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.

  • Masks of Nyarlathotep Book - 666-page PDF Omnibus of both volumes

Question... I just bought and downloaded the book and its many files. The file "Masks_of_Nyarlathotep_Handouts_v2.pdf" is a single title page with no handouts. Is this correct?
Customer avatar
Brian B May 08, 2021 7:55 pm UTC
I can confirm the same issue. Handouts v2 is just a title page. However, my bundle included a Handouts v1.1 that has the material. I just don't know if there's supposed to be a 2nd or updated version.

This is a question about what's in the package:
I see there are also 5-6 other 'Masks' products, of jpegs for use on VTT. Are these jpegs of material/images already included in the PDF of the full product, or are they "extra" material?

I appreciate the updated pdf, but could you mention what has actually been changed?

Same question for me, several CoC items updated recently, but no reason why. Thanks.

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.

Are there plans to convert this to any other rules sets (such as Savage Worlds).

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.

Drew makes a good point. I've spent quite a bit more on books I wasn't as happy with.

Dear All,
While not on here there are a couple of reviews of this product out there:

This video is more a beef what he feels is wrong with CoC 7th edition but he discusses MoN 7th edition (not a review)

Christ Almighty! Sixty US Dollars for a PDF with no Bricks & Mortar-style options. Nope on a Rope.

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.

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.

It's 100+ hours of entertainment. Perhaps you would rather go to a 3 hour pro football game. The least expensive ticket is in Buffalo at $75.
Customer avatar
Andrew M November 22, 2021 1:02 pm UTC
And people complain about, and avoid buying, football tickets for this very reason. I buy baseball tickets because they're affordable for an ephemeral product.

I've played Masks. It's great. I won't pay physical price for electronic content. That choice should reward me with a good rate, but the marketplace is full of folks willing to pay.

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.
