Enemy aliens have invaded your sector of space, and it is up to you to destroy them with the help of your armada. Engage the enemy with a number of different starships and weaponry at your disposal. Using in-game credits earned via destroying different enemy ships, you can purchase various cruisers, turrets and other abilities which can help you defeat your foes! Integrated within the game is the ability to show off your skills to the world by uploading a replay of each level you've beaten to facebook, twitter, youtube or mail with no hassle! No in app purchases, and no invasive ads that interrupt gameplay. See only the ads that you want to see to earn a boost in credits or to replay a level you were defeated on. Share and compete with your friends, to see who amongst you is the best alien scum slayer!
