Call of Cthulhu RPG: Doors to Darkness

Doors of Darkness features five introductory scenarios for Call of Cthulhu roleplaying. Furthermore, sprinkled throughout each scenario are Keeper Suggestions on how best to run the adventures, overcome possible obstacles, and generally ensure the most fun for all the players. Plus, ten ready-to-use investigators are provided, allowing players to get straight into the scenarios with the minimum of fuss.
