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

by Max Apr 09,2025

Developer Tomoki Fukushima has officially launched Sphere Defense, a captivating new tower defense game where players are tasked with protecting the Earth from relentless enemy waves. While it may seem like a typical tower defense game at first glance, Sphere Defense distinguishes itself 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 strategically place towers and units to effectively 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, enhancing your defensive capabilities as you progress through the game.

As you advance, the difficulty ramps up, challenging you to refine your strategies and perfect your tower placements. For those aiming for the top of the leaderboards, clearing levels without taking any damage is the key to achieving those enviable high scores and bragging rights.

yt"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.
