Introduction

Your checkpoint in Quarantine Zone: The Last Check is more than just an inspection station - it’s a lifeline for hundreds of survivors. Poor resource management means riots, system failures, and mission failure. Excellent management means smooth operations and maximum survival rates.

This guide covers everything you need to know about managing your base effectively: resources, budgets, upgrades, and optimization strategies.

The Three Critical Resources

1. Food 🍞

Purpose: Feeds survivors in your evacuation zone

Consumption Rate:

• 1 unit of food per survivor per day
• Starts with 50-100 survivors

• Maximum: 2,000 units (fully upgraded)

What Happens When Food Runs Out:

• Hour 1-6: Complaints and unrest
• Hour 6-12: Riots begin forming
• Hour 12-24: Full riot, checkpoint shutdown
• Hour 24+: Mission failure/Game Over

Ordering Food:

• Small batch: 100 units = $50
• Medium batch: 250 units = $110 (12% discount)
• Large batch: 500 units = $200 (20% discount)
• Recommendation: Order 250-unit batches for efficiency

2. Fuel ⛽

Purpose: Powers generator, equipment, lighting, and defense systems

Consumption Rate:

• Recommendation: Order 100-unit batches regularly

3. Medical Supplies 💊

Purpose: Treat injuries, provide quarantine care, general health

Consumption Rate:

• Passive: 2-3 units per day (general healthcare)
• Per injury treatment: 5-10 units
• Per quarantine patient: 3 units per day

Storage Capacity:

• Initial: 100 units
• Upgradeable to 200 units
• Maximum: 400 units

What Happens When Medical Supplies Run Out:

• Injured survivors deteriorate
• Quarantine patients may die
• Morale decreases
• Infection spread risk increases

Ordering Medical Supplies:

• Small: 25 units = $40
• Medium: 50 units = $70 (12.5% discount)
• Large: 100 units = $125 (18.75% discount)

Budget Management

Starting Budget

You begin with $500 and earn money through:

• Successfully processing survivors: $5-10 per person
• Completing daily quotas: $50-100 bonus
• Perfect screening (no mistakes): +20% earnings
• Catching infected before passage: $15 bonus each

Income Optimization

Maximum Earnings Strategy:

1. Screen Accurately - No false positives waste quarantine space
2. Process Efficiently - More survivors = more income
3. Meet Daily Quotas - Always hit target numbers
4. Catch Infections Early - Bonus for each detection
5. Minimize Mistakes - Letting infected through costs money

Daily Income Targets:

• Early game (Days 1-5): $150-250/day
• Mid game (Days 6-15): $300-500/day
• Late game (Days 16+): $500-800/day

Spending Priorities

Critical (Always Have Budget For):

1. Food when below 200 units
2. Fuel when below 100 units
3. Medical supplies when below 50 units

Important (Next Priority): 4. Weapon upgrades after horde attacks 5. Tool upgrades for better detection 6. Storage capacity expansions

Optional (When Budget Allows): 7. Aesthetic improvements 8. Comfort upgrades for survivors 9. Advanced systems

Resource Management Strategies

The 30-40-50 Rule

Never let resources drop below these thresholds:

• Food: 30% capacity (e.g., 150/500 = time to order)
• Fuel: 40% capacity (e.g., 120/300 = time to order)
• Medical: 50% capacity (e.g., 50/100 = time to order)

Why These Numbers:

• Gives buffer for unexpected events
• Allows time for delivery
• Prevents emergency buying at poor rates

Daily Resource Check Routine

Every Morning (Game Day Start):

1. Check food levels - Calculate days remaining
2. Check fuel levels - Assess daily burn rate
3. Check medical supplies - Factor in quarantine patients
4. Review budget - Can I afford today’s needs?
5. Place orders BEFORE starting screening

Every Evening (Game Day End):

1. Count today’s survivor intake
2. Calculate tomorrow’s food needs
3. Adjust fuel estimates for horde attacks
4. Save enough budget for emergencies

Bulk Buying Strategy

Food Buying Guide:

Survivors	Daily Consumption	Order Size	Order Frequency
50-100	50-100 units/day	250 units	Every 2-3 days
100-200	100-200 units/day	500 units	Every 2-3 days
200+	200+ units/day	500 units	Every 2 days

Fuel Buying Guide:

• Early game: Order 100 units every 5-7 days
• Mid game: Order 100 units every 3-4 days
• Late game: Order 200 units every 5-6 days
• Before expected horde: Order extra 100 units

Crisis Management

Food Emergency

When food drops below 50 units:

1. Immediate: Order food even if expensive
2. Short-term: Slow survivor intake temporarily
3. Long-term: Upgrade food storage ASAP

Prevention:

• Set reminder at 200 units remaining
• Order 250-500 units in advance
• Never spend food budget on other items

Fuel Emergency

When fuel drops below 30 units:

1. Critical: Order fuel immediately (top priority)
2. Emergency: If can’t afford, slow operations
3. Do NOT: Let it hit zero under any circumstance

Prevention:

• Check fuel daily without fail
• Order at 100 units remaining
• Always keep $150 emergency fuel budget

Medical Supply Shortage

When medical supplies drop below 20 units:

1. Limit quarantine intake temporarily
2. Order medical supplies ASAP
3. Triage: Treat critical cases only

Prevention:

• Maintain 50+ unit buffer
• Order when reaching 50 units
• Budget $100 for medical emergencies

Budget Crisis

When budget drops below $100:

1. Focus: Process more survivors for income
2. Cut: Delay non-essential upgrades
3. Prioritize: Keep fuel and food stocked
4. Earn: Perfect screening bonuses

Optimization Tips

Maximize Efficiency

Processing Speed:

• Screen 80-100 survivors per day early game
• Increase to 120-150 mid-to-late game
• Fast but accurate = maximum income

Resource Rotation:

• Don’t order all resources same day
• Stagger orders to maintain cash flow
• Order food Day 1, fuel Day 2, medical Day 3, repeat

Upgrade Timing:

• Upgrade after successful horde defense
• Don’t upgrade right before expected attack
• Save $300-400 for emergency orders always

Advanced Strategies

1. The Pre-Order Strategy Place orders one game day BEFORE you need them:

• Delivery takes time in-game
• Prevents emergency situations
• Allows bulk buying discounts

2. The Budget Buffer Always maintain $400-500 in reserve:

• For unexpected resource spikes
• Emergency situation response
• Upgrade opportunities

3. The Quarantine Rotation Efficient quarantine management:

• Check patients exactly every 24 hours
• Clear recovered patients immediately
• Free space for new uncertain cases
• Reduces medical supply waste

Common Mistakes

❌ Mistake #1: Reactive Ordering

Problem: Only ordering when resources run out
Why It Fails: Delivery delays cause shortages
Solution: Order at 30-40% remaining threshold

❌ Mistake #2: Upgrade Hoarding

Problem: Saving all money for upgrades
Why It Fails: Can’t afford emergency resources
Solution: Maintain $400 minimum budget always

❌ Mistake #3: Ignoring Storage Upgrades

Problem: Only upgrading weapons/tools
Why It Fails: Can’t buy in bulk, miss discounts
Solution: Storage upgrades are cost-effective

❌ Mistake #4: Unplanned Spending

Problem: Buying upgrades without budget plan
Why It Fails: No money for resource orders
Solution: Plan weekly budgets and stick to them

❌ Mistake #5: Neglecting Medical Supplies

Problem: Focusing only on food and fuel
Why It Fails: Quarantine patients die, morale drops
Solution: Medical supplies are equally important
