From the introduction: "Call of Cthulhu is a horror-themed roleplaying game based on the writings of Howard Phillips Lovecraft. [...] The booklet you now hold gives you all the information you will need to create a character for the Call of Cthulhu roleplaying game, as well as a brief overview of how to play the game. Many rules contained in the complete Call of Cthulhu Keeper Rulebook have been omitted from these Cthulhu Quickstart Rules for the sake of brevity." Includes the standard introductory adventure "The Haunting", with revised stats for the 7th edition.
