Shooting Game in Space description

Earth is going to be invaded by evil alien spaceship, star-ship and unidentified flying object from outer space. Fortunately, you are the best pilot in the galaxy. Your mission is very simple which is to protect our planet (Earth) by destroying all of the asteroids and alien spaceships. Stay alive by avoiding shots and collision from the alien spaceship(s) or spacecraft(s). In order to get to the next level, you must destroy at least 95% of the asteroids and alien spaceships. In each level, if all of the asteroids and alien spaceships is destroyed, a bonus space ship or spacecraft is added. In level 17 and up, your space ship has extra firing power. It shoots three weapons simultaneously.
