Innovative TD Game "Sphere Defense" Borrows Inspiration from "geoDefense"
Sphere Defense: A Classic Tower Defense Experience on Android
Tomnoki Studio's Sphere Defense is a new tower defense game for Android, drawing clear inspiration from the classic geoDefense by David Whatley. The developer, a longtime fan of geoDefense, sought to recreate its elegantly simple yet challenging gameplay.
The Story
Earth, or "The Sphere," faces imminent destruction at the hands of alien invaders. Humanity, forced underground, has finally developed the technology to fight back. You lead this counterattack, tasked with saving the planet.
Gameplay
Sphere Defense faithfully delivers the classic tower defense experience: strategically place units with unique strengths to repel waves of enemies. Successful engagements earn resources for upgrading and expanding your defenses. Higher difficulty levels demand increasingly sophisticated strategies.
The game offers three difficulty settings (easy, normal, hard), each with 10 stages lasting 5 to 15 minutes. See the gameplay in action:
Diverse Units for Strategic Defense
Sphere Defense features seven distinct unit types, offering strategic depth through varied combinations. Offensive units include the Standard Attack Turret (single-target), Area Attack Turret (area-of-effect), and Piercing Attack Turret (for dealing with tightly packed enemies).
Support units such as the Cooling Turret and Incendiary Turret enhance your offensive capabilities. Additional support-attack units like the Fixed-Point Attack Unit (precise missile strikes) and Linear Attack Unit (satellite laser fire) provide further tactical options.
