Quarantine Zone The Last Check draws clear inspiration from the inspection-driven gameplay of Papers, Please, but reimagines the formula within a zombie apocalypse setting. Players take on the role of a quarantine zone officer responsible for maintaining order, identifying infection risks, and ensuring that both staff and survivors remain alive long enough to be evacuated from the danger zone.

At the core of the gameplay is survivor inspection. Players are equipped with a set of tools designed to detect signs of infection, including a thermometer to identify abnormal body temperatures and a scanner used to locate bite marks or scratches. These tools form the foundation of daily operations, as players must decide who is safe to enter the quarantine zone and who must be removed before they become a threat.

After the first few in-game days, Quarantine Zone The Last Check gradually introduces additional systems through daily directives. These directives appear on a bulletin board located at the checkpoint entrance and function as optional side objectives. The delayed introduction allows players to become familiar with basic inspection mechanics before being tasked with more complex decisions.

Each directive provides contextual information about a specific situation, outlining what players should look for among incoming survivors, how to handle the identified threat or item, and the monetary reward for successful completion. While directives are not mandatory for story progression, they offer a reliable way to earn additional funds, which can be used for supplies and upgrades critical to long-term survival.

One of the most notable examples is the directive issued on day 13, commonly referred to as the Lemon directive. This directive describes a survivor responsible for using explosive lemons to harm others in another camp. The instructions are clear: if a survivor is found carrying even a single lemon, they must be eliminated immediately. During inspections, players must pay close attention to survivor baggage, as a bag filled with lemons identifies the target.

Since the directive explicitly orders liquidation, players can prioritize baggage inspection before checking for infection symptoms. This approach saves time, as symptom detection becomes irrelevant once the lemons are found, unless the player is aiming for additional research points through a flawless inspection.

Day 13 also introduces aggression as a recognized symptom of infection. On this day, players receive a firearm from Georgie for self-defense, preparing them for hostile encounters during inspections. Aggressive behavior can manifest early, and players must react quickly due to the close proximity between officer and survivor. This combination of new mechanics and high-risk directives highlights the game’s increasing complexity.
