Global Defense System

You control a cursor that manages a planet's defenses. Your main job is to place automated laser turrets along the planet's surface to intercept incoming asteroids. Between waves, you use earned credits to buy more turrets or upgrade their firing rate and power. The asteroids come in predictable patterns at first, but later waves introduce different sizes and speeds, forcing you to adjust your placements. The pace is methodical, building to moments of frantic clicking as you scramble to reinforce a weak point. It feels like a tense, solitary game of chess against the sky.
