In this game, you have ten thousand seconds to kill all the aliens. To kill the aliens, you have to click on an alien to kill it. If your screen changes to a city before you kill all of them, you lose, if it changes after you kill them, you win. If you think you killed all of them,don't be to sure; recheck for any survivors! Good luck!
