Survive relentless enemy waves by strategically placing units, upgrade your defenses with collected resources, and conquer increasingly challenging levels in Sphere Defense, the new tower defense game from developer Tomoki Fukushima.
While the core gameplay remains true to the tower defense genre—strategic unit placement is key to repelling attacks—Sphere Defense distinguishes itself with minimalist visuals and vibrant neon aesthetics. Each successful defense earns you resources to power up your units, pushing you towards victory. The difficulty ramps up with each level, rewarding skillful players who can achieve perfect, hitless runs with high scores.
Fukushima explains the inspiration behind Sphere Defense: "This game is a tribute to 'geoDefense,' David Whatley's tower defense classic from over a decade ago. 'geoDefense' captivated me with its simple yet engaging and beautiful design."
