How to Play Astro Tower Defense

Game Basics

Defend your cosmic territory by placing strategic towers along the enemy path. Enemies will try to reach the end of the path - don't let them!

Each enemy that reaches the end will cost you one life. Lose all your lives and it's game over.

Tower Types

Sun Tower: Area of effect damage, great for groups of enemies.

Saturn Tower: Slows enemies, allowing other towers more time to attack.

Uranus Tower: Random effects, can be powerful but unpredictable.

Zodiac Tower: Special abilities that vary based on current zodiac sign.

Premium Towers: Chiron (healing) and Lilith (dark energy) offer advanced capabilities.

Upgrades & Aspects

Use cosmic credits to upgrade your towers and purchase special aspects:

Trine Aspect: Creates strong synergy between nearby towers.

Opposition Aspect: Provides unstable but powerful effects.

Cosmic Shield: Grants temporary invulnerability to your towers.

Retrograde: Briefly reverses enemy movement.

Progression

Complete all 12 zodiac stages in Campaign mode to unlock special rewards.

Test your skills in Endless mode with increasingly difficult waves of enemies.

Earn higher ranks (Bronze, Silver, Gold, Platinum, Cosmic) as you progress.

Tips & Strategies

Placement Strategy

  • Place Saturn (slow) towers near the beginning of the path to maximize their effect
  • Position Sun (AoE) towers where paths converge or at sharp turns
  • Use Uranus towers in the middle of your formation for random benefits
  • Upgrade your most strategically placed towers first

Economy Management

  • Don't spend all your credits at once - save some for emergency upgrades
  • Watch ads to earn extra credits when needed
  • Focus on towers that provide the best value for their cost
  • Balance between building new towers and upgrading existing ones

Advanced Tactics

  • Combine tower types for maximum effect (slow + damage)
  • Use Retrograde when enemies are clustered together
  • Activate Cosmic Shield when boss enemies appear
  • Pay attention to enemy types and adjust your strategy accordingly
  • In Endless mode, focus on scalable strategies rather than quick fixes
