Earth has way too many humans, so we aliens are moving them to some empty planets... whether they like it or not! For some reason, the humans keep shooting at us. Oh, well. Go ahead and use your spaceship to abduct... er... rescue as many as you can and deposit them on their new home planets. Try not to let them shoot you, and try not to drop them from too high off the ground. They don't bounce all that well. Keep in mind that the more of them you carry, the heavier your spaceship will be.
