However, the Combine appears to have a limited grasp of local teleportation. Through this technology, the Combine can traverse entire universes and dimensions in their conquests. The Combine is incredibly advanced technologically, being able to teleport to an entirely different plane of reality. Following standard Combine procedure, Earth's dominant species were modified to form a new arm of the Combine military, and the planet's resources were systematically stripped. įollowing the Black Mesa Incident and subsequent Seven Hour War, Earth became the Combine's most recent (known) annexation. It brought with it members of several species, both its allies and its slaves, including the Vortigaunts. It is known that the Combine invaded the homeworld of the Nihilanth's species and inflicted a total genocide against them, with only the Nihilanth able to escape the onslaught by seeking refuge in Xen. It is unknown exactly how many worlds the Combine has under its control, but being an extradimensional empire, they most definitely possess a great number of universes and dimensions. Breen refers to the Combine Soldiers and Civil Protection as "The Transhuman Arm of the Combine Overwatch" in Nova Prospekt, implying that "Combine" is an accepted name of the empire, even by the Combine itself. The name is pronounced COM-bine, as in Combine harvester, opposed to the verb form com-BINE, as in "to join together or unite." Dr. Judging by dialogue from Breen, many of the territories under control by the Combine are nigh-uninhabitable by humans without life support systems.

Equally dire is the threat of "permanent off-world relocation" directed towards normal citizens for disobedience or disruption to the Combine regime. They are also highly trained, and can adapt well beyond the confines of Earth, in other universes and dimensions if needed - in-game dialogue mentions potential deployment of Overwatch units across the Combine Empire in a "permanent off-world assignment." Assignment on other worlds is considered a terrible fate for Overwatch soldiers unfortunate enough to be stuck with it, and is often threatened as a punishment for soldiers who fail in their duties. Overwatch Soldiers have been surgically altered to be overall much deadlier and more resilient than normal human beings. On Earth, the Combine notably uses their technology to create armies of cybernetically-enhanced transhuman soldiers forcibly conscripted from the enslaved human population, comprising the bulk of the Earth-based Combine Overwatch - a highly mobile and adaptive military force that can respond to any threat and crush any opposition. The results of the Combine's re-engineering process are " synths" - synthetic organisms augmented with Combine technology that serve a variety of functions within the empire, from weapons of war to mindless worker drones. They seem to only assimilate intelligent species from the worlds they conquer, and manipulate these species through many means, including bioengineering and invasive surgery, as well as artificial implantation, incorporating them into the Combine. The Combine is composed of an untold number of species, with entire alien ecosystems under its dominion. Wallace Breen, a puppet who serves as the appointed 'Administrator' and humanity's representative to the Combine. On Earth, beings called the Advisors are responsible for overseeing all communication and interaction between the Combine and the Earthly occupation, as well as ruling all Combine forces on earth through Dr. Little is known about the Combine's ultimate goals beyond imperialistically enslaving and subjugating worlds, but it can be assumed its main ambition is to assimilate all life across the Multiverse.ĭetails of the Combine's leadership and administrative structure remain unknown, as do whether they consist of an economy, system of governance or even a society that exists within the limits of human comprehension. The Combine is an unfathomably massive alien empire spanning countless parallel universes and dimensions, comprised of an unknown (but presumably vast) number of allied and enslaved species.
