The Combine (“alien” occupied government) installs a device called the suppression field which stops all human reproductive activity by “limiting certain protein chains.” (You know what might be) They also put chemicals in the water (fluoride) to dumb the population down, as well as turn rebels into trans humanist husk (WEF Internet of things). The main controllers of the combine (or so it seems) are alien life forms with no visible feature other than being “grub-like” entities (in our world these are “demonic” entities or perhaps just elements of the elites subconscious they take drugs to commune with), however the combine mostly controls earth through human subordinates (Rothschilds, Rockefellers, Soros)

Also interestingly enough the combine, though they are capable of traveling to other universes through quantum tunneling, they are incapable of traveling within the same universe over long distances, so they are dependent on human technology like trains. This technological limitation is what makes the Half Life series fascinating, and is also the concern of the Portal series

Earth surrendered to the combine on behalf of the United Nations (blue beam)

How'd you discover that?

Being familiar with many conspiracies, listening to infowars, knowing the WEFs plans, playing half life and other FPS games, paying attention to patterns/overlaps.
