Hello, I am Cthulhu Architect and I design modern maps for RPG games. My maps are pretty generic and can be used in several RPG like Call of Cthulhu, Shadowrun or any other modern game.
If you love Call of Cthulhu by Chaosium Inc. as I do you will surely enjoy my custom maps for many official scenarios. You can find my Scenario Map Packs on Miskatonic Repository on DriveThruRPG. These are Map Packs that contain all the maps you need to play an official Chaosium Inc. Call of Cthulhu Scenario.
If you would like some free maps I am posting new maps regularly on my Patreon page. If you enjoy my maps please consider supporting me.
