"Sphere Defense: Protect Earth from Invaders, Now Available"

Author: Aiden Apr 18,2025

Developer Tomoki Fukushima has officially launched Sphere Defense, a captivating new tower defense game where players are tasked with protecting the sphere, essentially Earth, from relentless waves of enemies. While it might seem like just another tower defense game at first glance, Sphere Defense sets itself apart with its minimalist visuals and striking neon lights, offering a fresh twist on the genre.

The core objective remains true to the genre: players must strategize the optimal placement of towers and units to fend off incoming attacks. Each successful defense not only brings you closer to victory but also rewards you with valuable resources. These resources are crucial for upgrading your units, enabling you to tackle the increasingly challenging levels with greater ease. As the difficulty ramps up, the game tests your skills further, rewarding those who can clear levels without taking any damage with high scores and ultimate bragging rights.

Sphere Defense was inspired by 'geoDefense,' a tower defense game created over a decade ago by David Whatley. Tomoki Fukushima, the developer, shares, *"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."*
