Call of Cthulhu: Shadows of the Old Subway

Playing through a pre-written adventure by 1 Shot Adventures with Claude AI as the GM. Descend into the darkness beneath 1918 New York City in this thrilling Call of Cthulhu solo adventure. When subway workers vanish in the newly excavated tunnels, one investigator ventures into the claustrophobic depths to uncover the truth. What starts as a search for missing men quickly spirals into a nightmare lurking in the suffocating darkness. Armed with only a flickering flashlight and fading courage, can our investigator prevent a catastrophic ritual that threatens to drown the world in primordial ooze? Join me for this tense journey through byzantine corridors where cosmic dread awaits around every corner.

A solo actual play of "Shadows of the Old Subway" using Call of Cthulhu 7th Edition rules.
