A lot of people fear an alien invasion while others relish the idea. Whichever category you fit in to, there is no time for empathy here. All of the aliens must die and it is your job to kill them. Use WASD to move your spacecraft through space. Use your mouse to spin the craft in whichever direction you need to face and shoot the aliens with the left mouse button. After an alien is destroyed, it will leave behind some debris that you'll need to grab to pick up points. You better hurry up, because you must kill all of the aliens.
