Nothing like having the neighbor boy invade your meticulously cut lawn... or space aliens, for the matter. Especially hostile ones. Ouch, what did you ever do to them? Some giant universal karma for the Indians perhaps? Who knows... Anyways, you obviously don't want your down overrun with aliens, especially those landing on your lawn. Use your magnetic indicators so that you can steer the aliens' rockets down to the ground- conveniently crashing into the aliens that have already left their ships. Just do not let them get to close. Have you seen those tentacles? If not, just beware even more.
