From Goodman Games:
It is the Age of Cthulhu, and the cold tentacles of primeval madness reach across the globe. A search for a missing socialite leads to the Aokigahara forest at the base of Mount Fuji. Eerily quiet, strangely lifeless, and infinitely desolate, this mysterious forest hosts more suicides than any other location in the world — and, as the investigators will discover, is home to an alien intelligence far beyond our comprehension…
Set throughout the globe and torn from the pages of the hidden history of the world, Age of Cthulhu adventures bring new secrets and mind-bending horrors to your 1920’s Call of Cthulhu game. Each adventure comes with copious player handouts, detailed maps, and pre-generated investigators ready to risk their lives and their sanity to confront the horrors of an uncaring universe.
Age of Cthulhu adventures include many of the classic elements of Call of Cthulhu: action, investigation, and a forbidding sense of horror. Though the adventures utilize real locations and historical events, Age of Cthulhu is first and foremost dedicated to exploring the horrors of the Cthulhu Mythos, and to bringing the excitement of heroic pulp-themed adventure to your gaming table. So dim the lights, load your trusty sidearm, and prepare to venture into the unknown…
