The Combine, abbreviated as CMB and referred to as "Our Benefactors" in propaganda, is the title of an immense and powerful inter-dimensional organisation, composed of a massive variety or both allied and enslaved species. It is the Primary Antagonistic Force in the game Half Life 2. The goal of the Combine is to build a massive inter-dimensional empire known as the Universal Union and dominate the Half-Life Multiverse.
The Combine Empire sprawls across countless parallel universes and is composed of an unknown, but likely massive, amount of sentient species. The leaders of The Combine Empire still remains anonymous but it is clear that the an alien species called The Advisors are the ones responsible for maintaining control over the Earth. The Combine military is filled with a massive amount of bio engineered alien species, known as Synths. This essentially lead to the creation of an army Super-Soldiers, a highly mobile and effective military force to be reckon with, able to adapt in almost every environment throughout the Multiverse.
The Combine has also access to extremely advanced teleportation technologies. They are able to expand their empire throughout the the Multiverse by teleporting their forces to any desired Universe they want to gain control of. At some point, the Combine discovered a series of portal storms on the human home world Earth, and in response to this, they came to the Earth, destroyed the entire Earth military force in mere hours and conquered the Universe the Earth was in. However, Gordon Freeman, along with the Resistance, were able to push back the Combine, destroyed their main Base of operations on Earth, The Citadel, and successfully driven the Combine off the Earth and the remaining Combine forces on Earth are force to retreat and are trying to call for reinforcements.
