The helicopter blades chop the air, a deafening countdown to either salvation or oblivion. Your eyes scan the desperate faces, each one a gamble. One wrong choice, one hidden symptom missed, and the hope you’re selling turns to horror. The weight of humanity’s future rests on your shoulders in Quarantine Zone: The Last Check.
Your mission: sift the infected from the uninfected, holding the line against the zombie hordes threatening to consume everything. The game, reminiscent of Papers, Please but with a terrifying undead twist, presents you with choices that decide the fate of the human race. Here’s what I’ve learned about securing each ending in The Last Check.
The Tightrope of Survival
It’s like working security at the world’s worst airport. The Campaign spans 26 tense days. Success means extraction by helicopter, while failure consigns you to the endless, grinding challenge of Checkpoint Alpha. Your aim is simple: evacuate the healthy and give humanity a fighting chance. But upgrading the Survivor Block, preventing deaths within its walls, and developing reliable diagnostic methods are all part of a complex equation where a single misstep can tip the scales toward disaster.
Here’s how to navigate the complexities of this medical sim.
Good Ending – “Good Work, Son”

At Checkpoint Alpha, your uninfected survivors are your lifeline. Your inspections must be meticulous. Infected individuals go to liquidation or the Laboratory for analysis; those showing signs of illness are Quarantined for further observation; and the seemingly healthy are admitted to the Survivor Block. You will inadvertently allow an infected person to slip through, but swift Quarantine action can isolate them before they transform.
The key to success is hitting your Evacuation Quotas. These mandatory evacuations happen at the end of days 5, 10, 15, 21, and 26. While perfect execution isn’t mandatory, completing at least four out of five quotas significantly improves your chances of a positive outcome. Here’s what each quota demands:
- Day 5 – Five uninfected.
- Day 10 – Nine uninfected and zombie cage.
- Day 15 – 14 uninfected and zombie cage.
- Day 21 – 17 uninfected and zombie cage.
- Day 26 – 18 uninfected and zombie cage.
Remember, the quota tallies Non-Infected individuals sent via the Science and Military Trucks. An infected survivor counts against your progress. Always send a few extra survivors to offset any potential miscalculations.
How do you get a zombie in the cage in Quarantine Zone: The Last Check?
A zombie cage becomes relevant starting on Day 10 with the “Hi Doggy” side quest. You’ll need a zombie secured within the cage for four out of five evacuations. Manually move a zombie from Quarantine; you can only move one at a time. A yellow dot beside the cage icon in the top-left corner indicates successful containment. Keep the zombie fed with one corpse per day.

Consistently maintain zero deaths inside the Survivor Block. Only admit individuals cleared of infection and contraband. Keeping survivors alive ties directly into The Last Check‘s Task system, so complete quests as they arise.
Bad Ending – SNAFU
Ever watched a house of cards collapse? The bad ending is like that, only much, much worse. It’s the accumulation of errors, missed opportunities, and outright failures.

The bad ending is earned, not stumbled upon. If the Quarantine Zone Wall falls during zombie attacks (defended by your drone) or you consistently ignore/fail Tasks, the odds of a grim finale increase dramatically.
What happens if you miss evacuation quotas in Quarantine Zone: The Last Check?
Missing three or more Evacuation Quotas is a near-guarantee of the bad ending. Even if you meet the uninfected quota, failing to provide a zombie in the cage for four or five evacuations results in failure. Mislabeled patients, healthy survivors sent to liquidation, or infected individuals admitted to the Survivor Block…these all contribute to a disastrous outcome.
The game is a mirror, reflecting the choices you make. Are you building a fortress of hope, or a monument to failure?
