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

Strategically position your units for survival, gather resources to enhance your defenses, and conquer increasingly challenging levels in Sphere Defense, the new tower defense game from developer Tomoki Fukushima. This isn't your average tower defense game; Sphere Defense boasts minimalist visuals and vibrant neon aesthetics, adding a unique twist to the classic gameplay.

The core objective remains the same: defend the sphere (Earth) from relentless enemy waves. Successfully repel attacks earns you resources to upgrade your units, paving the path to victory. As you progress, the difficulty ramps up, rewarding skillful players who can achieve perfect runs with high scores.

"This game was developed as a homage to 'geoDefense,' a tower defense game created over 10 years ago by David Whatley. When I played 'geoDefense', I was deeply impressed by how such a simple game could be so fun and beautiful," the developer shares.
