UPDATE: 

We are nearing completion on FROM THE TIDELESS SEA, our first big expansion (at 280 pages and in final layout) for RAIDERS of R’LYEH! More here: http://raidersofrlyeh.com/design-journal-series/#part-thirty-two-update

SEE A PREVIEW HERE: http://raidersofrlyeh.com/img/ror-preview.pdf

RAIDERS of R’LYEH is a stand-alone roleplaying game and sourcebook in which mercenary rogues explore forbidden frontiers, unearth ancient artifacts, and outwit villainous scum. Derived partly from the Runequest rules that have been released under the Open Game License, the game is crafted to emulate not only adventure in the CTHULHU MYTHOS of H.P. Lovecraft and his circle of influences, but especially the savage and evocative feel of Robert E. Howard’s Mythos and Weird menace stories.

Attention has been made to keep the game mechanics compatible with other percentile systems — while innovating additional rulesets unique to the setting and atmosphere — so those players wishing only to use Raiders of R’lyeh as an Edwardian era adventure sourcebook will have a massive global setting to explore and use in their preexisting Mythos campaign, as well as modular adventure, monster and scenario resources for gaming in 1900-1913. Those players wanting a standalone rulebook with its adventure modes of play, will have a complete toolkit for interacting with the Cthulhu Mythos.

  • A complete sourcebook for expeditions, intrigues and adventures in the pre-Great War Edwardian period (can be used as a rules-independent sourcebook)
  • A wealth of resources about technology, inventions, architecture, weapons, gear, currencies, class structure, etiquette, vehicles, mounts, ports of call, and travel for the period
  • An expansive monster construction kit, with new weird monsters and twists on old favorites from the Mythos, drawn from the works of Lovecraft, Robert E. Howard, M.R. James, William Hope Hodgson, Clark Ashton Smith, Algernon Blackwood, Lafcadio Hearn, among others
  • Hundreds of pages of GM support and world building resources for developing adventures, enemies and organizations
  • A global network of back-alley criminals, controlling gentry, avaricious smugglers and a campaign-spanning conspiracy known only as “The Glove,” drawn from the pre-War era and tradition of Weird adventure
  • Setting creation support — including a collection of organizations from the era, from intelligence agencies to detective bureaus and secret society lodges, as well as ideas for secret factions and cults within these organizations or as separate entities, NPC stats for warlords, criminals, soldiers, spies, thugs, beasts...all the added Kickstarter-backed NPCs and organizations...and more
  • Faction rules, with a complete toolkit for developing your own factions
  • Guidelines for facilitating node-based investigation, using Circles of Influence (derived from other systems), Clue Webs and Scenario Nodes, Networking and Connections rules, and Organization Responses and Hierarchies
  • A robust and extensive chapter on magic, sorcerers, occult works and artifacts from the world of 1910
  • A simple yet robust sanity system integrated into the PC and NPC motives and bonds
  • Options for “pulpier” occultists and occult detectives adventurers — akin to much of Lovecraft’s original material and most of Howard’s, and to the occult detectives in the works of various weird writers such as William Hope Hodgson, Arthur Machen, and so on — for players who want to incorporate pulpier magic into their mythos game
  • New adventurer roles, drives, bonds, and special abilities for players that emulate the period and feel of Weird menace and adventure
  • And much more: new skills, new gear, basic and tactical combat rules, chase rules, etc.
  • Includes an OGL and bibliography of sources, with support for open-ended customization, enabling designers to adapt the game and hack their own settings and derived rules

As a bonus, you receive with your purchase “Dark Swamp,” a 27-page introductory scenario plus an expanded toolkit for developing and using the artifacts, legends, minions and magic of Tsathoggua in your campaign

At over 500 pages, BW, Raiders of R’lyeh comes with a vast assortment of toolkits to build and run your own adventures set in the Mythos!


ABOUT THE PRINT EDITION: What is the difference between the Hardcover B&W Book and Hardcover Color Book (Standard Heavyweight)?

The “Hardcover B&W Books” are printed on 50# white paper, while the “Hardcover Color Book (Standard Heavyweight)” uses a thicker 70# white paper which has better page opacity. Please note that despite being listed as Color, both editions are in black & white. However, some customers notice a discernible difference in quality in the thicker edition, so that option is offered here.

NOTE that the Gamemaster’s Guide & Complete Rules print edition has an alternate “Fire of Asshurbanipal” cover (which may be previewed at raidersofrlyeh.com/design-journal-series).

I snagged the print and PDF bundle when Raiders was up as the DriveThru Deal of the Day (marketing works).

Is there a form-fillable version of the character sheet floating out there? Due to Covid, my group is playing remotely and this is a contender for our next game.

Mike, thanks for the inquiry. Creating play aids such as the ones you’re suggesting is on our to-do list. We’re at the tail-end of layout on our first big supplement for the game — then will be tackling the play aids. It’s possible that others have created them and released them to the wild, but we have not made any official ones yet.

I bought this game when only the pdf was available. Is there some way that I could get a coupon to order the hardcover at the price of the Hardcover + pdf? I love this game and I would definitely get the $59.99 color hardcover, but I don't want to end up paying $100 for the book and pdf.

Sorry, missed this the other day because I was out of town. Sent email tonight. I mentioned in the email that I am looking to get the hardcover color book; I realized in my comment above that I mentioned the B&W price instead of the color price. Again, no worries if you can't do anything; I will get the hardcover one way or the other, but I appreciate your response above anyway!

Does the DT RPG add dust jackets and gold foiled stamping to their printing? I'm curioius how "collector's edition" for Kickstarter will be done via DT RPG.

Jacek B September 21, 2017 6:50 pm UTC
Are comments here moderated? I left a comment with no answer and it's gone now. I was only wondering why after years after backing this project I don't see the final project and since December there was no official word on this project. Game looks great but the way communication and handling how the KS was done - a disaster.

I was a backer of this Kickstarter and just received the final version today. Since I didn't purchase it from the site, I can't give a proper review, but I'd like to briefly give folks an idea of what one can expect from this. Raiders of R'lyeh is set in the Georgian period of the early 1900's, the tumultuous years between the gilded Victorian Age and the carnage of the First World War. It is extremely well written and researched to give the player the proper feel for the setting and provide for them accordingly, be it occult knowledge of the era, or proper period weapons when facing a rough situation. One could develop a character from a number of nationalities - say, for example, an Ottoman archaeologist/mystic (possibly Mevelevi Dervish) investigating horrors in the deserts of the Arabian Peninsula in the final crumbling days of the empire. However, perhaps the greatest selling point for this game are the toolkits/generators. These range from creating eldritch tomes to planar gate locations. Especially useful...See more

Actually, that would be the "Edwardian Age." The Georgian era was roughly the time between the end of Queen Anne's reign, and the Regency period of English history (that is, prior to the period of the Napoleonic Wars). This game is set in the decade prior to World War I, not a hundred plus years earlier -- just in case anyone is confused!

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.
