Crew Consumption
1 Crew = 1.08 O₂ per day
Consumption increases slightly on Hard difficulty
Oxygen Production
Primary source:
Algae Bed
Secondary: Leaf Greens (minor)
Failure States
<80% atmosphere: morale decline
<50% atmosphere: severe morale loss
0% atmosphere: suffocation begins
Balancing Tips
1 Algae Bed supports ~3 crew in steady state
Always maintain surplus
Early growth ramp takes ~20 days
