Colony

Bears a lot of resemblance to the video game series Half Life 2 (2005). There are never-seen alien overseers, with co-opted humans who act as a militaristic police force and proxy governers. A resistance in the oppressed population with sympathizers, as well as those who wish they wouldn't interfere. Furthermore there are large alien structures and walls that create blocks to section off populated areas, with drones that observe the civilian population and can inform the authorities. There are also work camps and prison complexes used as torture facilities.
