Infected

An unstoppable virus was 'released'... It spread across North America, leaving the US devestated. No one is really sure exactly where it started, only that it was rumored to come from one of those 'secret' government facilities. Once it got to the larger cities it spread too quickly and what was left of the military forces could not contain it. A small number survived the outbreak, now they must fight those who were infected as well as other survivors in some cases. The world is a scary place, just surviving one more hour is a challenge and do you really want to?
