Beginner's Guide
Learn essential survival tactics, infection detection methods, and base defense strategies to master Quarantine Zone: The Last Check.

Welcome to the Checkpoint
You're standing at humanity's last line of defense. Every survivor who approaches your station is a potential threat. One wrong decision means death for everyone behind you. This guide will teach you everything you need to survive.
What Makes This Game Different?
Think Papers Please meets zombie survival horror. You're conducting medical inspections, managing limited supplies, and dealing with the moral weight of sending potentially healthy people to their deaths.
- 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
How to Spot Infected Survivors

Skin Conditions
Eye Symptoms
Critical Signs
Essential Tools
Scanner
Your workhorse. Check for visible injuries, then activate UV mode to reveal hidden bite marks.
Stethoscope
Check breathing patterns. Irregular = quarantine. Virus breath = death approaching.
Thermopulsometer
Measures temperature and heart rate. Elevated = quarantine. Extreme = infected.
Syringe Scanner
Expensive but definitive. Use when other tools give conflicting signals.
Tool Priority Guide
| Situation | Best Tool | Action |
|---|---|---|
| Visible symptoms present | Scanner with UV | Check for hidden bites |
| No visible symptoms | Stethoscope | Listen for irregularities |
| Survivor seems nervous | Thermopulsometer | Check elevated vitals |
| Conflicting readings | Syringe scanner | Get definitive status |
| Aggressive behavior | Pistol | Neutralize immediately |
Managing Your Quarantine Zone
- Check quarantine patients within 24 hours
- Some will improve, others will deteriorate
- If someone degrades after a day - liquidate immediately
- Never leave infected for more than 2 days - they will turn and attack others
Resource Management

Fuel
Without power, automated defenses fail during attacks
Food
Starvation triggers riots faster than any other shortage
Medical supplies
Needed for quarantine operations
Ammunition
Only matters during defense sequences
Defending Against Zombie Hordes
- After several days, infected will attack in organized waves
- Control a drone with minigun and rocket launcher
- Minigun: Use short controlled bursts for standard infected
- Rockets: Save for clusters or armored variants
- Upgrade weapons regularly through your tablet
Symptom Decision Matrix
| Symptom | Severity | Decision |
|---|---|---|
| Yellow eyes, red skin, herpes | Cosmetic | Approve for entry |
| Conjunctivitis, bruises, freckles | Minor | Approve for entry |
| Elevated temp/pulse, cough | Moderate | Send to quarantine |
| Pale skin, skin rash, sick breath | Concerning | Quarantine + daily checks |
| Green skin, red eyes, bite marks | Critical | Immediate liquidation |
| Necrosis, virus breath, extreme vitals | Terminal | Immediate liquidation |
Campaign Mode Challenges
Beyond inspection duties, Campaign Mode throws special events and moral dilemmas. Your choices cascade into consequences.
- Command Center may demand actions that conflict with survival
- Desperate refugees will beg despite showing infection signs
- Insurgents attempt infiltration with forged documents
- No perfect solutions - only bad options and worse options
Your shift starts now. Make every decision count, trust your tools, and remember that hesitation kills more people than the virus ever could.
