A team of Rebel Alliance operatives has been assigned to steal an Imperial prototype starship. They infiltrate the testing facility and liberate the ship, and their support arrives, leading to a pitched battle and the end to Project Shell-cracker.
Although the Hammer station, one of the two major settings of the adventure, is described as a Rendili StarDrive Firestar-class Orbital Defense Station, the only illustration within the adventure actually depicts a Rendili StarDrive Orbital Construction Dock instead.
