About the adventure

It is January 10. 1930. The lot of you are either field agents or contractors for the "Federal Bureau of Investigation" set onto the case of the recent theft of classified documents. Your suspect is said to be hiding in a remote location in Keweena County, Michigan. This means it is impossible to reach by train or Aircraft and may be difficult to get to by Automobile. The journey will be especially treacherous due to snowy conditions. It is most likely that your suspect is still in possesion of the Documents and retriving or destroying them is of highest priority. Your assigned lead is Walter Pinhallow, more information will follow in the pre mission brief.

How to prepare

Voice chat is mandatory for this game. You will have to create a free Roll 20 account if you don't already have one. You also need to have discord as it will be used for voice.

What I provide

Area maps, handouts and music.

Gameplay details

Content Warning: as this is a horror game it will include the expected themes, primarily graphic violence and frightening imagery. But it won't include any themes of sexual violence. X, N, and O Cards are in effect in case something goes to far for someone. This Game will be a slow horror/mystery focusing on Roleplay and Teamwork. Jokes and silliness is allowed, but should be dialed back during tense scenes.
