Sphere Defense Is a New TD Game Inspired by geoDefense

Sphere Defense, a fresh tower defense game on Android developed by Tomnoki Studio, pays homage to the classic geoDefense by David Whatley, which captivated gamers over a decade ago. The developer, inspired by their childhood experiences with geoDefense, aimed to capture its beautifully simple yet challenging essence in Sphere Defense.

What’s the Premise?

The core concept of Sphere Defense revolves around the Earth, or 'The Sphere,' facing annihilation from invaders. Humanity, forced underground, has been piecing together new technology in a desperate bid to fight back. After enduring years of oppression, they've finally amassed enough firepower to launch a counterattack, and you're at the helm, tasked with saving the planet.

In terms of gameplay, Sphere Defense embraces the classic tower defense formula. You strategically place units, each with unique strengths, to fend off waves of enemies. As you accumulate kills, you earn resources to expand or upgrade your arsenal, with higher difficulties demanding more strategic planning.

The game offers three difficulty levels: easy, normal, and hard, each comprising 10 stages. Each stage lasts between 5 to 15 minutes, providing a varied and engaging experience. Get a sneak peek of the game in action below!

Set Up Turrets to Mow Your Enemies Down

Sphere Defense features seven types of units, which you'll need to strategically mix and match to survive. The attack units include the Standard Attack Turret for single-target eliminations, the Area Attack Turret for dealing with groups of enemies, and the Piercing Attack Turret, perfect for when enemies are lined up.

Support units like the Cooling Turret and the Incendiary Turret enhance your attack units' effectiveness. Additionally, there are support attack units such as the Fixed-Point Attack Unit for targeted missile strikes and the Linear Attack Unit for delivering satellite laser attacks.
