Sphere Defense: A Tower Defense Classic Reborn on Android
Tomnoki Studio's Sphere Defense is a fresh take on the classic tower defense genre, drawing inspiration from the beloved geoDefense. The developer, a longtime fan of geoDefense, aimed to recreate its elegantly simple yet challenging gameplay.
The game's premise is straightforward: Earth ("The Sphere") faces annihilation by relentless invaders. Humanity, forced underground, scrambles to develop new technologies for a desperate counter-offensive. After years of setbacks, humanity finally amasses the firepower needed to fight back. You lead this counterattack, tasked with saving the planet.
Sphere Defense faithfully delivers the classic tower defense experience. You strategically deploy various units, each possessing unique strengths, to repel waves of enemies. Successful engagements reward you with resources to expand and upgrade your defenses. The challenge escalates with increasing difficulty levels.
Three difficulty levels are available: easy, normal, and hard. Each difficulty features 10 stages, with each stage lasting 5 to 15 minutes. See the game in action:
Sphere Defense offers seven distinct unit types, allowing for diverse strategic combinations. Offensive units include the Standard Attack Turret (single-target), the Area Attack Turret (area-of-effect), and the Piercing Attack Turret (for dealing with tightly-packed enemies).
Support units, such as the Cooling Turret and the Incendiary Turret, enhance your offensive capabilities. Specialized units like the Fixed-Point Attack Unit (precise missile strikes) and the Linear Attack Unit (satellite laser) add further strategic depth.
Download Sphere Defense from the Google Play Store and experience the thrill of this revitalized tower defense classic. Don't forget to check out our latest news on CarX Drift Racing 3 and its new features!
