Sphere Defense: Protect Earth from Invaders, Now Available

Authore: RyanUpdate:Apr 21,2025

Developer Tomoki Fukushima has officially launched Sphere Defense, an innovative tower defense game where players are tasked with protecting Earth from relentless enemy waves. Far from being just another typical tower defense game, Sphere Defense distinguishes itself with its minimalist visuals and captivating neon lights, adding a unique twist to the genre.

In Sphere Defense, the core objective remains faithful to the genre—players must strategically place towers and units to fend off incoming attacks. Each successful defense grants valuable resources, enabling players to upgrade their units and inch closer to victory. As you progress, the difficulty ramps up, challenging you to clear levels without taking a hit and achieve high scores for ultimate bragging rights.

Tomoki Fukushima shares that Sphere Defense was inspired by 'geoDefense,' a game developed over a decade ago by David Whatley. He notes, *"This game was developed as a homage to 'geoDefense'. When I played 'geoDefense', I was deeply impressed by how such a simple game could be so fun and beautiful."*
