Your Next Steps

Gateways to Terror

If you’ve purchased and played through the Call of Cthulhu Starter Set, then Doors to Darkness is the ideal next step. After that, you can move on to Gateways To Terror to expand your Call of Cthulhu experience.

Gateways to Terror contains three short-play scenarios for Call of Cthulhu, perfect for beginning and experienced players and Keepers alike. Originally, all three—The NecropolisWhat's in the Cellar? and The Dead Boarder—were designed as demonstration games to give a taste of the game's core motifs—mystery, investigation, and horror—for those with limited time. The scenarios can be played in as little as one hour or be expanded for slightly longer play. Each comes with four ready-made investigators so you can jump right into the action!

What The Critics Say

2017 ENnie winner - Doors to Darkness for Best Adventure

  • "The latest, entry-level product in the Call of Cthulhu tabletop RPG... It includes five new scenarios as well as ten diverse and ready to play investigators. If you can’t tell your fhtagn from your mglw'nafh this sounds like a fabulous place to start."

    — Polygon, Best Tabletop RPGs of 2017.

  • "Where does a new Keeper start from if he has never played Call of Cthulhu before?... All its adventures are straightforward, without complicated subplots, and explore basic principles of the horror genre, while at the same time slowly increasing the difficulty and the interaction with the rules... they are not good just for new Keepers; they work fantastically as one-offs, or in situations with timing considerations (e.g. as events in conventions)."

    — Antonios S., RPGNet Review - Doors to Darkness.

  • "The subtitle is “Scenarios for Beginning Keepers.” The intention here was to provide Keepers fresh to Call of Cthulhu five scenarios to run with extra training wheels. Even if you’ve been at this a while, I highly recommend this book. Primo stuff here."

    — Vintage RPG, An RPG book I have run recently.

  • "Doors to Darkness makes for a great jumping on point to Call of Cthulhu for both beginning Keepers and players. The tales within are each easily completed in a couple of gaming sessions at most and make for excellent introductions to Lovecraftian horror roleplaying."

    — The Gaming Gang, Call of Cthulhu - Doors to Darkness Reviewed.

  • "An impressive way to give a vertical slice of CoC 7e in a tight timeframe..."

    — MJRRPG, The Necropolis Review – Call of Cthulhu (Gateways to Terror).

  • "There are plenty of other big-ticket scenario collections out there that get a lot of praise, and deservedly so. But let’s not neglect the oft-overlooked Doors to Darkness and remember why it’s beloved of new and seasoned Keepers alike: it’s so damn useful."

    — Stygian Muse, Doors To Darkness: Review.

    Well Done - Great Intro

    Posted by Robert Paul on 31st Jul 2023

    These scenarios are really well written and work amazingly well to introduce new players and storytellers. But they also work even for experienced players, too.

    5 Great Starter Scenarios

    Posted by Morgan Hua on 11th Oct 2021

    I've run all 5 scenarios from this book. I've run Ties That Bind multiple times as its solution is fairly unique and fits in a 4 hr convention time slot. Genius Loci is probably my favorite as you can google real pictures and maps of Danvers State Lunatic Asylum. I used None More Black as part of a series of scenarios at Miskatonic U. Servants of the Lake is a creepy motel set in 1920; For what it is, it works. The Darkness Beneath the Hill I felt was the weakest and closer to a dungeon crawl, though there are some great illustrations in it. Overall, a strong set of scenarios.

    A great bunch of adventures for beginner keepers

    Posted by Josh Mitchell on 30th Aug 2021

    The Doors to Darkness book is a lovely hardcover with 5 one off scenarios, some really good others less so. Of the scenarios the stand out is Darkness Beneath the Hill, a fabulous, almost dungeon crawl, adventure that throws your investigators into a basement dwelling mystery. The rest of the scenarios are fun and have a nice mix however the only scenario I wasn't impressed with was Servants of the lake. The premise isn't particularly exciting and the regurgitation of the servants of Gla'aki come off as a poorer Amidst the Ancient Trees with less flavour, places and character, which is in the rulebook. Despite that the book is worth it in my eyes and the other scenarios can be mixed into campaigns here and there.

    Five Great Scenarios for a Campaign

    Posted by Matthew A. on 1st Nov 2020

    These five scenarios are somewhat more involved than the introductory scenarios found in the Starter Set and Quick Start Guide. If a Keeper wants to begin building an ongoing campaign after running the Starter Set material, the DTD scenarios provide an excellent bridge to the more advanced scenarios and full-length campaigns down the road. The standout is "The Darkness Beneath the Hill" which is very pulpy (almost a dungeon crawl) and features the Serpent People!

    Posted by Harry Rothballer on 3rd Feb 2018

    This book is full of five very interesting adventures, I have only ran the first two so far and my gaming group loved every moment. I can't wait to run the next three.
