SPHERE DEFENSE: Tower Defense is a free simulation game where players must defend their base from hordes of enemies. Developed by Tomnoki for mobile devices, this title allows you to utilize your resources, build a formidable defense, and upgrade necessary units to fend off outside factions.  

Playable from the top-down perspective, SPHERE DEFENSE: Tower Defense offers strategic gameplay. Users must stop waves of enemies from reaching a certain point—in this case, the base. The game also features neo visuals, which emphasize sleek abstract designs and neon lights rather than actual units. 

Defend The Sphere from invading forces 

SPHERE DEFENSE: Tower Defense follows the story of Earth, also known as The Sphere, as it faces the threat of extinction from invading forces. In turn, humanity has taken it upon itself to defend its home by working in underground facilities to produce the best weapon that has ever graced the Earth against invaders. Now, it is time for humanity to put counteroffensive measures. 

The game offers three difficulty levels: Easy, Normal, and Hard. So, whether you are a beginner at tower defense games, a casual player, or a seasoned one, it does not matter. The game has a catered difficulty tier for everyone, providing users with a challenging gaming experience. Each difficulty level contains 10 stages that last between five to 15 minutes, which can still be a short session overall. 

Here, there are seven types of units, divided into three categories: attack units, support units, and attack-support units. The attack units consist of three turrets, each designed for standard, area, and piercing attacks. The support units, however, include cooling and incendiary turrets. Meanwhile, the attack-support units feature fixed-point and linear attack turrets. Utilize these turrets to successfully fend off invaders.
