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's The 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. Review, RPGNet.

    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!
