At Your Door is a 180-page contemporary campaign supplement for the Call of Cthulhu roleplaying game, originally published by Chaosium in December 1990. Set in the "Cthulhu Now" era (specifically the 1990s), it features six interlinked scenarios primarily located in the fictional California city of Samson and Montreal, Canada. Content and Structure
The campaign is designed to give players significant freedom, allowing them to enter chapters multiple times as they uncover deeper meanings behind earlier events. Scenarios: The book contains six adventures:
The first five scenarios can be played in any order, while the sixth serves as the final climax.
Notable elements include a bio-attack on a research firm, a biotech company accessing Mythos secrets, and a "rabid" conservation organization.
Key Themes: The campaign tackles early 90s issues such as environmentalism, scientific ethics, bodybuilding, and televangelists.
Entities Involved: Investigators may encounter Rhan-Tegoth, Chthonians, and a unique shoggoth named "Mr. Shiny".
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
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 call of cthulhu at your door pdf
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.
