Planet Defense is an arcade shooting game where you protect a single planet from waves of incoming asteroids and alien threats. You control a planetary cannon that moves with your cursor and fires on command. The objective is to survive as many waves as possible, destroy large asteroids before they break into smaller fragments, and keep the planet intact.
Gameplay focuses on quick aim, target priority, and resource management. Each destroyed asteroid adds to your score. As you progress, enemy speed and frequency increase. The game rewards accuracy and fast reactions. Power ups and temporary shields appear to help you in tight moments. Planet Defense is easy to learn yet challenging to master, making it ideal for short arcade sessions or long high score runs.
Key mechanics include precise mouse aiming, single button shooting, score tracking, and escalating waves. The clear visuals and responsive controls keep the action tight. Use strategy to choose which threats to destroy first and when to save power ups for critical waves. The game appeals to players who enjoy fast action, reflex tests, and simple but deep shooting gameplay.
