The Solo Expansion expands on the solo mode in the base game by adding a new solo base deck, a bias die, Automa personality cards, and case-specific card effects that work with every case released thus far. If you're a player looking to get into the nitty gritty of the rules, read on! The new Solo Base Deck is shuffled together with the drafted case cards for the Automa. All the effects on these cards have been written with solo play in mind. The Automa's procedures act like traps that players will have to work around. The Automa is further expanded with additional cards that let players build an Automa player. By selecting a Personality card, a Discovery card, and the Questioning card corresponding to the Automa’s role in the selected case, there are tons of unique Automa effects and combinations to explore. The new Automa rules reduce die rolling and create unique puzzles to work around each witness as players will want to avoid triggering procedures and sidebar abilities that can set them back.
