Often, happenings begin innocently enough, until more and more of the workings behind the scenes are revealed. The players take the roles of ordinary people drawn into the realm of the mysterious: detectives, criminals, scholars, artists, war veterans, etc. For example, the artist character might draw especially well or especially fast, or catch some unapparent detail in the drawing. Rolling 1⁄ 5 or less of the skill level (1-15 in the example) would be a 'special success' (or an 'impale' for combat skills) and would yield some extra bonus to be determined by the keeper. For example, an artist may have a 75% chance of being able to draw something (represented by having 75 in Art skill), and thus rolling a number under 75 would yield a success. Every player statistic is intended to be compatible with the notion that there is a probability of success for a particular action given what the player is capable of doing. The game does not use levels.ĬoC uses percentile dice (with a results ranging from 1 to 100) to determine success or failure. They do not, however, gain hit points and do not become significantly harder to kill. It is skill-based, with player characters getting better with their skills by succeeding at using them for as long as they stay functionally healthy and sane. The system also includes ideas for non-Lovecraft games, such as using folk horror or the settings of other authors and horror movies, or with entirely custom settings and creatures by the gamemaster and/or players.ĬoC uses the Basic Role-Playing system first developed for RuneQuest and used in other Chaosium games. While predominantly focused on Lovecraftian fiction and horror, playing in the Cthulhu Mythos is not required. In keeping with the Lovecraftian theme, the gamemaster is called the Keeper of Arcane Lore ('the keeper'), while player characters are called Investigators of the Unknown ('investigators'). The protagonists may also travel to places that are not of this earth, such as the Dreamlands (which can be accessed through dreams as well as being physically connected to the earth), other planets, or the voids of space. Recent settings include 1000 AD ( Cthulhu: Dark Ages), the 23rd century ( Cthulhu Rising) and Ancient Rome ( Cthulhu Invictus). Cthulhu Now and Delta Green are set in a modern/1980s era and deal with conspiracies.

The Cthulhu by Gaslight supplement blends the occult and Holmesian mystery and is mostly set in England during the 1890s. Lovecraft's observation (from his essay, ' Supernatural Horror in Literature') that 'The oldest and strongest emotion of mankind is fear, and the strongest kind of fear is fear of the unknown.' The original edition, first published in 1981, uses Basic Role-Playing as its basis and is set in the 1920s, the setting of many of Lovecraft's stories. Call of Cthulhu is set in a darker version of our world based on H.
