Embark on a solo adventure as one of the last Star Marshals, an elite force patrolling the frontiers of the galaxy in the far future. Following the devastating conflicts of the Wars of Unreason, which shattered the human galactic empire, the Galactic Alliance established the Marshals to enforce order, granting them authority to act as executioners. Although the Alliance now publicly distances itself from the program, the need for justice in the Outer Worlds has never been greater, and funding still flows through back channels. You, as one of the few remaining Marshals, have the freedom to decide how to enforce the law, with a license to kill in hand.

Gameplay is driven by a deck of cards that reveal locations to explore and unexpected encounters. Each card may also direct you to specific pages in the 'Casebook', the adventure book accompanying the game, detailing scenarios and dilemmas. The main objective is to accrue 60 arrest points, obtained by capturing or eliminating criminals, to unlock the final confrontations of each case. Combat and skill checks are resolved with dice rolls, adding an element of luck and strategy. With an initial 48-page 'Casebook' included, Star Marshal offers an immersive experience where your choices shape the destiny of justice on the galactic frontier.
