The game features several multiplayer options including 2-8 player online and offline (via system link) support in several modes seen in the first game, including Campaign, Versus, and Survival, as well as the new Scavenge Mode. As you would expect in a scenario where you are regularly surrounded by masses of the undead, it is very good thing to have plenty of help, as well as weapons at your disposal, and Left 4 Dead 2 has players covered on both accounts.
Just as with the original Left 4 Dead, Left 4 Dead 2 is a first-person shooter which pits players against hordes of zombie-like enemies. The game leads these 'Survivors' through the southeastern region of the US - from Savannah, Georgia through the bayou country, and climaxing in New Orleans French Quarter. Players assume the role of four new 'Survivors,' each with their own personality and new dialog. 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.
