Welcome to the most unforgiving job in the apocalypse. You're standing at humanity's last line of defense, where one wrong decision means death for everyone behind you. Quarantine Zone: The Last Check throws you into the role of a checkpoint gatekeeper, tasked with separating the healthy from the infected. Every survivor who approaches your station is a potential threat. You'll need sharp eyes, steady hands, and the stomach to make impossible choices when resources run dry and the horde closes in.
What Makes This Game Different?
Think Papers Please meets zombie survival horror. You're not running through abandoned streets shooting infected. Instead, you're conducting medical inspections, managing limited supplies, and dealing with the moral weight of sending potentially healthy people to their deaths because you can't risk being wrong. The game combines inspection mechanics with tower defense segments where you'll protect your base from waves of infected using automated defenses and firearms.
Your checkpoint becomes a living organism that needs constant attention. Survivors you approve join your camp, consuming food and fuel. Send too many through and your resources deplete. Reject too many and you'll face riots from desperate people who have nowhere else to go.
How to Spot Infected Survivors
Visual inspection is your first defense. When someone approaches your checkpoint, you need to scan them quickly for telltale signs of infection. Here's what separates the living from the almost-dead:
Skin conditions tell you everything. Pale skin means quarantine them immediately for observation. Green-tinted skin? They're hours from turning. Red skin is actually harmless, just stress or sunburn. You'll learn to spot the difference between freckles (safe) and skin rash (quarantine candidate) in seconds.
Eye symptoms are critical indicators. Yellow eyes pass inspection without issue. Conjunctivitis requires quarantine and a follow-up check the next day. Red eyes signal imminent transformation into a zombie. When you see that crimson glow, you know what needs to happen.
Warning
Eye pus and nose pus both indicate active infection. These survivors will turn within hours. Don't hesitate.
Infection symptom detection
Bite marks are the most obvious sign, but survivors will hide them under clothing or bandages. Use your scanner with UV light to reveal hidden wounds. A single bite mark means immediate liquidation. No exceptions, no second chances.
Useful Tools and When to Use Them
You start with basic inspection tools and unlock more as you progress. Each tool serves a specific purpose, and knowing when to deploy them saves precious time and resources.
The scanner is your workhorse. Point it at survivors to check for visible injuries, then activate the UV light mode to reveal hidden bite marks or infections that aren't visible to the naked eye. Survivors will lie, but the scanner doesn't.
Your stethoscope checks breathing patterns. Normal breathing clears them for entry. Irregular patterns mean quarantine. Virus breath is the sound of death approaching, a wet, rattling noise that means they're beyond saving.
The thermo-pulse-meter measures temperature and heart rate simultaneously. Elevated readings (slightly high temperature or pulse) warrant quarantine. Extreme readings mean they're infected and dangerous.
Tip
Save your syringe scanner for ambiguous cases. The materials are expensive, but one scan instantly reveals infection status. Use it when other tools give conflicting signals.

Managing Your Quarantine Zone
Your quarantine area starts with four beds. This is where you send survivors showing early infection signs or ambiguous symptoms. The quarantine system is your safety net, but it's also a ticking time bomb.
After sending someone to quarantine, you must check on them within 24 hours. Some will improve, their cough clearing up or fever breaking. Others will deteriorate. If someone shows degradation after a day, send them to liquidation immediately.
Here's the critical mistake beginners make: leaving infected people in quarantine for more than two days. When they turn, they'll attack everyone else in quarantine, potentially killing healthy survivors you were trying to save. Check daily, make decisions quickly, and clean out the quarantine zone before accepting new patients.
Important
Quarantine capacity is limited. Upgrade it early through your tablet's upgrade menu to handle multiple suspects simultaneously.
Resource Management
Your approved survivors need food, fuel, and medical supplies. Run out of any critical resource and your camp descends into chaos. Riots happen, people die, and your defensive capabilities crumble.
Check resource levels constantly by visiting each section of your base. The generator needs fuel to power your defenses. The dining hall requires food to prevent starvation. Medical supplies keep your quarantine zone functional.
Don't wait until you're empty. Order supplies through your tablet when you hit 30% capacity. Bulk orders are expensive, so regular smaller purchases keep costs manageable while maintaining stable supply lines.
Resource Priority System
- Fuel - Without power, your automated defenses fail during attacks
- Food - Starvation triggers riots faster than any other shortage
- Medical supplies - You need these for quarantine operations
- Ammunition - Only matters during defense sequences
Quarantine Zone: The Last Check
Defending Against Zombie Hordes
After several days of inspection duty, the infected will attack your checkpoint in organized waves. You'll control a drone equipped with a minigun and rocket launcher to eliminate threats before they breach your gates.
The minigun handles standard infected effectively. Use short, controlled bursts to conserve ammo while maintaining consistent damage output. Rockets are for clustered groups or armored variants that shrug off small arms fire.
Upgrade your weapons regularly. Each upgrade increases damage output and reload speed. As waves progress, stronger infected appear that require upgraded firepower to stop. Check your tablet's upgrade section after every successful defense to improve your arsenal.
Tip
Prioritize minigun reload speed upgrades first. Longer sustained fire matters more than raw damage when facing large hordes.

Campaign Mode Challenges
Beyond standard inspection duties, Campaign Mode throws special events and moral dilemmas at you. Command Center will demand specific actions that conflict with your survival instincts. Desperate refugees will beg for entry despite showing infection signs. Insurgents will attempt to infiltrate your checkpoint with forged documents.
Your choices cascade into consequences. Reject a Command Center order and face reduced supply shipments. Accept too many refugees and overwhelm your food reserves. Trust the wrong person and insurgents sabotage your defenses before the next wave.
There's no perfect solution to these scenarios. You're choosing between bad options and worse options, trying to keep your checkpoint operational long enough to reach evacuation. Every decision costs something. Make sure you can afford the price.
Your survival depends on making the right call every single time. One infected person approved means an outbreak in your camp. One healthy person liquidated means guilt and potential riots. The pressure never stops, the stakes never lower, and the infected never quit coming.
Welcome to Quarantine Zone: The Last Check. Your shift starts now, and it doesn't end until you're evacuated or overrun. Make every decision count, trust your tools, and remember that hesitation kills more people than the virus ever could.
