Left 4 Dead 2 is a cooperative first-person shooter game. It is the sequel to Valve Corporation's award-winning Left 4 Dead. The game launched on November 17, 2009, for Microsoft Windows and Xbox 360 in the United States and November 20 in Europe; in 2010, Left 4 Dead 2 was made available to the Steam client for Mac OS X.[7] It builds upon the cooperatively-focused gameplay of the original and uses Valve's proprietary Source engine, the same game engine used in Left 4 Dead. The game made its world premiere at E3 2009 with a trailer during the Microsoft press event.[8]
Like the original, Left 4 Dead 2 is set during the aftermath of an apocalyptic pandemic, and focuses on four survivors fighting against hordes of the infected. The survivors must fight their way through levels, interspersed with safe houses that act as checkpoints, with the goal of reaching a rescue vehicle at the campaign's finale. The gameplay is procedurally altered by an artificial intelligence engine dubbed the "Director" that monitors the players' performance and adjust the scenario to provide a dynamic challenge. Several new features have been introduced: new types of infected, melee weapons, and a story-arc that connects the game's five campaigns together.[9]
When it was announced, it received a combination of positive and negative critical and community reactions. It also attracted an unusually high volume of pre-release controversy about the game's graphic content. In response, alterations were made to the cover art[10] and both Australia (due to having no R18+ rating) and Germany refused to rate the unmodified edition.[11]

Like its predecessor, Left 4 Dead is set two weeks after a worldwide pandemic of an infectious disease that rapidly transforms humans into zombie-like creatures and mutated forms that demonstrate extreme aggression towards non-infected (much like the ones in 28 Days Later). Few humans are immune to the disease, still carrying the infection but showing no symptoms. The Civil Emergency and Defense Agency (CEDA) and the U.S. military create safe zones to attempt to evacuate as many American survivors as possible. Left 4 Dead 2 introduces four new survivors—Coach, Ellis, Rochelle, and Nick—who are immune to the disease and have individual back stories that are provided through character dialog. Unlike the first game, which had no significant story development, the five campaigns in Left 4 Dead 2 are set across a story arc,[12] set in the Southern United States, which starts in Savannah, Georgia, and ends in New Orleans, Louisiana.[8][9] The four survivors have to fight their way through the hordes of infected, using safehouses along the way to rest and recuperate in order to reach extraction points.

After climbing to the roof of a hotel in Savannah to be rescued, the survivors find themselves abandoned by rescue helicopters, and so make their way to the local mall, after hearing word of a second CEDA evacuation point there ("Dead Center"). After a brief encounter with a gun store owner, Whitaker (voiced by Dayton Callie), the survivors discover that the mall is overrun and all of the CEDA agents have either been killed or have become infected themselves. The four then use a stock car to bust out of the mall and travel towards New Orleans. On their way there, they encounter the original survivors featured in Left 4 Dead at the portside town of Rayford ("The Passing"), before finding the highway completely blocked by wrecked vehicles. The survivors are then forced to travel through a still-operating (but abandoned) amusement park, and start a huge fireworks-and-lights show used by the rock band, The Midnight Riders, in order to attract the attention of a helicopter pilot ("Dark Carnival"). After being rescued, they realize their pilot has been infected. Nick is forced to kill him, which causes the helicopter to crash into a bayou ("Swamp Fever"). They find brief shelter in a plantation mansion and make radio contact with a boat captain named Virgil who can get them to rescue, but he needs additional diesel fuel to make it to New Orleans. Amid a torrential downpour, the survivors go ashore, make their way through an abandoned sugar mill to a gas station to get fuel supplies, and return to the boat ("Hard Rain"). Virgil takes them to New Orleans where the military appears to be evacuating civilians. The group head to the extraction point, but discover that the military is actually bombing bridges to cover their retreat ("The Parish"). The survivors then make their way across a lift bridge amidst a mass of infected and board the last military helicopter leaving the city before the bridge is destroyed by an air strike. Judging from their dialog, the military pilots suspect that the survivors are "carriers."
Although the survivors' fate after evacuation is left unexplained after the bridge finale, Chet Faliszek, the game's writer, said that the military is taking survivors to cruise ships in an attempt to escape the worldwide infection.[13]
The Sacrifice campaign takes place before the main events of Left 4 Dead 2, sometime before the events of The Passing. The survivors from the first Left 4 Dead arrive at the portside town of Rayford in order to search for a boat that could take them to the Florida Keys. After finding an adequate vessel, the survivors manually have to start up generators in order to lift a bridge for their boat to pass through. One survivor (canonically Bill) sacrifices themselves in order to kick-start a generator once the lift jams, so that the others may reach safety.
[edit]Gameplay

Like its predecessor, Left 4 Dead 2 is a first-person shooter with a heavy emphasis on cooperative gameplay. The game presents six new campaigns, each composed of three to five smaller maps. In the first two to four maps of any campaign, the survivors attempt to reach a safehouse, while the final stage requires the survivors to call for rescue and either survive a prolonged onslaught until rescue arrives, pass through an especially challenging gauntlet of infected to reach a rescue vehicle, or collect and deploy fuel cans to facilitate an escape.
Each survivor can carry one main weapon,[14] and either a melee weapon or pistols as a secondary weapon. Though melee weapons cause extra damage to the infected when struck, the survivors can use any other weapon or item for weaker melee attacks and to temporarily push the infected back. Players also carry a flashlight, but may startle the infected. They may also carry a single first aid kit, special ammo pack, or a defibrillator; in addition to either pain pills or adrenaline shot. They may also carry a single throwable weapon—Molotov cocktails to set an area on fire, pipe bombs to attract any nearby infected to the flashing light and sound it makes until it explodes, and Boomer bile, which can be thrown at infected to cause them to turn on each other.
Because many of the special infected can quickly finish off a survivor if they are not rescued, the game encourages players to stay and work together to traverse the level safely. To enable situational awareness of other players, players are shown the health and status of their fellow survivors. If a player does not have direct sight of another survivor, they will be shown the survivor's highlighted silhouette. As they take more damage from the infected, players move slower. If a survivor's health drops to zero, they become incapacitated and can only fight off the infected using pistols—even if they are carrying a melee weapon—until rescued by another survivor. If a character dies, they remain dead until the next level, unless revived by a defibrillator, or, in Campaign or Single-player mode, reappear in a "rescue closet" to be freed by the other survivors. Should all the survivors be killed or incapacitated, or if all the human-controlled survivors die, the game is over, and players must restart that chapter.
Left 4 Dead 2 retains the three game modes of the original game—Campaign, Versus, and Survival—and adds a new game mode called Scavenge. In Campaign mode up to four human players fight against the computer-controlled infected to make their way between safe houses; any survivor not controlled by a human player is controlled by the computer. In Versus mode up to four other human players take control of the various Special Infected who try to prevent the Survivors from reaching the next safe house. Special Infected are randomly assigned and one player typically controls a "non-pinning" infected which cannot "trap" a survivor (such as a Boomer or Spitter). Occasionally, as determined by the "AI Director", players will become the Tank, who has a massive amount of health and strength. The two teams swap sides once per chapter and are scored based on their play through as Survivors. Points are given during chapter progress, the more distance, the more points. If both teams make it to the saferoom with all four survivors, a 25 point tie-breaker is awarded to the team that dealt the most combined damage as special infected. Versus mode typically requires at least 1 human player on each team. Survival mode is a timed challenge where the survivors are trapped in a section of the campaign maps, and try to survive as long as possible against an unending onslaught of infected. In the new four-on-four Scavenge mode, the survivor players are required to collect and use as many of the sixteen gas canisters scattered about a level to maintain the fuel of power generators, while the infected players attempt to stop them.[15]
The game also features a realism mode, which can be enabled at any difficulty for either campaign or versus modes. This mode removes some of the video-game aspects from the gameplay: survivors are not able to see the silhouettes of their teammates; if they die, they can only be revived with a defibrillator kit and will not respawn later in the level.[16] Damage dealt to Infected is also changed, with headshots dealing more damage to enemies, whereas limb or body shots require more shots, making gameplay even more of a challenge.[17] Additionally, the Witch will now kill any survivor it would have merely incapacitated. Items such as defibrillators, throwable items and weapons will only glow when the player is within a few feet, forcing the players to investigate more thoroughly. Designed to force players to work closely together and rely on voice communication, the realism mode was created to give players a way "to be challenged as a team" without having to increase the difficulty level of the game.[16]
A new game mode called "Mutation" was added as part of the first major add-on for the game, "The Passing". This mode is dynamic and will be updated biweekly by Valve to feature new game play ideas. The first week featured a "Realism Versus" mode, which combined the features of the "Realism" and "Versus" modes.[18] "Realism Versus" mode proved popular with players leading Valve to introduce it as a permanent gameplay mode.[19] Other Mutations have included forcing the players to use only melee weapons like the katana or chainsaw, reducing the number of Survivor players to 1, or increasing the number of special infected that could be generated by the Director.
