From publisher blurb:
‘Synth’ is a collective term for an array of extremely human-like androids manufactured and programmed by various galactic mega-corps. Galaxy Command reluctantly tolerates the creation and employment of Synth servants in a variety of fields. Synths do work too dangerous or ultraspecialized for humans; Synth engineers work in hazardous waste disposal, maintain starships and plot their course while human crewmembers are in coldsleep, terraform inhospitable planetoids. In dark corners of an otherwise bright galaxy, sex-Synths work as prostitutes and strippers, occasionally escaping into a new and more dangerous life as a criminal or space pirate. Synths allow players to create android in the same spirit of Seventies sci-fi that informs the Galaxy Command campaign setting as a whole.
