The Zone Idle demo opens the first two maps of the Zone, Cordon and Factory, with the hideout, traders, quests, CORTEX automation and operatives that unlock as you level. Red Forest, Labs and Mirage are visible but locked, and prestige is not available in the demo.
Drones have taken the city. You have one drone, a machine gun and a missile lock. Hunt them across 60 missions and six environments, dodging minefields and rooftop turrets, and bring down four boss craft before they bring down you.
