You are the Director of Earth's Planetary Defense Program.
Detect asteroid threats, analyze their composition, and deploy the right countermeasures.
Strategy Tips:
• Upgrade sensors first — early detection gives you more options
• Use reconnaissance probes to identify composition before striking
• Match your weapon to the asteroid type — wrong choice = poor results
• Rubble piles can fragment — use gentle methods like gravity tractors
• Multiple small deflections can be better than one risky big hit
• Deflection direction matters — push prograde/retrograde to change timing
