Post-outbreak simulation Quarantine Zone: The Last Check casts players as high-security checkpoint border control officers. You must check approaching migrants, assess their risk, and make quick judgements to let them through or send them away between civilisation and chaos.
Quarantine Zone: The Last Check is on observation and inspection. Players use heat scanners, UV lights, and blood testing equipment to detect migrants. Some have evident symptoms, while others disguise them or provide fake documents. You must spot lies, diseases, and anomalies quickly. Later in the game, illnesses grow harder to identify and equipment becomes scarce, making decisions harder.
Pressure rises with each shift. You have a limited amount of test kits, time to process the queue, and escalating priorities like report processing and defensive system upgrades. Allowing a carrier may produce a breach, while incorrectly rejecting or eliminating an innocent person can provoke unrest. Longevity makes it harder to distinguish unwell from healthy.
