Sphere TD layers deep customization onto tower defense, letting you craft modifier combinations that transform single towers into wildly different weapons—splitting projectiles, chaining attacks, bouncing around obstacles. With mining, drone deployment, and idle progression running alongside active play, you can push toward millions of viable builds or step back and let automation handle the grind while you optimize your next mod setup.
