Concept art for a personal project.
The ruined city is still bustling with nano technology, endlessly carrying out their original tasks long after their creators demise. However, without a watchful eye some have become corrupted and caused small sections of the city to become impassable from the ground. Though eerily beautiful to look at, the parasitic nanites that now call these areas home will invade the bodies of any organism that should stumble into their midst and literally destroy them from the inside out. Our hero will have to find another way around it would seem.
