Ten years have passed since an unknown alien species invaded Earth. Hundreds of unmanned alien weapons platforms armed with deadly nanogens were unleashed throughout the solar system....

Nanogen Number 17
infected Earth's, soldiers--dissolving their body tissue as fast as cybernetic implants can replace it.

Nanogen Number 16
infected Earth's children--granting life until they reach age thirty, when their bodies will rot away.

Dr. Alex Denyer has been deactivating the remaining platforms, hoping to contain the nanogens and find a cure for those already afflicted--including his son. But the aliens are not done with their victims. The first weapons platform to enter the solar system in a decade has arrived--larger than any that preceded it and carrying an endless supply of nanogens.

And it's heading toward Earth....
