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.

If you absolutely want a pre-written PDF, these scenarios work perfectly with the "doorstep delivery" model:

The last train home doesn't stop at the station. The lights flicker. The passengers vanish one by one. The train enters a tunnel that exists on no map, leading to the Dreamlands or a pocket dimension of Nyarlathotep

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

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. call of cthulhu at your door pdf

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.

Call of Cthulhu: At Your Door is a classic anthology of modern-era scenarios that remains a standout example of how to blend urban horror with the cosmic dread of the Cthulhu Mythos. Originally published in 1990 and designed for the 4th edition of the game, it provides a gritty, investigative campaign framework set in the sprawl of 1990s North America. Narrative and Setting

The collection consists of six interconnected adventures that take investigators from the sterile corporate offices of a suspicious biotechnology firm to the decaying streets of urban ghettos. Unlike many Lovecraftian adventures that rely on ancient ruins and remote villages, At Your Door focuses on the "new" horrors of the late 20th century:

Corporate Greed: Much of the plot revolves around the Landwher Corporation.

Biological Terror: It explores the terrifying possibilities of genetic experimentation.

Urban Isolation: It uses the loneliness of modern cities to heighten tension. Gameplay and Structure

The campaign is praised for its non-linear approach. While there is an overarching plot involving the "Great Mother," players are often given the freedom to pursue leads in different orders.

Investigation-Heavy: Success depends more on finding paper trails and interviewing witnesses than on combat.

High Lethality: In true Call of Cthulhu fashion, the physical and mental threats are severe; players who rush in guns blazing will likely not survive the first few chapters.

Iconic Moments: The "Full Moon" and "The Noose" scenarios are frequently cited by veteran Keepers as masterclasses in building suspense and psychological discomfort. Visuals and Layout (PDF Version)

When looking at the PDF versions currently available (often via Chaosium or DriveThruRPG), the quality is generally high.

Scannability: The digital versions are usually OCR-enabled, making it easy to search for specific NPCs or locations.

Handouts: One of the strongest points of this supplement is the wealth of player handouts, which translate well to digital play or printing for home games.

Old-School Aesthetic: The art and layout retain the 1990s charm, featuring evocative black-and-white illustrations that perfectly capture the "noir-meets-horror" vibe.

At Your Door is a "must-have" for Keepers who want to run a modern-day campaign that feels grounded yet surreal. While some of the 1990s technology (like pagers and floppy disks) might feel dated, the core themes of corporate malfeasance and biological mutation are more relevant than ever. It requires a bit of work from the Keeper to update the mechanics for 7th Edition, but the strength of the writing makes the effort well worth it.

Once the props are delivered, how do you run the game?

Step 1: The Waiting Game Do not acknowledge the delivery in your group chat. When players text you, "Did you leave a creepy letter on my porch?" reply with: "I haven't left my house all day. Are you feeling okay?"

Step 2: The "Pre-Session" When players arrive for game night, do not start with "Last time, on Call of Cthulhu." Instead, ask: "Everyone get their mail this week?" Watch them pull out the physical props you printed from your PDF.

Step 3: The First Sanity Roll As the Keeper, read only the narration. Do not repeat what is in their hands. If a player has a letter that says, "The thing in the basement has three mouths," you simply say, "You look down at the letter. Your hands are shaking. Roll Sanity."
