Like any self-respecting extension, Thematic Adventures allows a broad renewal of the basic game: more than 40 additional bookmarks (including new explorations very requested by the players) to be added directly to those of the basic box. More content for even more varied adventures! But Thematic Adventures is much more than a simple extension! It also offers 4 new ways to play, each in a different universe: Horror: Escape a ferocious and horrifying beast chasing you in the book! Polar: Find and arrest Von X by conducting a police investigation. Fantasy: Explore a fantastic world and prove that you are "The Lus" Science fiction: Travel from book to book like so many worlds that you will explore through space-time portals! —description from the publisher
