Use high-tech tools to uncover signs of infection among the terrified survivors. Identify contraband, forbidden items, and even rare collectables as you work to keep your checkpoint secure. Send those with suspicious symptoms to quarantine for observation, to the lab for additional screening, or save healthy survivors by sending them to the living block. And those who show to be infected… well, they don’t stand a chance anyway. As the survivor population swells, you’ll be relied upon to provide essentials such as power, food, and medicine. When the alarms are raised, pilot armed drones to ensure the infected don’t breach the compound. The better you manage your ever-expanding base, the more resources, tools, and weapon upgrades you’ll unlock.
