Protect Earth: Sphere Defense Now Available

Sphere Defense: A Minimalist Tower Defense Gem Launches on Mobile

Developer Tomoki Fukushima has released Sphere Defense, a captivating tower defense game where players protect Earth from waves of enemies. While the core gameplay remains true to the tower defense genre—strategic unit placement and resource management are key to survival—Sphere Defense distinguishes itself with its stylish minimalist visuals and vibrant neon aesthetic.

The game's simple yet engaging mechanics involve strategically positioning units to repel incoming attacks. Each successful defense earns valuable resources, used to upgrade units and enhance defenses. Difficulty progressively increases, rewarding skillful players who can complete levels without taking damage with high scores and bragging rights.

Fukushima cites the classic tower defense game geoDefense as inspiration, highlighting its blend of simplicity and engaging gameplay. Sphere Defense aims to capture that same magic.
