New to Roll20: Gateways to Terror

Posted by Michael O'Brien on 4th Mar 2021

The Call of Cthulhu release Gateways to Terror is now available on Roll20!

Gateways to Terror - Roll20

Three Portals into Nightmare

Gateways to Terror contains three short-play scenarios for the Call of Cthulhu 7th Edition roleplaying game, ideal for beginning and experienced players and Keepers alike. The scenarios can be played in as little as one hour but can be expanded for slightly longer play, and each comes with four ready-made investigators so you can jump right into the action! 

Each scenario includes hints and tips for Keepers new and old, suggestions for additional investigators for larger groups, and a summary of the key rules needed to play.


Gateways to Terror contains three one-shot scenarios for Call of Cthulhu 7th Edition as well as a chapter of advice for Keepers preparing to run a session for new players.

The Necropolis - What ancient horrors lie slumbering in a newly discovered tomb deep in Egypt's Valley of the Kings? Are you allowing local superstitions and the unfortunate events surrounding the opening of Tutankhamen's tomb to play on your mind as you wait to step down into the darkness…

What's in the Cellar? - Did a respected businessman really commit the bloody murder of his beloved wife in the cellar of the family's ancestral holiday cabin? While the body has never been found, it seems like the criminal has been caught. Is a terrible injustice about to be served? Just what happened in that cellar?

The Dead Boarder - And, what has happened to that nice, quiet neighbor of yours? You’ve not seen hide nor hair of him in days! He wasn’t always the friendliest of sorts, but he did seem very pious, what with all the late-night prayers coming from his room…
