Managing a zombie outbreak checkpoint tests your inspection skills and moral compass. Quarantine Zone: The Last Check challenges you with 25 achievements that track everything from basic survival milestones to bizarre hidden objectives. You'll need multiple playthroughs, careful resource management, and willingness to experiment with unconventional actions to reach 100% completion.
This guide breaks down every achievement requirement with specific unlock conditions and practical strategies. Whether you're hunting evacuation quotas or attempting to score a brain through a basketball hoop, you'll find exactly what you need to check off each objective.
What Achievement Categories Exist in Quarantine Zone?
The game organizes its 25 achievements into five distinct categories that reward different aspects of checkpoint management.
Story progression achievements mark your journey through daily operations and major milestones. These unlock naturally as you survive shifts and meet evacuation targets. Inspection and tool achievements reward mastery of detection systems and laboratory research. Combat and interaction achievements focus on physical confrontations and unique item handling. Ending achievements require specific quota performance across full playthroughs. Secret achievements hide quirky objectives that demand exploration beyond routine tasks.
Understanding these categories helps you plan which achievements to target during specific runs. Some unlock automatically through normal play, while others need deliberate focus.
Tip
Track your progress through Steam's achievement overlay. Several objectives require cumulative actions across multiple sessions, so monitoring totals prevents wasted effort.

How Do You Unlock Core Progression Achievements?
Basic survival and facility management achievements form the foundation of your completion journey.
First Time, Huh? unlocks when you complete your first shift without dying. Focus on learning inspection basics and avoiding aggressive survivor confrontations. Evacuator requires hitting a single evacuation quota, typically on Day 5. Master Evacuator demands perfect quota performance across all five checkpoints in one playthrough (Days 5, 10, 15, 21, and 26).
Jackpot! needs $50,000 total earnings. Save aggressively by minimizing fuel purchases and avoiding unnecessary tool upgrades early. Confiscated contraband sells for significant profit. City Builder unlocks when you upgrade any building in the survivors block through your tablet interface. Choose upgrades that improve inspection efficiency or survivor morale.
Tooling Up triggers when you purchase your first inspection tool. Prioritize the X-Ray Scanner for detecting internal contraband, as it enables multiple other achievements.
Which Achievements Require Perfect Inspections?
Inspection accuracy achievements demand meticulous attention during survivor processing.
Perfect Day requires flawless inspections on every survivor during a single shift. Use all available tools systematically. Check eyes for discoloration, scan for internal contraband with the X-Ray, and verify documentation thoroughly. Miss one detail and you'll need to retry the entire day.
Yeah! Science! B...aby! unlocks when you research your first symptom in the laboratory. Collect biological samples during inspections and submit them through your tablet. Research unlocks new detection capabilities for future shifts.
Finders Keepers triggers when you confiscate any contraband item. Under My Skin specifically requires confiscating internally hidden contraband, which only appears when using the X-Ray Scanner. Can't Touch This needs you to confiscate a zombie body part from a survivor, a rare occurrence that typically happens after failed quarantine procedures.
Warning
Perfect Day resets if you approve an infected survivor or reject a clean one. Save tool usage for uncertain cases rather than rushing through inspections.

What Are the Combat and Interaction Achievement Requirements?
Physical confrontations and unusual actions unlock several hidden achievements.
Ain't That a Kick? requires knocking out a survivor using the medical hammer. Wait for an aggressive survivor to threaten you, then strike them with the hammer instead of calling security. Watch Them Closely From Now On takes this further by requiring you to eliminate a survivor who physically attacked you.
Light My Fire unlocks when you cleanse a quarantine cell using the flamethrower button for the first time. This occurs during standard infection containment procedures. Dinner Is Served needs you to feed a corpse to the zombie in the cage. Drag a body to the cage area and interact with the feeding mechanism.
Janitor and Rat Slayer track rodent elimination. Kill one rat for Janitor, thirty for Rat Slayer. Rats spawn randomly throughout the facility. Use your sidearm to shoot them when they appear near equipment or storage areas.
How Do You Unlock Both Ending Achievements?
Ending achievements require separate playthroughs with different quota performance.
Good Work, Son demands hitting at least four of five evacuation quotas while maintaining the zombie cage properly. Focus on accurate inspections, aggressive contraband confiscation for funds, and steady survivor processing. Our Quarantine Zone: The Last Check Endings Guide covers detailed strategies for reaching the positive outcome.
SNAFU unlocks through the bad ending. Deliberately fail quotas by rejecting too many clean survivors or approving infected individuals. Alternatively, neglect wall maintenance until the facility falls. This ending requires intentionally poor performance.
You cannot unlock both endings in one playthrough. Plan for at least two complete runs to achieve full completion.
Important
Save your good ending run for last. The bad ending requires deliberate failure, making it easier to achieve quickly once you understand game mechanics.

What Are the Secret and Miscellaneous Achievement Strategies?
Hidden achievements reward experimentation and attention to environmental details.
Brain Slam stands out as the strangest objective. You need to shoot a human brain through the basketball hoop in the facility. Brains appear as confiscated contraband or laboratory samples. Grab one, locate the hoop near the recreation area, and make the shot. Clean throws count, bounces don't.
Safety First requires using an inspection tool on a checkpoint staff member. Target a colleague with your X-Ray Scanner or other equipment during downtime. I Can Read unlocks when you complete any task from the bulletin board. Check the board regularly for contract targets and special requests.
Headhunter needs you to eliminate a contract target listed on the bulletin board. Accept the contract, identify the target during inspections, and handle them according to the contract terms. Certified Next Shouter tracks 100 uses of the "Next" command. This unlocks naturally through normal gameplay as you process survivors.
Lights Out requires shooting five light bulbs in the facility. Use your sidearm to target overhead lights in various rooms. Bulbs break permanently when shot.
Which Achievements Should You Prioritize First?
Strategic achievement hunting saves time across multiple playthroughs.
Target Master Evacuator and Good Work, Son together during your first serious run. These require similar careful play and quota focus. Combine this with Perfect Day attempts on easier shifts when survivor volume stays manageable.
Save SNAFU for a quick second playthrough where you deliberately fail. Knock out the rat achievements gradually across all runs since rats spawn unpredictably. Focus Brain Slam and other secret achievements during your good ending run when you have stable resources and time to explore.
Jackpot! accumulates naturally if you confiscate contraband aggressively and avoid overspending on fuel. Don't rush tool purchases beyond essential X-Ray and documentation checkers.

What Common Achievement Mistakes Should You Avoid?
Several achievements fail due to preventable errors.
Perfect Day breaks if you process survivors too quickly without thorough checks. Slow down and verify every detail systematically. Master Evacuator requires hitting all five quotas in sequence. Missing even one forces a complete restart.
Brain Slam fails if you incinerate the brain before attempting the shot. Always check your inventory before destroying confiscated items. Under My Skin needs the X-Ray Scanner, which some players skip to save money. Invest in essential tools early.
Players often miss I Can Read by ignoring the bulletin board entirely. Check it daily for new tasks and contracts. Headhunter requires accepting the contract before identifying the target. Read board postings carefully.
Achievement tracking persists across saves, so cumulative objectives like Certified Next Shouter and Rat Slayer continue progressing even after failed runs. Don't restart unnecessarily when hunting these specific unlocks.
