The year 2124 and mars as we know it has fallen, what was once a terraformed metropolis filled to the brim with people is now ghost town filled with the very same mechanical monstrosities that brought man-kind to it's knees and forced them to find shelter under the planet's surface. The one remaining hope for mankind lies in the hands of the Altims, augmented super soldiers made to withstand the sub-zero temperatures of the surface while also fighting back against the relentless assault of the Ultumite forces. One of such super soldiers encounters something he shouldn't have on his first expedition causing a chain reaction no one could predict.
