Substratum Protocol Game & Folio Bundle

This bundle includes the base game and Folio Pack! 

When the anomaly appeared at the Earth's core, the Substratum Protocol was initiated.You are the best and brightest scientists we have left, our last hope to stem the apocalypse. You are the Substratum Expedition Team. Descend. Learn. Survive. A solo+ survival mystery RPG using step-down dice and card draw mechanics, Substratum Protocol is playable as both a solo game or guided by a GM for 2–6 players. Don't forget to grab your Expedition Journal and Character Folios! With players taking on the role of Earth's best remaining scientists, Substratum Protocol is our entry into the Deep Delving Mystery genre (like Subnautica and In Other Waters). On their grueling journey to the center of the Earth, members of the Substratum Expedition will overcome challenges, gain clues and knowledge of the anomaly, discover creatures, aliens, cosmic horrors, and ultimately assemble their final hypothesis to overcome the apocalypse looming before them.

The Folio Pack is perfect for a multiplayer game with 4 players.

Personnel Folio
This folio contains everything players need, including a full rules reference for your Actions, die roles, and exosuit abilities. It allows you to track which clues and knowledge you have, your inventory, current Skill Dice ratings, and more. This is your main character sheet.

Team Folio
A dedicated character sheet for playing solo! When playing solo, you take on the role of the leader of the expedition and the other three members of your team share a single folio. The Team Folio, like the Personnel Folio, has a rules reference just for the solo player and managing their Team.

Mission Control Folio
Mission Control is the Game Master in Substratum Protocol, and because of the collaborative nature of the game, we have built a folio just for them to track the expedition's progress and members' stress, current depths and what pages the events are on for each, and a place to document the Final Hypothesis and the dice associated with the end game. And of course, a rules reference.
