Citizens

 are the oppressed human residents of the Combine's remaining urban centres.

With hardly any rights afforded to them, they are often moved without warning between cities, either to disrupt the formation of organised resistance groups or prevent citizens from becoming comfortable with their surroundings.

Documented Civic Deeds
In City, a citizen's social value is tallied by Documented Civic Deeds(DCD). These are earned through actions that contribute to the continued stability of the city, such as reporting threats to Civil Protection.

Workforce members can earn Documented Civic Deeds through gainful employment by attending daily work-shifts or seeking temporary work as Infestation Control.
