Quarantine Zone: The Last Check Beginner’s Guide

This game throws you in the middle of a Zombie Apocalypse. You are working at a checkpoint as its gatekeeper, tasked with separating the healthy from the infected. Your decision directly affects the fate of your camp. One wrong choice can lead to the doom of your facility. This game blends inspection mechanics with resource management and base defence. You will need to make swift decisions, manage your resources, and protect your base and everyone inside.

How Does the Game Work?

The game requires you to work at the checkpoint and inspect the survivors who want to take refuge at your camp. While checking them, you must use the tools provided to you and decide whether that survivor is Safe or Infected. Depending on your judgment, you can take one of the following actions:

• Approve → Survivor is safe and can join the camp and consume resources.
  
• Quarantine → You are not sure about the survivor, hence you put them on observation with daily checks.
• Liquidation → Immediate execution to protect the camp.

When your work at the checkpost is completed, your task is to develop the camp, install tents with beds, and build infrastructure for the survivors that will be evacuated within a few days. These survivors also consume resources that you need to stock up and manage your inventory, as well as your money.
After a few days of inspection duty, the zombies will attack your checkpoint in waves. You’ll control a drone equipped with a minigun and rocket launcher to eliminate threats before they breach your gates.

How to Distinguish Between Infected and Safe Survivors?

You are provided with various tools to check whether the survivors are infected or not. Your first course of action is visual inspection. During a checkup, look for signs of infection. The visual signs are of four kinds:

• Bite marks: They are the most obvious sign of infection. If you find any bite marks, send them to liquefaction immediately. Survivors will make excuses for the bite mark, saying a dog bit them, and the bite mark might be hidden under clothes. Use your scanner with UV light to reveal hidden wounds.
• Skin conditions: While managing the checkpoint, various types of skin conditions will be found on the survivors. While Freckles and Red skin(looks like sunburn) are safe, if you see a survivor with Green skin, they are infected and need to be liquidated. Whereas, if you find survivors with Pale skin or a skin rash, you should put them in Quarantine and check if other symptoms develop, and then decide their fate.
• Eye Indicators: Survivors with yellow eyes are safe and can be let in. If they have Conjunctivitis, you should put them in Quarantine, and if you see any survivors with Red eyes or eye pus,s then they are infected, and you should deal with them swiftly.
• Nose Spillage: Many survivors may show up at the checkpost with a bloody nose. They are usually safe. But, if you find someone with Nose pus, they are infected and are to be liquidated.

If you ever release an infected into the camp, it’ll spell disaster. If you liquify an uninfected survivor, you lose money, but if you manage to correctly access the infection, you are rewarded, so make your choices carefully.

Inspection Tools

To help with your work, you are provided with various tools to inspect survivors. You start with simple tools, and as you progress, you unlock more of the tools, each with its own use case and purpose. All the tools and their purpose are as follows:

• Scanner: It is the most important tool you have and will work as the first line of defence against the infection. It is used to check for injuries hidden behind clothes. You can also activate its UV light, which can uncover wounds and bite marks not visible to the naked eye.
• Stethoscope: It is used to check the breathing patterns of the survivors. If they have Normal breathing, they are approved to enter. If their breathing is Irregular, you should quarantine them. But if they have Virus breath, which sounds like a wet rattle, they are infected.
• Thermo-pulse-meter: Checks heart rate and temperature. Survivors with high heart rate or temperature must be quarantined, and those with extremely high temperature and pulse are to be executed. 
• Syringe Scanner: When you can’t decide on a survivor’s status from other tools, you can use Syringe Scanners. They are expensive and limited, but give an instant, 100% accurate result.
• Pistol: Use immediately if a survivor becomes aggressive.

Resource and Base Management 

Resource management is also a key part to keep your camp safe. All the survivors you approve to stay will consume resources and take up space in the base. You need to upgrade your base, add new tents, generators, towers, etc. Alongside base upgrades, you must check resources constantly. Lack of resources can lead to the death of survivors or a lapse in the security of your base.

There are three resources in this game:

Fuel powers the generator, which powers automated defenses. Without power, your automated defenses fail during attacks.

Food is required to sustain the survivors. Without food, they will starve.

Medicines are used to maintain the quarantine center. Use them on quarantined survivors during checkups.

Remember that every approved survivor uses up resources. Approving too many refugees without proper planning and resource management will deplete your resources faster. To order your resources, use your tablet’s store menu. It’s best to reorder your supplies when they are around 30% depleted. Bulk orders are expensive; small, frequent top-ups are wiser.

Quarantine Zone Management

Initially, the designated quarantine zone has a limited capacity of four beds. However, the quarantine facility can be upgraded to accommodate additional beds. In fact, it is recommended to increase the capacity of the quarantine zone as soon as possible, as it can create a bottleneck and limit your progress. Whenever you find yourself uncertain if a newly arrived survivor carries an infection during their initial medical screening, you must immediately transfer them to the quarantine zone. All the quarantined survivors must be checked daily. If a patient’s condition begins to worsen, they are likely infected and must be liquidated. Conversely, if they fully recover, they may be safely relocated to the main camp. Crucially, remember to never retain anyone in quarantine for more than two days. If they turn, they will kill the healthy patients nearby.

Additional Tips

• Balance Speed and Caution. Mistakes are costly. It’s better to double-check for subtle signs than to rush. 
• Don’t forget to examine luggage and hidden contraband. Weapons and infected items should be confiscated.
• Monitor Camp Stats. Each day ends with zombie attacks on your base. Keep ammo and defense upgrades in mind.
• Plan Evacuation. Eventually, you’ll evacuate survivors on trucks (often by gender or other criteria). 

Quarantine Zone: The Last Check is a constant test of judgment, efficiency, and restraint. Every survivor you inspect, every resource you allocate, and every second you spend hesitating can determine whether your camp survives another day or collapses from within. Success does not come from acting fast alone, but from acting correctly, trusting your tools, following procedures, and managing growth responsibly. Stay vigilant, keep your quarantine under control, and remember “In a world overrun by the undead, one mistake is all it takes to end everything you are trying to protect.”
