Norfolk County (Post Apoc)

The year is 2046, CEDA releases a "cure" for many major infections and viruses, It backfires during winter, Causing the cured to lose their minds and start cannibalistic needs. Many people notice the panic and flee to the airport, but the military seals it off and guns down most of the civilians. CEDA panics realizing this, they lock down the main base and all the outposts, only to be attacked by an unknown corporation. CEDA was wiped off the map with these attacks. You start as a character emerging from the bunker in the town, to scavenge what was left behind and then escape.
