Planetary Defense is a fast-paced survival shooter where you assemble a powerful battle machine using modular blocks and face relentless threats from all directions. Mix and match defense, weapon, economy, and upgrade blocks to craft a build that matches your playstyle, then put it to the test across multiple arenas with unique enemy patterns and challenges.
Survive intense runs against waves of flying saucers, attack drones, and dangerous comets. Wipe out incoming threats, stay alive as long as possible, and use the breaks between stages to purchase new blocks or merge identical ones to evolve your machine. Experiment with different setups, adapt to escalating danger, and become the final line of planetary defense.
