Call Of Cthulhu At Your | Door Pdf
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
Call of Cthulhu campaign At Your Door is a classic supplement originally published by Chaosium in 1990. Set in the "modern day" (the 1990s), it follows a series of six interlinked adventures where investigators are drawn into a web of corporate greed, biological experimentation, and cosmic horror. Campaign Summary The story primarily takes place in the fictional city of Samson, California
, and Toronto, Canada. It centers on a conflict between two major entities: Full Wilderness, an environmental group, and a biotech company that has tapped into Mythos-related secrets.
The Hook: Investigators are hired by Full Wilderness to find Dr. Peter Tait, a microbiologist who disappeared after reporting scientific irregularities.
The Descent: As the team investigates, they uncover that both the environmentalists and the biotech firm are manipulating Mythos forces. They encounter predatory monsters, a victim of horrific human experimentation who is rapidly transforming, and an unnaturally occurring natural disaster.
The Climax: The campaign culminates in an overwhelming encounter with an Outer God and multiple Mythos entities, often resulting in a lethal "meltdown" for characters who lack high Sanity or extreme caution. Modern Adaptation Ideas
While originally written for the '90s, modern Keepers can easily update the setting to the 2020s by pivoting the themes toward today's concerns:
Climate & Tech: Shift the biotech angle to modern AI, CRISPR gene-editing, or "Greenwashing" corporations.
Isolation: Replacing the 90s-era lack of cell phones with modern tech like satellite hacking or digital surveillance can heighten the paranoia.
Revised Themes: Older versions of this campaign have been criticized for using outdated and problematic racial stereotypes (specifically regarding the Tcho-Tcho people). Modern adaptations typically rewrite these sections to focus on the alien and uncaring nature of the Mythos rather than using real-world ethnicities as villains.

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

Materials: The supplement includes 23 pages of perforated pull-out player handouts. Critical Reception Reviews of At Your Door are notably polarized:
Strengths: Some reviewers consider it the best of the 90s-set "Cthulhu Now" books because it feels authentically rooted in the issues of its time rather than just being a 1920s scenario with modern tech. One scenario, "Landscrapes," is frequently singled out as a highlight for its creative and creepy monster.
Weaknesses: Other critics describe the campaign as a "mess" with disjointed elements and a climax that relies too heavily on gunfights, which some feel violates the game's typical investigative ethic. There is also modern criticism regarding its portrayal of certain ethnic groups, which may require significant rewriting for contemporary play. Review of At Your Door - RPGnet RPG Game Index

PART 5: THE KEEPER’S SCENARIOS (PLOTS)
Use these hooks to start a modern mystery.
Conclusion: The Door is Always Open
The phrase "Call of Cthulhu at your door pdf" is more than a search term. It is a design philosophy. It is the belief that a simple piece of paper, formatted in Century Gothic and stained with a tea bag, can be more terrifying than a CGI monster. PART 5: THE KEEPER’S SCENARIOS (PLOTS) Use these

To enhance the classic At Your Door campaign for Call of Cthulhu
, you can introduce a "Corruption Tracker" feature that leans into the supplement's modern-day themes of biological horror and corporate environmentalism. Feature: The "Full Wilderness" Corruption Tracker
Since the campaign centers on the Full Wilderness Inc. organization and its biological research, this feature tracks the gradual physical and mental degradation of investigators as they are exposed to the "Growth" (the campaign's central biological threat).
The Mechanic: Create a 10-point scale for each investigator.
Exposure: Points are gained when investigators interact with contaminated biological samples, spend prolonged time in "Growth" zones, or fail specific CON rolls during encounters with altered entities. The "Body-Horror" Tiers:
Tier 1 (1–3 Points): Hyper-Awareness. Minor physical changes (e.g., skin feeling oily, sensory sharpening) grant a Bonus Die on Spot Hidden or Listen checks, but a Penalty Die on Sanity rolls involving biological gore.
Tier 2 (4–7 Points): Metabolic Shift. The investigator gains +10 to STR or CON as their body unnaturally strengthens, but they suffer from "The Hunger," requiring massive amounts of raw food to avoid exhaustion.
Tier 3 (8–10 Points): Final Change. The investigator begins to sprout additional vestigial limbs or develops translucent skin. At 10 points, the character becomes a mindless thrall of the Growth and is retired as a NPC. Implementation Tips for the Keeper
Visual Handouts: Use the provided 23 pages of perforated handouts to "stain" or "alter" physically for players as their corruption grows.
Corporate Intrigue: Link the corruption to the "Alternative Rule for Skills" often found in pamphlet adventures, where high corruption might allow an investigator to "Sense Mythos" at the cost of permanent Sanity loss.
Atmospheric Detail: Instead of just calling for a roll, describe the corruption through sensory language—like the taste of "obsidian between the tongue and teeth" or the sound of "odd fluting".
This feature transforms the campaign from a standard mystery into a race against the investigators' own evolving biology, perfectly matching the 90s-era "Madness and Terror" theme of the book.
Bringing the Horror Home: How to Play "Call of Cthulhu at Your Door"
The phrase "Call of Cthulhu at your door PDF" typically refers to a fan’s desire for a quick, accessible, or solo-friendly version of Chaosium’s iconic horror roleplaying game, Call of Cthulhu. It evokes the idea of the eldritch mythos arriving not in a dusty library or a remote island, but right at your doorstep—in your living room, with minimal setup.
Whether you want to introduce friends to the game at a moment's notice or run a scenario set in a single house, here’s everything you need to know.
PART 4: SANITY & THE MYTHOS
The core mechanic of the game. Seeing a corpse or a monster forces a Sanity (SAN) roll.
Sanity Loss:
- The Keeper tells you to roll POW × 5 or less.
- Success: You lose the minimum SAN listed.
- Failure: You lose the maximum SAN listed.
- Bouts of Madness: If you lose 5+ SAN in a single roll, you enter a temporary insanity (lasts 1D10 rounds or 1D10 hours).
Indefinite Insanity: If your current SAN drops below a specific threshold, you may develop phobias or permanent mental conditions.
