Earth: An advanced inhabitable world in the ideal colonizable range. Moderate temperatures and consistent weather patterns make this planet an incredible resource, along with a wealth of animals and wildlife beyond most worlds. Inhabited by the sentient species designated "Humans," Earth would likely have joined the galactic community of its own accord. Levels of technology in local populace indicate a sharp trend towards interstellar travel, but still needs to make the last push to acquire reasonable interstellar technologies. Up until quite recently, Earth has not been a fully classified planet and was largely unknown. Due to biotic activity in the quadrant, however, attention has been drawn to Earth and many other possibly habitable planets in the regions, primarily for quarantine and control tactics.

Matthew Todd was not a particularly unique human being before the meteors struck the earth. Average athletics, above average intelligence, but somewhat gifted in marksmanship, the post-apocalyptic earth has been a trial by fire for him and many others. Creatures that resemble bastardized wolves roam the land in packs numbering in the thousands. With entire cities decimated, those that remain are left with the harsh reality that they may be witnessing the end of humanity.

And yet, there is a chance. Humanity knows they are not alone in the universe - the wolves are case enough for that - but what they do not know is that they are not alone in their plight. They are not without aid. Obelisks descend from the sky, giving the people a means to fight back. With tools ranging from guns to advanced mechanical apparatus and more bizarre tools, the people must cull the Biotics. Or, be consumed by the ever growing and mutating threat.

Join Matthew in the fight to exterminate the Biotic threat, and to ensure the survival of human kind!
