Sphere Defense: Earth Under Attack, Game Now Live

Strategize unit placement for maximum survival, collect resources for powerful upgrades, and conquer increasingly challenging levels in Sphere Defense, the minimalist tower defense game from developer Tomoki Fukushima. Defend the sphere (Earth!) from relentless enemy waves, utilizing sparkly neon visuals and strategic tower placement to fend off attacks. Each successful defense earns resources to upgrade your units, leading to ultimate victory. Master the levels without taking damage to achieve high scores and bragging rights.

Inspired by the classic geoDefense, Sphere Defense offers a fresh take on the tower defense genre. As the developer states, "This game was developed as a homage to 'geoDefense', a tower defence 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,"
