Sphere Defense tasks you with protecting the Earth from relentless invaders, out now

Sphere Defense: A Minimalist Tower Defense Experience Now Available

Developer Tomoki Fukushima has released Sphere Defense, a new tower defense game for mobile devices. The game tasks players with defending Earth from waves of enemies using strategically placed units.

While the core gameplay remains true to the tower defense genre—strategic unit placement, resource collection for upgrades, and increasing difficulty levels—Sphere Defense distinguishes itself with its minimalist aesthetic and vibrant neon visuals.

Successful defense earns players resources to upgrade their units and achieve victory. The challenge intensifies with each level, rewarding skillful players who can complete levels without taking damage with high scores.

Fukushima cites the classic tower defense game geoDefense by David Whatley as inspiration, highlighting its blend of simplicity, fun, and beauty.
