Combine 

1.The Combine is a fictional powerful alien race and empire from the first-person shooter computer game Half-Life 2. During the game, it is also referred to as the Universal Union, and as "our benefactors" in propaganda.
2.The Combine is a vast empire spanning multiple parallel universes. The empire is inhabited by an unknown number of sapient species, and appears to be governed by a race of bizarre, artificially evolved Advisors. The Combine expands its empire by invading worlds and enslaving the dominant species to be exploited as it sees fit. By manipulating these inhabitants through methods including bioengineering and implantation, the Combine creates a race of super-soldiers uniquely adapted for the environment of that particular world. This process results in a highly mobile and adaptive military force which is able to respond to any threat and crush any opposition. The reasons behind the Combine's imperialism remain unknown throughout the game.
3.The Combine Advisors are the face of the Combine Empire, suggesting that they are probably the original master race behind the alien empire.
4.The primary military force of the Combine on Earth is the humanoid Combine Overwatch (referred to by Doctor Breen as the "Transhuman arm of the Combine Overwatch"): humans who have been modified into "transhuman" (or "post-human", as referred to by Dr. Kleiner) cyborgs. They are the most frequently encountered foes throughout Half-Life 2. This could also be another possible reason why they are called the Combine, because they are a "combination" of humans and alien technology.

The Combine are an alien race.

combine 

1. A piece of farm equipment that harvests grain/corn/etc. The whole plant is cut down and the kernels are removed. The kernels are then stored in a tank, while other material, such as stalks, is deposited on the ground.
2. A metaphor used by Chief Bromdon in Kesey's One Flew Over the Cuckoo's Nest to describe the shaping influences in America. Media, government, authority figures, the social class system, citizens, greed, etc. shape members of American society; any individuals are chewed up until they are left naive and docile - certain qualities are kept, just like a combine in the field.

1. The combine erased the field of grain, leaving only straw on the ground and kernels in its storage tank.

2. The combine is a cause of the disapproval of American society from foreign perspectives.
