Singularity 7 #1-4 (2004) Complete

With the Earth laid waste by an assault from microscopic nanites, humanity hides in underground cities. But those cities are being destroyed by the 'Gosiodo' machine beings engineered to convert the remnants of humanity to the will of the nanites. It's up to seven men and women, seemingly immune to the nanotechnology, to fight back before there's nothing left to fight for. A stunning new series written and drawn by Ben Templesmith.
