Save Innsmouth is designed as a stand-alone contemporary Cthulhu Hack scenario and can be run as a one-shot adventure over a single sitting from three to four hours of real time. It makes an ideal adventure for convention play or as an introduction to The Cthulhu Hack system. It's also easily adapted for any modern day game system of investigative horror.
Available now through DriveThruRPG.I ran Save Innsmouth for my students at the Tabletop Game Society I founded at the high school where I teach. In honor of Halloween I suggested we break from the D&D 5E campaign I am running to play The Cthulhu Hack.
I must say, running this one shot for my students ranks up there as one of the most tense and satisfying game experiences I have ever had in my 34 years of playing RPGs.
Well done! --- RPGNow Reviewer
