When a survivor goes through the checkpoint in Quarantine Zone: The Last Checkplayers must analyze their condition to see if they are in a good condition to be cleared and stay at the camp until evacuation. But that's not always the case, and many times they have to decide what to do with survivors who are in poor or questionable condition.
How to Deal with Skeleton Survivors in Quarantine Zone The Final Check
Players will encounter a strange survivor early in the Quarantine Zone: The Last Check campaign – here's how to deal with them.
This guide tells players what they need to know about each distribution zone in Quarantine Zone: The Last Checkpoint so they can easily decide where to send each survivor based on their symptoms.
All Distribution Facilities in Quarantine Zone: The Last Checkpoint
Where should you send every survivor in Quarantine Zone: The Last Checkpoint?
There are four distribution zones i Quarantine Zone: The Last Checkpointand each is suitable for a specific type of survivor.
Surviving block
Players must check each survivor for symptoms using all the tools at their disposal, as symptoms can sometimes be hidden beneath the surface. If they have no symptoms, they should go ahead and send them to the Survivor Block.
Conditions in the apocalypse are dire, and naturally survivors will exhibit signs of illness not directly related to infection. These symptoms will be marked as green on the symptom chart and associated with being sick rather than being infected. In that case, players can also safely put them in the block.
The survival block is one of the most important areas within Quarantine zoneas this is where the players wait for the evacuation to begin. Players will want to bring in as many healthy survivors as possible so they can reach their quota and provide plenty of manpower for the military and science truck, giving them useful rewards such as money, research points, and spray analyzers.
Initially, the Survivor Block will only be able to hold a maximum of 12 survivors, but players can increase its capacity by upgrading it. It can hold up to 25 people, but players must reach zone level V, and they must accumulate over $16,000.
Liquidation
While sick and asymptomatic survivors are sent to Survivor Block to safely await evacuation, infected survivors are sent to Liquidation to be eliminated.
When players examine a survivor and see that they have symptoms in the red area, they are considered infected and must be terminated immediately. This is when players must send them to the liquidation block.

If they are sent to the Survivor Block, they can become infected and kill others, or they can be sent to the Major on evacuation day, jeopardizing the mission and putting the player's job and life at risk. If quarantined, they will eventually turn and kill the other survivors being monitored, without giving them a chance to be re-examined and perhaps live.
In some cases, players must send apparently healthy survivors to Liquidation, as they may be wanted by the Major. Players should check the bulletin board daily for quests, and if any survivors are requested to terminate, they must send them to Liquidation, even if they are not infected.
Quarantine
Quarantine is a place where players can temporarily isolate survivors before truly deciding their fate. At the checkpoint, players will encounter many survivors who have symptoms that could mean they are infected or simply sick – these symptoms are highlighted in orange. But if they don't have any obvious signs of infection, they won't want to liquidate them if it's just a treatable disease.
If they develop other more serious symptoms or actually turn, the risk of infecting or killing other survivors is not as high and can be more easily stopped, since they are stuck in a small room with fewer or no survivors. It's better to be safe than sorry, so if the tools players have on hand can't give them a full diagnosis, they should quarantine them for a day or two.
When players wake up the next day, they can return to the Quarantine Zone and re-examine the survivors to see if their symptoms have resolved or progressed to something more serious. If this happens, they can send them to Survivor Block or Liquidation. When the worst happens, meaning a survivor turns into a zombie, players must pull the Clear lever to burn the infected and any deceased if they were there with other survivors. Alternatively, they can also be sent to a cage for testing before the room is sanitized.
Initially, the Quarantine will only be able to house a maximum of three survivors, so it can fill up pretty quickly. Thankfully, players can upgrade it in build mode, and it will be able to hold up to seven survivors. To fully upgrade the quarantine building, players need $13,500, and they must reach zone level V. They must be careful though, as a high capacity quarantine area also means more survivors will die if an infected survivor turns over overnight.
There is the case of survivors with muscle problems. While reacting aggressively to being hit with the reflex hammer can be a sign of illness or infection, some players have other illnesses that prevent them from controlling their reflexes.
When players notice that a survivor has a slack jaw and is exhibiting problems with their reflexes, they should look for other signs of infection. But if their only problem is their reflex, they should be sent to the Survivor Block, because they only have problems with muscle reflexes.
Laboratory
The lab will not be available until after the first evacuation, as players must first familiarize themselves with the other distribution facilities. This is a more complex build, but it is very important, as it allows players to find new symptoms and understand the virus better.
When players encounter an unknown symptom while examining a survivor, they should send them to the laboratory regardless of whether they are apparently healthy, diseased, or infected. A guard arrives to pick up the survivors and escort them to the lab. Here, players must use the computer to extract the target organ, place it in the sample creator, and then analyze it for symptoms. The procedure will kill the survivor, but it will allow players to discover a new symptom that will allow them to better examine survivors and determine their status.
Additionally, players can send quarantined survivors to the laboratory cage. They must be fed one corpse daily, and then on evacuation day they will automatically be loaded onto a truck, and players will receive a $2,000 reward for keeping them alive.
It costs $40,000 for the first Laboratory upgrade, and this is where players will unlock the Zombie Cage. Then, when they reach Zone Level III, they can pay $10,000 to get an automatic feeder that keeps the zombie alive.
