Two weeks after The Lost Knights, Shadows of Crime focuses on The Dark Hero participating in the Underworld War, traveling through the galaxy and bringing the heads of three factions together; The Exchange, Czerka Arms, and the Hutt Cartel and confront a fourth hidden group responsible for starting the war; the Shadow Space Empire. It is up to the player to join one of them or stay neutral and ultimately decide if the war ends in peace or in death.
