This is why we call Substratum Protocol a "Solo+" game - we started with a solo system, and built it into a robust multiplayer game.Substratum Protocol supports two styles of solo play - a more complex, free form method similar to playing multiplayer, and the original Hints and Hijinx format of solo play that is quicker to pick up and play through an expedition. Both are a ton of fun and give you room to explore and discover new mysteries on each play through.One thing we love to do with our Hints and Hijinx games is making player artifacts - a dedicated themed journal for the game to document your entire journey in one place. All the members in your team, creatures you meet, dice rolls, adventures, clues, setbacks and successes of your expedition can be captured in a book to look back on or share. Write, draw, color, add post-it notes, and clippings. Make the journal yours! So we created the Expedition Journal. It has room to expand upon who you and your team members are. Document the clues, their location, and the context in which you find them. Track the questions the clues posed to you and your answers. And of course, there are plenty of pages to keep track of the events you encounter, and the rolls you made. At the top of each page you can key your entries back to clues, depth sectors, and events for quick referencing later.At the end, you'll have an artifact wholly unique to you and your expedition. Personnel Folios What is a tabletop roleplaying game without its character sheet? In Substratum Protocol, we have designed three unique bi-folded character sheets we call folios. Our physical folios are printed in full color on nice uncoated papers that can stand up to the rigors of note-taking, erasing, and being tossed in your dice bag after the session. 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.
