Chicago

Chicago or also known as "Flat City" was a city in the United States. It had a population of 2.7million before its outbreak and was the first city in North America to report a case of the Virus. It was also the first city in the United States to have a wide-scale outbreak with at least one million deaths in the first 24 hours.

History
After its outbreak in May 2021 that killed around 1 million of its citizens, the city was left abandoned and all survivors were relocated to 'Quarantine Centers' in suburban Chicago. During this quarantine, many families were separated and those who were infected were presumably slaughtered. It was extremely criticised by the media who dubbed it as "Holocaust II".

The Quarantine Centers eventually collapsed due to pressure of food and power in around June-July 2021. There were also reports of the undead slowly appearing in random areas of the centers. All who survived the collapse were forced onto their own ways, with many heading to Canada or further West.

In late July 2021, the city was heavily firebombed and left in ruins by the American military, giving its common nickname the "Flat City".
