About the adventure

You all are members of an OK Parliament Comission to inspect "The Devil's Hole" Oil Rig, secretly repurposed by the goverment to excavate the sea inside UK territory for a newly discovered "Rolot Gas" a gas that is much more efficient at producing energy and its located deep into the seabed. You assignment is to evaluate the progress of the project and determine if it is viable to keep it going ot shut it down. Of course, horror will be unleashed at sea and the only question is, will you be able to escape "The Devil's Hole"? This is an adventure designed for convention play, so it should last for one session, 3 or 4 hours long, for 3 to 6 Pregenerated investigators. Beginners are also welcome as well.

What I provide

I will bring my 20+ years of experience running Call of Cthulhu games for different kinds of people, old or young, new or experienced; friends, strangers and strangers who then became friends by playing together. The dice are rolled on Roll20 VTT, characters sheets, portraits, handouts with clues found during play and some illustration. Background music played through the Roll20 web VTT.

Gameplay details

Some combat might come up, nothing crunchy, more cinematic than anything. Since its a one shot we will take the first 30 min or so to talk about the game.
