Quarantine Zone The Last Check emphasizes careful observation and decision-making, gradually expanding its mechanics as players progress through the campaign. Early gameplay focuses on basic inspection duties, but after several days, the introduction of daily directives significantly alters how players approach their responsibilities within the quarantine zone.

These directives are accessed through a bulletin board located near the checkpoint entrance. Initially absent to allow players time to learn core mechanics, the board later becomes a daily source of optional objectives. Each posted directive acts as a self-contained side quest, describing a specific threat, outlining inspection priorities, and offering a financial reward upon completion.

Directives are not required to complete the campaign, but they provide valuable income that can be reinvested into equipment upgrades and essential supplies. This makes them especially attractive to players looking to strengthen their position as the difficulty gradually increases.

A standout example occurs on day 13 with the Lemon directive. The directive warns of a survivor who has been using explosive lemons to injure or kill others at another camp. The instructions are strict: any survivor carrying lemons must be eliminated. While the wording may vary slightly depending on language settings, the objective itself is straightforward once understood.

During inspections on day 13, players should focus on baggage checks, as the presence of lemons is the key identifying factor. When a bag filled with lemons is discovered, the survivor should be immediately sent to liquidation. Since their fate is already decided, inspecting them for infection symptoms becomes unnecessary unless the player is attempting to earn additional research points.

Day 13 is also significant because it introduces aggression as a symptom of infection. Players are equipped with a firearm for self-defense, marking the first time violent confrontation becomes a core part of inspections. Aggressive survivors can attack at close range, requiring quick reflexes and awareness to avoid injury.

This combination of high-risk directives and new combat mechanics makes day 13 a turning point in Quarantine Zone The Last Check. It reinforces the importance of prioritization, efficient inspections, and situational awareness.
