Nick Mason comes home from military service to find his city overrun by gang violence. He is recruited into G18, a newly established Counter Gang Division with emergency authority over police, fire, and medical services. Armed with that authority and direct communication with each service, Mason coordinates frontline responses to gang incursions — protecting civilians, containing fires, and pushing back against a city that has been pushed to the brink. A voice-activated command system lets players issue real-time orders to allied units as the chaos escalates.
