They Came From Beneath the Sea


About the adventure

This is a They Came from Beneath the Sea one-shot for Onyx Path Con 2021. "How do YOU like being covered in Old Bay?" The sleepy town of Oxford, MD is home to a cheerful, All-American community. They believe in apple pie and ice cream, in baseball and beer, and summertime crab feasts. But recently, things have been unusual in this small community. Strangers have blown in on ill winds. Dispatched from DC, Federal Agents are on their trail as they set their sights on the Oxford Oceanic Research Center. Are these newcomers communist agents, or something far more sinister?

Additional Details

How to prepare

Microphone required. Characters provided. Players should have their time, attention, Discord account, creativity, and a good time.

What I provide

I will provide a dice roller via Discord, and handouts for Cinematics as well as the Quips deck.

Gameplay details

This game is evocative of 1950s sci-fi B-Movies. The rating is PG, for some language, fully clothed romance, rubbery horror and cheaply produced violence and action. There should not be any racism, sexism, or hateful speech. There WILL be 1950s American jingoism and anti-communist sentiment. There will be violence towards and from aquatic monsters. I will be using X, N and O cards through chat.
