This free action games is as well one of the best shooting games out there. It is your mission to destroy alien intruders trying to invade your home planet. The defense on your planet is not strong enough to withstand the numerous alien spaceships trying to destroy it. Therefore the great nation of Elinglo hired you to help them prevent further attack on this planet. Your spaceship is equipped with some amazing firearms and rockets but in the course of the game you will still need to upgrade to more sophisticated arms and buy some additional shields for your spaceship. Occasionally you will have to build a self repair unit on the planet as well. Those aliens are just to many to keep them all away just by yourself.
