About Planetary Defense

Prepare for an intense survival challenge in Planetary Defense, a fast-paced shooter that combines modular building with bullet-hell action.

As the commander of a customizable battle machine, your mission is to defend against waves of relentless alien threats.

The core of the game lies in its modular block system: mix and match defense turrets, powerful weapons, and economic generators to craft a fortress that suits your playstyle.

As you progress, you'll face increasing dangers from flying saucers, swarm drones, and massive comets.

Success in Planetary Defense requires quick reflexes and strategic planning—use the breaks between waves to purchase upgrades, merge identical blocks for stronger variants, and evolve your machine into an unstoppable planetary guardian.

If you love roguelite survival games with deep customization, Planetary Defense will keep you hooked.
