Key Decisions Day 2

Decision Point #1: The Injured Trader

Has supplies you need
Also has suspicious wound
Temperature: 37.8°C (slightly elevated)
UV: Clean scan

Correct Choice: Quarantine ⚠️

Wound needs observation
Not clearly infected yet
Supplies not worth risk

Decision Point #2: The Family

Mother, father, child (8 years old)
All appear healthy
Child coughing slightly
UV: All clean, Temp: All normal

Correct Choice: Pass family ✅

Cough is regular cold
No infection signs
Separating family causes problems

Day 2 Goals:

☐ Screen 15-20 survivors
☐ Use quarantine correctly
☐ Order first resources (food)
☐ Save $150 for upgrades
☐ Earn $120-180

Day 3: Resource Management

Morning: First Resource Order

What to Buy:

Food: 250 units ($110)
Fuel: 100 units ($130)
Save remaining money

Why This Order:

Food prevents riots
Fuel keeps power on
Medical supplies still sufficient

Increased Difficulty

New Challenges:

More survivors (20-25)
Faster processing expected
First hidden infection case
Budget pressure

Critical Encounter: Hidden Infection

The Deceptive Survivor:

Name: Sarah
Story: Escaped infected zone
Appearance: Clean, well-dressed
Temperature: 38.2°C
UV Light: Small mark on left forearm 🚨

Correct Choice: Eliminate ❌

UV confirms infection
Elevated temperature
Early stage but confirmed

Why It’s Tricky:

Looks healthy
Friendly demeanor
Tries to hide arm
Temperature not critical yet

Consequences:

If you pass her: Safe zone infection starts
If you quarantine: She turns in 24 hours, infects others
If you eliminate: Correct decision

Other Day 3 Encounters

Coughing and pale
UV: Clean

☐ Maintain budget above $150
☐ Earn $180-240

Day 4: Upgrade Decision

First Upgrade Choice: You can afford ONE upgrade:

Option A: Mini-Gun Damage +25% ($150)

Best choice for demo
Critical for Day 5 horde
Combat advantage

Option B: UV Light Range +30% ($180)

Better detection
But you already know how to use it
Less critical than combat

Option C: Food Storage +200 units ($100)

Saves money long-term
Not immediately useful
Skip for now

Recommended: Mini-Gun Damage ✅
