Space Purge is an action shooting game. You are the last defense of the Earth from space rocks approaching the planet. Fly into outer space and shoot the rocks before they fall to the Ground. The earth is one, so if even one stone flies past you, the game is over. However, you have three spaceships, so protect the Earth with everything you have. space shooter,defense game,earth defense,space rocks,action game,shooter game,cosmic battle,planetary protection,survival game,space combat,last defense,shooter
