The crime is escalating in Chicago. Mystery and its Legion of fighters seem overwhelmed, and they have to recruit. What if the next superhero was you?

Choose your powers, fight against evil and, above all, increase your reputation: Mystery counts on you!

Mystery is a comic combined with a game, one title in a series subtitled "The comic in which you are the hero". You embody a character in a immersive story in which your choices guide your progress. You have a character sheet akin to those used in role-playing games that tracks your possessions, your special abilities, your coins, and your victory points. In general, gameplay consists in following the comic's panels — which contain clues, riddles and traps — and making choices about where to go and what to do, while using your visual perception to collect clues and be smart enough to resolve the riddles. As in any game, you can lose — sometimes really badly!
