In The Drowned City Campaign Expansion, one to four investigators explore the mysterious and deadly city of R’lyeh as it rises from the ocean’s depths. As players venture into the tomb-like ruin, they’ll scale the city’s crumbling foundations, scour the sea floor for alien artifacts, navigate mind-bending machinery and shifting corridors, and discover an ancient history that was drowned with the city itself. Along the way, they’ll experience a unique story that changes based on their chosen investigators, and it all culminates in a climactic battle against Cthulhu himself!
