The protagonist of Orbits-Defense games is a strong guardian core that is positioned in the center of a circle and is entrusted with protecting its domain from waves of approaching dangers. This core may shoot missiles, extend its orbit, and tactically swap defenses to stop or destroy attackers. It is surrounded by revolving shields and energy rings. Because the guardian must switch up defenses, line up weapons with approaching attackers, and strike a balance between offense and defense, the game is all about time. Upgrades increase the character's strength, enabling stronger blasts, faster rotations, and a broader orbital reach, resulting in a fierce rhythm of strategy and survival.
