About Astra: Planet Defense

Turn an entire planet into your ultimate weapon.
Astra is a 3D space defense game about building an armed world and holding off incoming fleets. Your weapons fire automatically. Tap an enemy to focus fire, slow time when the pressure rises, and trigger emergency defenses to survive.

SHORT MISSIONS. NEW BUILDS.
Start with a 90-second defense. Later missions last from 2 minutes 30 seconds to 4 minutes. Pick from combat evolutions as you fight and discover a build that works for you.

BUILD YOUR BATTLE PLANET
Upgrade turrets and special weapons. Restore your planet's hull and shields. Spend recovered energy on permanent upgrades before your next deployment.

8 SECTORS. 40 OPERATIONS.
Face formations, armored ships and command ships. Hold out until extraction to earn the full reward and advance. If defeat is near, extract early to keep part of your energy.

STAY FOR THE LONG FIGHT
Complete the first operation to unlock an optional 10-minute endurance challenge. Choose between short chapter missions and a longer defense.

ADS AND PURCHASES
Optional rewarded ads grant extra energy. Interstitial ads may appear after some missions. Ad removal is an optional one-time purchase. Ads and purchases require a network connection.
