Sword of the Stars: Born of Blood is a 2007 turn-based strategy expansion for PC, developed by Kerberos Productions as the first add-on to the Sword of the Stars franchise. The expansion introduces the Zuul, a new aggressive alien race, alongside a substantially expanded roster of weapons, ships, and technologies. Players gain greater control over planetary management, adding a layer of tactical depth to the base game's empire-building mechanics. The Zuul's inclusion reshapes the strategic landscape, offering both a new playable faction and a distinct threat for existing races to contend with. The expansion builds directly on the foundation of the original game, broadening its scope through additional content rather than overhauling its core systems.
