New TD Game "Sphere Defense" Debuts, Inspired by 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, has recreated its elegantly simple yet challenging gameplay.

The Core Concept

The game's premise is straightforward: Earth ("The Sphere") faces an alien invasion, forcing humanity underground. After years of development, humanity finally has the firepower to counterattack. Players lead this counteroffensive to save the planet.

Gameplay

Sphere Defense faithfully delivers the core tower defense experience. Players deploy various units, each with unique strengths, to repel waves of enemies. Successful engagements yield resources for expansion and upgrades. The difficulty scales, demanding increasing strategic depth.

Three difficulty levels (easy, normal, hard) are available, each comprising 10 stages lasting 5-15 minutes. See the game in action:

Diverse Turret Arsenal

Sphere Defense features seven distinct unit types, offering strategic flexibility. Offensive units include the Standard Attack Turret (single-target), Area Attack Turret (area-of-effect), and Piercing Attack Turret (for dense enemy formations).

Support units like the Cooling Turret and Incendiary Turret enhance offensive capabilities. Specialized support-attack units such as the Fixed-Point Attack Unit (precise missile strikes) and Linear Attack Unit (satellite laser) add further tactical options.
