Xenomorph Domain Description: A large adult hive-mind overhaul for Stellaris built around the perfect organism. Play the Hive itself — grow the brood from ovomorph to Queen Mother, harvest hosts, subjugate broodstock tributaries, and remake worlds into living resin. Or stand on the other side of the glass: captor empires can contain, study, farm, and profit from the most dangerous species in the galaxy. Military, economy, and exploration stay in a cold biological-horror register
