Las Vegas was the most populous city in the state of Nevada, internationally renowned as a resort city for gambling, shopping, and fine dining. In 2008, Las Vegas fell victim to a zombie outbreak. As a result, the military sealed the city with a 50-mile-perimeter blockade. Their plan was to obliterate the city to prevent further outbreaks. The city was soon wiped off the map, and its remains are currently sealed off by the government.
Chuck Greene, his wife Pam Greene, and daughter Katey Greene were in Las Vegas when a zombie outbreak of unknown origins broke out. Unfortunately, Pam got infected, and bit four-year-old Katey on her left arm. The father-and-daughter fled to the desert town of Still Creek, having to leave their deceased wife/mother back in Vegas. According to a news report on the radio, the military had set up a 50 mile perimeter around Las Vegas, which includes the 46-miles-away Still Creek, planning on wiping out the area in an effort to contain the outbreak. Other refugees from Las Vegas have reached Still Creek, only to be captured by the military (such as the infected Sharon) or forced to flee into hiding (such as Gemini, Nikki, Archie, and others).
