Protocol Xeno (AppID: 2076430)

Earth has suddenly been thrust into the center of a galactic warzone, and now you must take charge and prepare mighty defenses. The aliens never let up for long, so you must carefully divide your attention between combating them and spending your resources. You may crush aliens with the moon or overwhelm them with your extreme partying, but they will only grow stronger. How long can you hold them off?
