The Martian Investigations

The Martian Investigations are duo of narrative-deduction games - a kind of choose your own adventure game for adults, in which 1-5 players are given total freedom in how they approach the given story. In Death on the Rust Planet and Deep Fears you take the role of Detective Hayley Bendis, who has been sent to a mining colony on the surface of Mars in order to solve a series of grisly murders. The game can be played either on a screen or printed out on paper.
