How to Actually Save Humanity in Quarantine Zone: The Last Check (good ending guide)
The fate of the human race rests entirely on my ability to fill out paperwork correctly and keep a pet zombie well-fed.
Moving from the tutorial to the main Campaign is a slap in the face. You have twenty-six days to prove you aren't incompetent, and the game doesn't make it easy. Quarantine Zone: The Last Check pulls a Papers, Please by forcing you to balance morality with cold, hard bureaucracy. There are two distinct ways this story wraps up: the "Good" ending where you get a pat on the back from the brass, and the "Bad" ending where everything goes to hell.
Getting the good outcome isn't just about surviving. It requires hitting specific, escalating milestones that feel impossible when you’re running low on fuel and patience. I’ve broken down exactly what you need to do to get the "Good Work, Son" achievement and how to avoid the dreaded "SNAFU."
The Good Ending: "Good Work, Son"
To get the golden ending, you need to understand that your primary mission isn't just "don't die." It is about evacuation. You need to consistently send healthy, uninfected people out via the transport trucks to give humanity a fighting chance.
The campaign throws five specific Evacuation Quotas at you. These are scripted deadlines that hit on Days 5, 10, 15, 21, and 26. You don't need to be perfect, but you do need to hit at least four out of five of these quotas to secure the good ending.
The Quota Breakdown
Here is exactly what the game demands from you on those deadline days:
Day 5: 5 Uninfected evacuated.
Day 10: 9 Uninfected evacuated + Active Zombie Cage.
Day 15: 14 Uninfected evacuated + Active Zombie Cage.
Day 21: 17 Uninfected evacuated + Active Zombie Cage.
Day 26: 18 Uninfected evacuated + Active Zombie Cage.
The trick here is that the game counts Non-Infected survivors. If you accidentally sneak an infected person onto the truck, they don't count toward your total (and you might doom the convoy). I always try to send two or three extra people just to be safe. It acts as a buffer in case one of my "healthy" evacuees turns out to be hiding a bite mark I missed.
The Zombie Cage Requirement
Starting on Day 10, the "Hi Doggy" questline introduces the Zombie Cage mechanic. This isn't optional. For every evacuation from Day 10 onwards, you must have a live zombie contained in the cage.
You have to manually drag a turned survivor from the Quarantine block into the cage. Look for the yellow dot next to the cage icon in the top-left of your HUD. If that dot is yellow, you are good to go. Just remember to feed the thing one corpse a day. If it starves, you fail the quota. If you forget to load it, you fail the quota.
The Bad Ending: "SNAFU"
Getting the bad ending is surprisingly easy. You basically just have to be bad at your job. This ending triggers if you fail three or more of the Evacuation Quotas.
How to Fail
The fastest way to trigger the "SNAFU" ending is to neglect the Zombie Cage. Even if you send fifty healthy people on Day 21, if that cage is empty, the game marks it as a failed quota.
You can also trigger a game-over state (which leads to failure) by letting the Checkpoint Wall fall during the nightly defense segments. If the infected breach the perimeter because you forgot to upgrade your drone or ran out of ammo, it’s over. Neglecting the survivor tasks on the bulletin board or letting too many people die inside the Survivor Block will also push you toward this grim conclusion.
Basically, if you want the good ending, treat your uninfected survivors like precious cargo and your pet zombie like a VIP. Everyone else? Well, that’s what the liquidation chamber is for.
