The main objective of the game "Orbits Planet Defense" is to defend a planet with revolving orbital defenses. In order to stop or eliminate approaching asteroids, adversaries, or projectiles, players must time the motions of shields or weaponry that orbit the planet. Because of the constant orbiting motion, precise taps or swipes are needed to change position and stop threats. Attack speed and enemy patterns increase in complexity as levels advance, necessitating fast reflexes and clever timing. Power-ups can improve firepower or protection, giving survival more depth. The objective is to avoid hits, keep orbit under control, and withstand waves of attacks that get more intense.
