Masks Internal Page

Requires the Call of Cthulhu Keeper’s Rulebook (7th edition) to play, and is optionally usable with Pulp Cthulhu.

The original six-chapter campaign featuring adventures in America, England, Egypt, Kenya, Australia, and China have been developed and updated by Mike Mason, Lynne Hardy, Paul Fricker, and Scott Dorward, and feature enhanced and new encounters, sub-plots, and on-point guidance for the Keeper.

The Expedition #1

Now written to be playable with either standard Call of Cthulhu or Pulp Cthulhu, the text guides the Keeper and allows for both gritty or action-packed pulp styles of play.

The Introduction chapter features a new foreword by Mask’s creator, Larry DiTillio, and goes on to provide an overview of the campaign, it’s key players and their goals and differing agendas, and the important locations the investigators will travel to while they seek to understand the mystery unfolding before them. Additional material looks at the dark god Nyarlathotep, his cults, and his role in the campaign. Guidance is also provided on running the campaign, including considerations of historical depictions, pulp or standard play styles, and lethality level (just how much danger should the investigators’ face). Rounding things out is plenty of advice on creating investigators for the campaign, replacement characters, and ten ready-to-play investigators for those wishing to dive straight into the adventure.

Search for Pyramid

Complete with a Brand New Chapter...

Set in Peru, this new scenario takes place in 1921 and provides an exciting introductory prologue to the campaign, where the investigators meet Jackson Elias, the industrious and charming author, whose researches lead into the globe-spanning mystery. Embarking on an expedition to find a lost South American pyramid, the investigators come face to face with ancient horrors that foreshadow the task ahead.

... and Even More!

And for an added bonus, a Grand Conclusion chapter helps the Keeper to determine just how successful the players have been in tackling the dark schemes of Nyarlathotep’s cults, as well as discussing ways to extend the campaign in a variety of ways.

Each chapter has been tirelessly crossed-referenced to help those running the campaign to keep track of the many locations, characters, player handouts, and items thrown up by the players’ investigation. With new appendices collecting spells, tomes, and artifacts, running the campaign is easiest it has ever been.

We have added Detailed New Appendices!

Running Masks of Nyarlathotep has never been easier thanks to these extensive appendices:

  • Travel – detailing travel times across the world, means of transport, rest and recuperation for traveling investigators, travel events, and also guidance for investigators wishing to learn new skills and improve existing ones.
  • Spells – collects campaign-important spells together for handy reference, with over 30 spells detailed. Including Call the Black Sphinx, the Seal of Nephren-Ka, and the Ward of Anubis, to name but a few.
  • Tomes – during their investigations the investigators may come across a wide range of Mythos tomes, each bulging with forgotten and dark wisdom. This appendix gathers all of the tomes encountered in the campaign, with over 20 detailed listings, each providing background the tome, the lore within, and relevance to the campaign’s plot, be it the dreaded Necronomicon or the abhorred Black Tome.
  • Artifacts – just as there are numerous tomes to be discovered, there are also plenty of strange artifacts to be found (some useful, some deadly). Here, fifteen artifacts are gathered, from the Mask of Hayama to the Headdress of Eyes, from the Adornments of Nitocris to the very strange Device of Rods, Wheels, and Mirrors. 

This Massive PDF Package Includes:

  • Masks of Nyarlathotep Book - 666-page PDF Omnibus of both volumes
  • 6-page Keeper Screen you can print out to fit over your existing Call of Cthulhu Keeper's Screen
  • 12-page NPC Portraits pack with 105 portraits
  • 85-page Keeper Reference Booklet

  • High-resolution images of the amazing covers by Sam Lamont and Rhys Pugh
  • 10 Pre-Generated Characters with Character and Background Sheets

Sixty bucks ain't bad. Given the margins needed to make a sustainable profit in tabletop gaming, and paying the best artists and writers fair wages for their best work, I'm actually a bit surprised that the pricetag is so low.

It looks beautiful. Reading well. It is worth the price. However, it has a big downside for me, which I learned after buying.
Handouts are not editable. For me, this is a problem, because I play in a different language - I was hoping that before printing I could easily translate them.

Can't understand why people gripe some much about paying $60. You pay $20 to go see a movie that lasts 2 hours or $10 for a pint at a bar. $60 for an amazing adventure that could give hundreds of hours of entertainment seems like a pretty good value to me.

Customer avatar
Rick M July 09, 2018 7:34 pm UTC
There are many 200 page PDFs for sale on DTRPG that cost about $15-$20. Why would getting a 666 page PDF for about 3 times that cost, and three times that size, be a shock and deal breaker? I suppose we could break this into six 110 page PDFs and sell them for $9.99 each...

Also, the printed hardcover slipcase set goes on sale in a few months.
Customer avatar
Marcelino S July 16, 2018 6:44 am UTC
I can’t wait for the slipcase version. I’m assuming it’s going to be about 120 maybe? But I wouldn’t hate the 6 PDFs for 9.99 each. I think the 59.99 all at once is just a bit hard for people for a pdf. I know it’s worth it’s price. It looks amazing and all the 7th ed books have far surpassed all the other editions. If you guys could break it up into chunks that would be awesome. Either way I’m hoping to get This one day. Thanks for such a great book.

Sad fact: buying it here does not get you the coupon for reducing the price of the printed slipcase books... I wish Chaosium would change their mind about that.
Customer avatar
Rick M July 07, 2018 5:24 pm UTC
Chaosium does not get much, if any buyer data from DTRPG. Nor do we get specific refund related data if the transaction is reversed. We also do not get the same revenue from the sale. All told, that makes it too difficult to offer coupons for the printed books when the PDFs are sold elsewhere.
Customer avatar
William M July 13, 2018 10:04 am UTC
With respect, you can access partial data on unique sales. There are ways of matching transaction codes with customer accounts and refunding in part or full the 60% royalties earnt on the PDF when you sell a printed copy to a customer, regardless of where else you are printing or selling from. It's awkward but do-able. Disappointment for some here might again be linked to expectations over the price of PDF alone. I like the idea that a PDF can be sold as a sort of "early access" to rulebooks, and I have sometimes found that I've bought a PDF on DriveThru and then later bought the hard copies directly from the publisher, to have the publisher then provide access to a pdf through a code or link. In many cases I have not bought the rulebooks until after I have the PDF and accept that this is the way of things, but as an industry there may need to be more consistency in this. For many customers, PDFs can be a gateway for purchasing whole set of physical copies from a range so it makes good business...See more
Customer avatar
William M July 13, 2018 10:37 am UTC
edit: I might be wrong on the refunding through DriveThruRPG, it's certainly not obvious - I was possibly thinking about the POD side of things when orders can be cancelled. But there might be still ways of managing these sorts of deals, and if not, DriveThru/OBS probably owe it to their publisher-customer/clients to be thinking about all manner of solutions like this. :-/
Customer avatar
William M July 07, 2018 11:53 am UTC
Looks great, but it's shame this is $60 (£45gbp) for a PDF. Maybe the price includes some ink cartridges? ;) I'm hoping that there are print friendly versions of the PDFs? I always appreciate the high production values Chaosium provide in their printed books, but this doesn't always translate when it comes to home printing for reference or even easy browsing on a device (when we may be buying the books as well). Despite the bundle -like size, I'd much prefer if Chaosium's products fell within normal price ranges for pdf rules and accessories on sites like these,(after all, we not buying the binding, print cost, materials etc). When you say "tirelessly cross-referenced" does this mean sections and contents are properly hyperlinked? This is the infomation we need. Other than that, congratulations on a great looking product. :)

Excellent, I look forward to acknowledging your 'purchaser' status, your review (after you've read all 666 pages, snatchurally) and the URL of the blog/podcast/youtube channel that you'll be posting the progress of the campaign on.

Oh, and while I am pretty boring, I'm not totes boring, according to my kids.

It's a very odd complaint, not just for the troll-factor of writing comments on a product you have not actually read, but also because one of the strengths of the Masks design from 1st edition onwards was it's propensity towards expansion with add scenarios and locations. The Masks of Nyalathotep Companion that was released to expand the original had about 700+ pages of original material in itself. This new edition adds art, aditional chapters and lends even more weight to what was already an epic campaign. Your criticism seems to be unappreciative of the core strength of this product. And yes, I have purchased this product through the Chaosium site - largely because it adds a discount to the physical product which will be available later.

Tony M July 05, 2018 9:04 am UTC
In 2017 I ran Shadows of Yog-Sothoth, 1982 edition. In the calendar year that we played, twice a month, my group managed five of the seven scenarios. That's 41 pages of material that we thoroughly enjoyed. In 2018 we took a break from CoC to play D&D (BX), Cyberpunk 2020, RuneQuest (2nd Edition) and Marvel Heroes (TSR). In 2019 we'll return to Shadows to finish remaining two scenarios of the campaign and probably play the two bonus scenarios as well. That may well take us most of the year, and that will be alright. We will most likely have got 2 years play out of one 72 page campaign book using a 96 page ruleset and will think ourselves very well served by 35 year old product that is considered to have no value to the market. We, and by we I very specifically mean my friends and I, don't need a 600+ page campaign book. We also don't need a 500- page rulebook to run a game we've been playing for over 30 years. Is it pretty? Undoubtedly. Was it written with love? I think so. I regularly listen to The Good Friends...See more

I don't think it's an odd complaint, and I don't think it's trolling. The point is that the REASON he hasn't read/purchased it is BECAUSE it's too long - and that he would be keen to try a version of more reasonable length. I feel the same way.
Customer avatar
Gareth J July 06, 2018 2:20 pm UTC
Actually, I still play 1st edition (from 1981), and have the original MoN from 1984, but this new release looks good. I will buy it, and read it, and I suggest you give it a try as well before dismissing it in public simply on the basis of page count.

Oh, and I also have the original SoYS from 1982, and would recommend MoN (any edition) over that - too much of it is on rails, although some of the scenarios (Devil's Canyon) are admittedly top class.
Customer avatar
Rory H July 07, 2018 5:32 am UTC
It is. And considering the nature of the complaint being about the time it may take to read or run, it is equally odd that he is spending such an inordinate amount of time complaining about it on this forum. He hasn't bought it, read it or run it. He has no obligation to. So why bother complaining about it?
Customer avatar
ALEXIS G. D July 08, 2018 5:34 pm UTC
You aren't really taking into account that the new episodes are all optional. So, as a Keeper, you have control. As far as I can tell, they haven't added that much to the core campaign, rather, they've enhanced it.
Customer avatar
Tony M July 08, 2018 5:59 pm UTC
It was a quick and simple way to let the publishers know not all of their fans want mega-product.
Customer avatar
Tony M July 08, 2018 6:02 pm UTC
It's all optional, I choose the option not to pay 45 quid for a 666 pdf but pay half that for the original campaign on ebay.
Customer avatar
Rory H July 09, 2018 12:10 pm UTC
You'd be very lucky to get an copy of the original box set at all on eBay, let alone for anything like half the price. You could get one of the later editions (say the 3rd printing). It would have about a third of the page count for sure - but also be second hand, minus the art, maps and other resources made available in the new edition, based on an older version of the rules, in black and white print with a smaller font - all for anything between $20 to a $100 or so? I think most purchasers will know where their money has gone in to with the new edition. Your stance, as a non-purchaser, makes little contribution to anyone seeking real information about a potential purchase. If you wanted to let Chaosium be aware of your frankly feeble point, then you could have just sent them an email.
Customer avatar
Tony M July 10, 2018 6:41 am UTC
I was, cheers, and I look forward to reveling in it's black and white small font goodness, crafted for the version of the rules that I actually play. I'm (kinda?) sorry my offhand comment appears to have upset you so much but visiting DTRPG is part of my daily morning routine and that was more convenient for me. You think my point 'feeble'? No problem, I find you response facile.
Customer avatar
Rory H July 10, 2018 9:40 am UTC
Not just a single offhand comment, though, eh? To reiterate - you neither own, or have read or have run this product. Your single objection is to the page count of an updated edition being larger than the original. You could certainly add 'facile' to 'feeble' in describing this criticism.
Customer avatar
Tony M July 11, 2018 6:09 am UTC
Okay, lets break it down.

One comment made at noon (lunchtime at work) on the 2nd July. That would have been all she wrote if Colin hadn’t decided to pose his question, which DriveThru duly notified me of via the power of a little red ‘1’ on my ‘Account’ tab the next morning.

The only reason that little red ‘1’ was there was because Colin had replied directly to my comment, unlike Casey, who just posted his (totally boring) opinion of me, not the product, by adding a comment, not replying to mine.

Of course, I’m going to look, and off course I’m going to reply to a comment directed at me.

Two days later you wade in, characterise my comment that the product is too long for my utilitarian tastes as ‘odd’ and then label me a troll. For reasons onlyknown to you.

I then take the time to contextualise my attitude and explain why I don’t need over a 1,000 pages of rules and scenarios to run a classic CoC campaign.

Ignored....See more

Perry T July 11, 2018 9:55 am UTC
I too have to question why Tony would make such comments on a product he has never read and says he would never intentend buying.

I have found his responses somewhat vitriol, retrograde and unnessesary.

Any iteration of a product (especially one with such a pedigree as MoN) is bound to bring improvments due to a number of factors; artwork, typface, print quality, paper, handouts, corrections to typos or errors, improvments to storyline (terror australis was an addition to the MoN 1st addition). Should a good product be preserved in aspic, I say no. I for one do not miss the poor quality print and paper of the earlier Chaosium products and welcome the pdf's so we can print the handouts rather than ruining the ordiginal products or making do with crap photocopies.

Its a bit like watch a TV programme you don't like, don't moan just change channels and be happy.

Erik J July 13, 2018 3:50 am UTC
Good lord people. He made a comment about a gaming product. He didn't insult your mother or kick your dog. If he doesn't want it he's free not only to not buy it, but also to say so, just as you are free to post squeals of excitement if you feel so inclined. I would hazard to guess that had he posted something to the effect of, "Squee! So can't wait to try this!" then nobody would be asking him why he "bothered to post." Sometimes I'm really embarrassed to say that I tabletop game, because toxic reactions like this give the community a bad image. He can take a pass on this product, and freely express his reasons why. You can buy both the PDF and the print and extol their virtues. Butter your bread side up, or side down. The world will march onward blissfully ignorant of your differing, and completely compatible, opinions. But practicing civility? That matters.
Customer avatar
Rory H July 13, 2018 9:42 am UTC
So if we all spent our time commenting negatively online on products we have no intention of purchasing and haven't read, but other people might like and are interested in recieving informed ideas about, then the world would be a much more practically civil place? Maybe.

@ Erik - A voice of reason? I was beginning to think I was the last one :-)

@ Rory - I refer the honourable gentleman to the answer I gave some moments ago.

For the record I'm actually quite fond of Chaosium and am glad the CoC 7th ed kickstarter didn't kill them stone dead. I am also very happy that Greg and Sandy are at least involved in the company again. But I'm not really a fan of mega books, not matter how much 'sans-detour' artwork they jam into them.

And I'm still quite pleased with my Tunnels & Trolls joke...

Tony M, Thank you for your comments. I am glad you are happy that Greg and Sandy are now involved with Chaosium again, as am I. They are good guys who put out quality product and have done so for decades. I first met Greg in 1985.

That said, I think you may wish to consider what you post here since Greg and Sandy, and the rest of Chaosium, are almost certain to come here to gauge the response to their latest reworking of this campaign. Why would they not? This is the largest vendor for RPG pdfs. I would anticipate they will be disappointed to read so many negative posts from someone who has not even read the release. They will also probably be upset that your posts may make it difficult for others to come here and find constructive information.
Customer avatar
Tony M July 17, 2018 4:41 pm UTC
Hi Gareth, you're very welcome, but it would help if you contextualised your interest in this. Chaosium employee, DTRPG employee, or just a simple DTRPG customer like myself?

I've never met Sandy but I did meet Greg briefly in the 1990s, and I have to say I'm very doubtful my opinion would bother him in the least. And given what Sandy has weathered through the Cthulhu Wars odyssey I doubt this would raise more than a twinkling smile.

I don't know what it means but it does strike me as interesting that the discussion has 20+ comments but as of writing this the product hasn't received a single review, good or bad.
Customer avatar
Gareth J July 17, 2018 7:13 pm UTC
Hi Tony, I am a customer. Not an otherwise interested party. And like you I am simply waiting for a really good unbiased review, although I am probably biased towards Greg and Sandy to start with. :)

Have a good one.

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.
