Quarantine Zone: The Last Check is a mixture of Papers Please and Contraband Police. Your task is to check for infections and take appropriate action on every survivor so that you avoid spreading the infection further. Our Quarantine Zone: The Last Check beginner's guide will show you how to become more the best at your job.
How to Use Tools

As you progress through the game, you will be given new tools to check the survivors. Most of them won't have any visible infection. You have to use the tools to see if everything checks out or if the person is hiding something.
Using these tools will allow you to either figure out if the person is healthy, infected, or about to turn into a zombie. If they have an injury, you should put them in the quarantine zone and see if they're condition improves or not.
Tool | Purpose |
---|---|
Scanner | Used to scan the person for bite marks or other injuries. You can use the UV light with it to see hidden infections as well. |
Stethoscope | Used to check the breathing pattern of people to see if they are normal or have an infection/virus. |
Thermo-Pulse-Meter | This tool checks a person's temperature and pulse. A higher pulse/temperature means the person should be put in quarantine. |
Pistol | Some survivors might attack you due to being aggressive. This is usually due to a virus, so don't be hesitant to take them down. |
Syringe Scanner | Using this scanner on someone will instantly tell you if they are infected or not. However, the materials needed are expensive, so only use the syringe if you are not sure about the person. |
How to Spot Infections

The main job of your character is to find infected people and either put them in quarantine or send them to the liquidation zone. Different symptoms will affect people, some might be the sign of the virus, while others aren't. They will try to hide everything from you, but your job is to use your tools and take action.
As you progress, new types of symptoms will pop up, and you'll have to know what to do. Sometimes, it can take trial and error, but we're to help you. Here's every symptom that can be affecting a human, as well as every action you need to do in case they are carrying something, etc.

What is the Quarantine Area

Your job is to check every person and send them to the right area. If there is something wrong with the person, you have to put them in quarantine. Initially, the quarantine area can hold up to 4 people, but you can upgrade this later in the game.
After sending someone to the quarantine zone, wait a day and check up on them to see if they're health has improved or not. Some people will show an improvement and have their cough or other infections healed. However, if the person's health shows signs of degradation, you should do the right thing and send them to the liquidation zone - don't ask what happens there.
Keep in mind that if you leave a person in quarantine for more than 2 days and they turn out to be infected, they will turn into a zombie and bite all other people in the quarantine area, so you're risking innocent lives. Make sure to check in on time and clean up the area before sending new people there.
How to Upgrade Your Base

Upgrading your base is one of the most important things you can do. As you progress, your base will get attacked by hordes of zombies. Initially, you can mow them down with the mini-gun and the rocket launcher. However, zombies will become stronger the more you play.
To continue keeping them out of your base, you'll have to upgrade all your weapons so that they deal more damage. This will also increase their reload speed, which means you have more damage output.
If you want to upgrade your base, open your tablet and head over to the "upgrade" section. Here, you can find everything you want to upgrade, so prioritize what you want to enhance first and do it. You can even upgrade your tools to make them more effective as well.
How to Defend Your Base

Defending your base is as important as keeping it safe from the inside. After a few days, hordes of zombies will attack your camp and try to break down the gates. Your job is to protect everyone and use the drone to clear out the horde.
When you are being attacked, you will automatically use the drone. There, you have the option to use the mini-gun or rockets. You should regularly upgrade these weapons as stronger zombies will be harder to kill later in the game. If you cannot defend your base, it will be game over, and you'll have to start from the previous checkpoint again.
When to Buy More Resources

Buying resources is extremely important in Quarantine Zone: The Last Check. Every survivor that you clear will be sent to the evacuation zone. Here, they will stay in tents and eat in the dining hall. The more people you have, the more resources they will spend.
If they run out of resources, there will be turmoil in your camp, and the people might even riot. To avoid all that, you should always check how many resources are being used by heading over to each block. If the generator is about to turn off, you should get more fuel and place it near the generator.
You should also keep an eye on the food to see if you have to get more or not. Ordering resources can be done by opening your tablet and purchasing food, fuel, and medkits. Buying them in bulk can cost you a lot of money, so make sure that you regularly purchase resources and keep your camp running.
