Developer Tomoki Fukushima has officially launched Sphere Defense, an innovative 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 vibrant neon lights, adding a fresh twist to the genre.

The core objective remains true to its roots: players must strategize the best placement of towers and units to fend off incoming attacks effectively. 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, enhancing your defensive capabilities as you progress through the game.

As you advance, the challenges become increasingly difficult, testing your strategic skills to the limit. For those who can master the game and clear levels without taking a single hit, high scores and ultimate bragging rights await.

"This game was developed as a homage to 'geoDefense', a tower defense 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 the developer, Tomoki Fukushima.
