Call of Cthulhuis the world’s best roleplaying game of mystery and horror.
InCall of Cthulhu, you take on the role of everyday people who become investigators of the unknown - whether they are prepared or not. The mysterious places, people, and situations you encounter are often not what they seem - you and your friends are the only thing standing in the way of diabolical cults and cosmic monsters from beyond space.
Call of Cthulhuis a skill-based system with a focus on character development and simple but evocative mechanics.
It uses percentile dice (D100) to determine success and failure, so a Stealth skill of 50 means you have a 50% chance of success. This makes it very simple to understand your likelihood of succeeding at any given task, regardless of your experience with roleplaying games.
When you succeed, you’ll have a chance for that skill to improve as your investigator learns by doing.
In the game, you must work together to solve mysteries, avoid grisly death, and win the day, using the resources and contacts your investigator can find. Sometimes luck is on your side, but, in the end, it’s your choices that determine the fate of your investigator.
