological: the horror is in knowing he exists. But what if that distance collapsed? What if, instead of a letter or a bas-relief, the call of Cthulhu arrived as a knock at your door?
To imagine “The Call of Cthulhu at your door” is to subvert Lovecraft’s entire cosmic framework. The original story hinges on delayed, fragmented revelation. The narrator, Francis Wayland Thurston, pieces together a mystery from his granduncle’s papers, a sailor’s tale, and a newspaper clipping. The horror is intellectual, filtered through layers of text. A knock at the door, by contrast, is immediate, personal, and physical. It transforms the unknowable god into a visitor—an impossibility, because Cthulhu is not a being you meet on the doorstep. He is a presence that warps reality from the deep.
Yet the phrase offers a powerful metaphor. In the digital age, Lovecraft’s cosmic dread has found a new home: the PDF. The story’s original publication in Weird Tales (1928) reached a niche audience. Today, a PDF of “The Call of Cthulhu” can appear in your inbox, on your e-reader, or through a shared link. The click of a download is the modern equivalent of opening a forbidden manuscript. The PDF is “at your door” in the sense that it arrives instantly, without the protective buffer of physical distance. You can hold the apocalypse in a file.
This immediacy changes the nature of the horror. When a PDF arrives at your digital door, you face a choice: open it or delete it. To open is to invite the narrative’s madness into your mind. Lovecraft’s protagonists often go mad not from seeing Cthulhu, but from understanding the truth of human insignificance. A PDF replicates that cognitive contagion. Once read, the ideas cannot be unread. The cultists’ chant—“Ph’nglui mglw’nafh Cthulhu R’lyeh wgah’nagl fhtagn”—echoes not from the sea but from your screen.
Moreover, the ubiquity of digital texts erases the traditional gatekeepers of forbidden knowledge. In Lovecraft’s world, arcane books like the Necronomicon are rare, locked away in university libraries or private collections. Today, a PDF of the Necronomicon (real or fictional) is a search away. The “door” is no longer a physical barrier but a password, a paywall, a permissions setting. And those can be bypassed. Cosmic horror in the 21st century is not the horror of the unknown but the horror of the hyper-available: the terrifying truth is always just one click away.
Yet there is a final irony. A PDF, for all its immediacy, is still a document. It cannot knock. The true horror of “The Call of Cthulhu” is that Cthulhu does not need to come to your door. He is already there, in the dreams you cannot remember, in the cultist living next door who seems so normal, in the quiet certainty that the universe does not care. A knock would be a relief—a clear, actionable event. Instead, the call arrives as a file on your desktop, unread, waiting. The question is not whether you will open it. The question is why you already want to.
In the end, the scariest PDF is the one you choose to download. The door was never locked. You just never thought to check.
"Call of Cthulhu at Your Door" is a short story by H.P. Lovecraft, written in 1927. The story revolves around the discovery of a mysterious, otherworldly being known as Cthulhu, and the subsequent horror that unfolds.
The story begins with Robert Blake, a young man who moves into a new apartment in Boston. While exploring the attic of the building, Blake discovers an ancient-looking, non-descript box with a peculiar symbol etched onto it. As he opens the box, he unleashes a malevolent being known as Cthulhu.
Cthulhu is a monstrous, tentacled creature with bulging, green eyes and a grotesque, octopus-like appearance. It is said to be an ancient being from beyond the stars, worshipped as a god by twisted cults. Cthulhu's awakening sets off a chain of events that drives the story forward.
As Cthulhu begins to exert its influence on the world, strange and terrifying occurrences start to happen. People begin to act strangely, as if under some sort of mind control, and the city descends into chaos. Blake soon realizes that he has unleashed a horror beyond human comprehension.
Throughout the story, Lovecraft masterfully crafts an atmosphere of creeping dread and existential horror. The reader is left with a sense of impending doom, as the boundaries between reality and madness begin to blur.
One of the most striking aspects of "Call of Cthulhu at Your Door" is its exploration of the idea that some knowledge is better left unspoken. The story suggests that delving too deep into the mysteries of the universe can have catastrophic consequences.
The story also explores the theme of cosmic horror, which is a hallmark of Lovecraft's work. The idea that humanity is insignificant in the face of an uncaring, eldritch universe is a powerful and unsettling one.
In terms of literary style, Lovecraft's writing is characterized by its use of archaic language and references to ancient, forbidden tomes. This creates a sense of authenticity and adds to the overall sense of unease and foreboding.
The story has had a significant impact on popular culture, inspiring countless adaptations, parodies, and references in film, literature, and art. It has also become a classic of the horror genre, widely studied and admired for its masterful storytelling and atmospheric tension.
In conclusion, "Call of Cthulhu at Your Door" is a masterful tale of cosmic horror that explores the darker aspects of human nature and the universe. Its themes of existential dread, forbidden knowledge, and the insignificance of humanity continue to captivate readers to this day.

At Your Door is a legendary campaign for the Call of Cthulhu roleplaying game that shifted the cosmic horror from the 1920s to the 1990s. Originally published by Chaosium Inc. in 1990, it remains a cult classic for its sandbox structure and unique modern-day Lovecraftian themes. Overview of the Campaign
The campaign consists of six interlinked adventures totaling roughly 180 pages. Unlike the globe-trotting Masks of Nyarlathotep, At Your Door focuses on a more localized, insidious conspiracy involving biological horror and ecological organizations.
The Hook: Investigators are hired by Full Wilderness Inc., a wealthy environmental group, to find a missing microbiologist, Dr. Peter Tait.
The Setting: Much of the action takes place in the fictional town of Samson, California, which serves as a stand-in for Los Angeles.
The Horror: The campaign is famous for introducing Mr. Shiny, a Shoggoth disguised as a human who became an unofficial mascot for Chaosium. Content and Structure
The supplement is designed for "Cthulhu Now," the modern setting for the game's 4th and 5th editions. It includes:
Six Interlinked Scenarios: Players can enter specific chapters multiple times as they uncover deeper layers of the conspiracy.
Sandbox Freedom: The investigators have significant freedom of action, following threads in their own way rather than on a linear path.
Mythos Entities: The campaign features encounters with at least two Great Old Ones and various bizarre creatures resulting from unethical biological experimentation. Modern Utility and PDF Availability
While the physical book is a collector's item often found on sites like eBay, the At Your Door PDF is available for modern Keepers who want to run a "retro-modern" campaign.
Updating to Today: Running the campaign in the 2020s requires some adjustments for modern technology like smartphones and the internet, which can make historical research-based horror more challenging.
Conversion to 7th Edition: Although written for older editions, the core d100 mechanics of Call of Cthulhu have remained consistent, making it relatively easy to adapt the NPC stats and skill checks to the current 7th Edition rules. Modern scenarios (90s, 2000s, onwards) : r/callofcthulhu
