Space Purge is an engaging space shooter game available as a Chrome add-on. Players are tasked with protecting Earth from a relentless barrage of asteroids threatening to cause catastrophic damage. The objective is to navigate a rocket through space, shooting down meteorites with precision to prevent them from impacting the planet.

As players progress, they can collect various boosters that enhance their weaponry, restore health, and activate shields for added defense. The game emphasizes quick reflexes and strategic shooting to ensure that no meteorites pass by, as each one brings Earth closer to destruction. The controls are user-friendly, requiring only mouse movement to play.
