DRW Las Vegas

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.

Dead Rising 2: Case Zero
Chuck Greene, his wife, and his daughter Katey were in Las Vegas when a zombie outbreak of unknown origins broke out. Unfortunately, Chuck's wife was infected, and bit four-year-old Katey on her 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).

Dead Rising 2
By the end of Dead Rising 2, is discovered that the city outbreak was caused by Phenotrans, in order to haverest queens.
