Alone Against the Dark


A solo play Call of Cthulhu mini campaign. No Keeper is needed as you guide yourself through the adventure.

Alone Against The Dark is an adventure for one player, set in the fall of 1931. Your goal is to solve strange disappearances and to forestall a calamity about to beset the world. You will journey from New York City to Greece, Egypt, Germany, and Antarctica.

Inside a Pyramid

Beginning with the theft of a priceless relic, four friends are drawn one by one into a dark web of mystery and horror. As the darkness grows, only you can hold out against the dying of the light. The fate of the world is in your hands.

As Louis Grunewald, a quiet linguistics professor from the Miskatonic University, you will confound the forces of darkness before time runs out—but should Professor Grunewald be eliminated for some reason, you can successively assume the identity of a new investigator. There are four ready-made investigators provided for this purpose, enabling you to take on differing roles as circumstances change in your search for the truth: Louis Grunewald, a linguistics professor from the Miskatonic University, Lydia Lau, a story-seeking reporter for the New York Sun, Devon Wilson, a sailor on leave from the US Navy, and Ernest Holt, a wealthy industrialist.

This adventure is guaranteed dangerous. But, no matter how skillfully you avoid death or madness, your investigators will fail if they do not prevent the turning of the world and the freeing of the City of the Old Ones from the ice.

Armed with a copy of the Call of Cthulhu Keepers Rulebook, a pencil, and some roleplaying dice you are all set for the twists and turns of this epic world spanning adventure. Sit back, get comfy, and prepare to be Alone Against The Dark!

First released over thirty years ago, this new edition has been completely revised and updated for Call of Cthulhu 7th edition, with new illustrations and player aids.

You must have a copy of the Call of Cthulhu Keeper Rulebook 7th Edition to play this adventure.

This really is a great product. It passes my acid test for great fiction: I never want it to end but and perhaps it is my fault for not having a better pdf reader but I feel at least some bookmarks would make me a lot less dizzy scrolling through the pages and having the locations and the character sheets as separate documents would make it easier to tab between the two without scrolling. Totally worth every penny of the price

What has been corrected in the 'corrected' version?

Well, I'm off and... I've hit a snag. If I visit a location that does not specify the amount of time that passes there and I don’t do anything 'extra' how much time has elapsed when I leave? For example, if I arrive at the Arkham Advertiser (60) at noon and just use the phone can I be at another Arkham location by 1PM, allowing one hour to travel to another location on the same location table? Or do I automatically spend a minimum of 1 hour at a location, which would mean the earliest I could be somewhere else would be 2PM? Same with the Bank (3)? How long does it take to make a withdrawal? Is there a queue??? Thanks

According to Mike Mason, there is a standard one hour spent at any location if it isn't specified in the entry. I agree with you though that this can stretch realism in some circumstances, especially in Arkham. Check out my lengthy review on the Chaosium official site under Michael.

Thank you Michael for your response; I wish I'd seen your review earlier but I don't think it had been posted when I last looked. Reassuring to know it's not just me who has struggled with the time keeping element. I don't think it's clear in the starting text at all. I got halfway through the first day and realised things weren't adding up. Given the importance placed on time keeping in the introduction I too was reticent about adopting house rules incase it altered the games progress. I'm now tempted to use my own discretion; in a town the size of Arkham I should be able to visit a location, perform one or two minor tasks and then travel to another location in the space of an hour. In fact, this is what I had started doing as it 'felt right' in character. To balance this out I will adhere to the two one-hour meals per day rule. Let's see how I get on!

I'm loving this but please do some research and ideally consult with a native speaker for scenes and names in foreign countries. I can only speak for German but it's absolutely atrocious. You could at least get place names right, e.g. it's Bremerhaven, not Bremenhaven. This might have been harder when the scenario was first written but these days there is no excuse and a little research/consultation could have been done while updating.

Thank you for the feedback. To be clear, there are very few German words or places used in this book. Bremen and Bremerhaven are the two cities involved in this discussion. Bremen also has its own active "harbor" or "hafen" in addition to relying on Bremerhaven itself. If you consult international shipping maps of the 1920's and 1930's (akin to what the players would have used in the scenario) international shipping routes usually pointed to Bremen itself, such as the route from "New York to Bremen". We acknowledge that such a journey could have included actually embarking/disembarking via the port of Bremerhaven itself before taking other transport to get to the city of Bremen, but those kind of details seldom find their way into shorter adventures such as these.

I'm talking about spelling, not geography, or accuracy of locations. The book uses "Bremenhaven" with n, not "Bremerhaven", with r, which is the correct spelling. You just used it as well. Example: page 70, entry 449 "Bremenhaven, Bremen’s harbor area, appears quiet in the cold air of early morning."
"Sprechen sie Deutsche?" (entry 474) should be "Sprechen Sie Deutsch?" This is all simple stuff.
Further, "Die Frieschutz" should be "Der Freischütz" (Bremen locations, entry 461 etc.). If you can't spell a complicated name, why use it? Not to mention that it's completely out of place. It sounds like the author heard it somewhere and thought it was cool so he used it without checking what it actually means or what it refers to ( Just call an inn by the harbour "Zum Anker" and nobody will ever bat an eyelid.

Do I need the full rulebook to play this or can I get by with just the quickstart rules like with 'Alone Against the Flames'?

The main thing you need the rulebook for is equipment costs when you go shopping but you can probably guesstimate that, as long as you don't go overboard with the stuff you buy.
You only need basic combat rules and the rules for temporary and permanent insanity. Temp insanity is handled differently, too, there are no phobias etc, instead you're out of the game for 1D10 hours.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
