Story
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 four 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 through the bayou country, and climaxing in New Orleans' French Quarter.

Gameplay
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. 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. The game features several multiplayer options including 2-8 player online and offline support in several modes seen in the first game, including Campaign, Versus, and Survival, as well as the new Scavenge Mode. This new multiplayer option tasks players, in the role of survivors to find a limited number of fuel canisters hidden in a level in order to keep their individual generators going, while other players in the role of the infected try to stop them. In addition the game features very strong co-op play support, with 2-player support locally and 2-4 player support online.

The game features a wealth of melee weapons and additional items handy for battling enemies up-close and personal. Along with melee weapons seen in the first game, players can look forward to wielding new weapons like axes, chainsaws, frying pans, etc. Firearms are also available, but seeing as zombie fighting usually requires a little elbow grease, melee weapons are the mainstay. In addition, players can carry other useful items, including a variety of throwing weapons and several different kinds of support items, like flashlights to startle enemies and light the way in dark environments and healing items like first aid kit and defibrillator kits.

Customize with AI Director 2.0
Introducing the AI Director 2.0, Left 4 Dead 2's dynamic gameplay is taken to the next level by giving the Director the ability to procedurally change weather effects, world objects, and pathways in addition to tailoring the enemy population, effects, and sounds to match the players' performance. The result is a unique game session custom fitted to provide a satisfying and uniquely challenging experience each time the game is played.
