Left 4 Dead 2

Left 4 Dead 2 is the sequel to the best-selling and critically-acclaimed co-operative multiplayer smash from Valve. The title adds melee combat to the award-winning L4D style of play, with items such as a chainsaw, frying pan, axe, baseball bat, and more. The setting is 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 south-eastern region of the US - from Savannah, Georgia thru the bayou country, and climaxing in New Orleans’ French Quarter. Left 4 Dead 2 offers a much larger game than the original with more co-operative campaigns, more Versus campaigns, maps for Survival mode at launch, and more...
