At the end of Quarantine Zone: The Final Check, you are faced with a significant choice that will affect the future greatly. Abandoning the camp or staying on as part of the team will determine how this campaign closes and shape what all participants in the campaign will experience moving forward.
When the Good Ending Unlocks

The campaign will last for a total of 26 days, and on Day 27 you’ll receive a message via radio from Major Rhodes stating that your efforts in fulfilling your assigned duties while serving at the camp have granted you a “good ending.”
The next step is to proceed to the Garage location. Upon entering the Garage you will be presented with a brief cut scene. During the cut scene, Major Rhodes will give you a gold handgun, and explain your possible reassignment. After the cut scene has completed, you will be back in control of your character, and you will have one last chance to choose what you will do.
Choosing to Leave the Camp

At the helipad, if you interact with the helicopter, it will mark the official departure of your character from the camp. This will immediately trigger the end credits and conclude the campaign.
Once you have left, you are no longer able to play as a checkpoint officer. However, the game does create a save file at Day 27, which allows you to return to this point and experience a different outcome if you want to.
The option to return to Day 27 and play as a checkpoint officer is a way for players to feel they have completed their game and are ready to end their gaming experience.
Choosing to Stay at the Camp

If you take a different course through the game by returning to your quarters to sleep instead of getting on the helicopter, this will create an entirely different experience as you will now be experiencing ‘Endless Mode’ from Day 28.
Continuing to stay at the checkpoint will allow players to continue to do inspections, use their golden guns (that they have earned), and complete all tasks that were left incomplete during the regular campaign mode e.g. all of the missed collectible items as well as completing all of the bulletin board related quests. There is no narrative closure for this story, and you can continue to play the game indefinitely.
What You Need to Do to Get the Good Ending

During the course of the campaign there will be an evaluation of your actions. Evacuation decisions, infection control, and zombie management will determine if you can achieve a “good ending”.
In order to remain eligible for a good ending you must successfully manage the evacuations, prevent infected survivors from being found during inspections, and ensure that there is no infection present in the Survivor block. It is also necessary to ensure that you are protecting the camp from zombies, and to contribute to research (by sending zombies in cages) while making evacuations.
Though the game does not provide concrete values regarding threshold levels, the requirements are quite forgiving. When all three evacuation quotas are completed with at least two of those quotas including caged zombies, it’s generally enough. The majority of players were still able to unlock the good ending with failure on one of the quotas, missed cage, and/or breached walls during a zombie wave.
If you continuously kill innocent civilians, admit “infected” survivors or are unsuccessful in meeting your mission objectives, your ability to advance through the game will be negatively impacted and may result in either losing out on or not being able to achieve a “good ending”.
Final Decision: End or Continue
A “good ending” allows you to dictate the outcome of your game’s end. If you choose to leave camp, you will have the opportunity for closure to your storyline. If you decide to stay at the camp, your story will remain somewhat open-ended and there would not be a clear resolution.
Both options, leaving the camp or remaining in the camp, are both valid; it just comes down to your personal preference on which route you wish to take (either to leave, or stay at the camp for an extended period of time).
