Unlike many other enemy extraterrestrial races in science fiction, the Aliens do not have a technological civilization, but are predatory creatures with no higher goals than the propagation of their species and the destruction of lifeforms that could pose a threat. Like wasps or termites, Aliens are eusocial, with a single fertile queen breeding a caste of warriors. The Aliens' biological life cycle involves traumatic implantation of parasitic larvae inside living hosts, which mature before erupting from the host's chest.
