Call of Cthulhu 7e

What has Professor Harris’ research got to do with the strange green fog enveloping the town? Who are the menacing, dark-suited men that arrived on the ferry with your investigator? And, why is a Buddhist monk visiting Esbury, a town more used to entertaining New England’s wealthy elite?

Take on the role of an investigator traveling to a remote lakeside town where strange things are happening. Decide your path through the story, and the fate of the citizens of Esbury!

Alone Against The Tide is a solo scenario. All you need is this book, a character sheet, and you’re ready to begin your horrific trip to the lakeside town in Massachusetts!


Alone Against the Frost is a Call of Cthulhu adventure designed to be played by a single person, where you are both the Keeper and player.

The North Hanninah holds many dangers, and your first expedition may not end in scientific or academic glory. Thankfully, you can try this adventure as many times as you like. The Big Woods are unpredictable, and they hold many different adventures and possible outcomes. Each time you begin anew, you may reallocate Dr. Nadelmann’s skill points. Your knowledge of the hazards ahead will improve your chances, but mere knowledge and skills are not always enough against the forces of darkness!

Alone Against The Dark is an adventure for one player, set in the fall of 1931. Your goal is to solve strange disappearances and to forestall a calamity about to beset the world. You will journey from New York City to Greece, Egypt, Germany, and Antarctica.

This adventure is guaranteed dangerous. But, no matter how skillfully you avoid death, your investigators will fail if they do not prevent the turning of the world and the freeing of the city of the Old Ones from the ice.
