Left 4 Dead 2

Left 4 Dead 2 is set at roughly the same time as the original - just after the outbreak that turned most of the population into various zombie mutants. Players assume the role of 4 new "Survivors," each with their own personality and new dialog. The game leads these "Survivors" through the southeastern region of the US - from Savannah, Georgia thru the bayou country, and climaxing in New Orleans' French Quarter.
