Sphere Defense: Earth Under Alien Attack!

By AaronMar 13,2025

Strategize unit placement for optimal defense, gather resources for upgrades, and conquer increasingly challenging levels in Sphere Defense, a new tower defense game from developer Tomoki Fukushima. This game, a homage to the classic geoDefense, offers a unique twist on the genre with minimalist visuals and vibrant neon aesthetics. Defend the sphere (Earth) from relentless enemy waves, strategically positioning towers and units to survive each attack. Successful defenses yield resources for unit upgrades, leading to victory. Higher difficulty levels and the challenge of achieving perfect, hitless runs await those seeking high scores and bragging rights.

"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," says Fukushima.
