Over 50 years ago the Earth was on a collision course with a comet. As a result humans were forced to leave the planet and find a new home. After many years of searching a new homeworld was found, unfortunately the local alien inhabitants were not very friendly and destroyed many homes and killed many people. Your task is to defeat these aliens before they finish off humans for good.
