Earth Under Attack: Sphere Defense Released Today

Sphere Defense: A Minimalist Tower Defense Gem

Defend Earth from relentless enemy waves in Sphere Defense, the new tower defense game from developer Tomoki Fukushima. While the core gameplay—strategic unit placement and resource management to survive increasing difficulty levels—remains true to the genre, Sphere Defense sets itself apart with its stylish minimalist visuals and vibrant neon aesthetic.

Collect resources to upgrade your defenses and strategically position your units to repel incoming attacks. Mastering the art of defense will earn you valuable resources for upgrades, leading you to victory. Each level presents a tougher challenge, and perfect runs (no hits taken) yield high scores for bragging rights.

Fukushima created Sphere Defense as a tribute to the classic tower defense game geoDefense, created by David Whatley over a decade ago. He was inspired by its simplicity and captivating design.
