Left 4 Dead 2 Requirements Pc

[Eva Dunckel]

Left4 Dead 2 builds upon cooperatively focused gameplay and Valve's proprietary Source engine, the same game engine used in the original Left 4 Dead. Set during the aftermath of an apocalyptic pandemic, the game focuses on four new Survivors, fighting against hordes of zombies known as the Infected, who develop severe psychosis and act extremely aggressive. The Survivors must fight their way through five campaigns, interspersed with safe houses that act as checkpoints, with the goal of escape at each campaign's finale. The gameplay is procedurally altered by the "AI Director 2.0", which monitors the players' performance and adjusts the scenario to provide a dynamic challenge. Other new features include new types of Special Infected and an arsenal of melee weapons.[3]

The game made its world premiere at E3 2009 with a trailer during the Microsoft press event.[4] Prior to release, it received mixed critical and community reactions, and attracted an unusually high volume of controversy about its graphic content. In response, alterations were made to the cover art,[5][6] but both Australia and Germany refused to rate the unmodified edition at the time of release.[7] Despite this, the game was met with positive critical reviews, and is considered to be one of the greatest video games ever made.

Like its predecessor, Left 4 Dead 2 is a first-person shooter with a heavy emphasis on cooperative gameplay. The game presents five new campaigns, each composed of three to five smaller levels. As in the first game, each campaign is presented in menus and loading screens as a film starring the four Survivors; and features, upon completing a campaign, a faux credits screen which acts as the final scoreboard for the players and recaps certain performance statistics for the group. In every campaign, most levels involve the Survivors attempting to reach a safe room and close the door once they are all safely inside. However, the final level in each campaign 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 an escape vehicle, or collect and utilize fuel cans to enable their escape.[8][9]

To enable situational awareness of other Survivors, players are shown the health and status of their fellow survivors. If a player does not have direct sight of another Survivor (e.g. a wall is blocking their view of the others), they will be shown the Survivor's highlighted silhouette. The Survivors are also susceptible to friendly fire, forcing players to exercise caution when shooting or swinging their weapons.[13] As Survivors take damage, they move more slowly; if a Survivor's health drops to zero, they are incapacitated and left to fight off the Infected using a handgun until rescued by another Survivor. If a Survivor dies, they remain dead until the next level, unless revived by a defibrillator, or, in Campaign or Singleplayer mode, reappear in a "Rescue Closet" to be freed by other Survivors.[14] Should all Survivors die or be incapacitated, the game will end, at which point the players may restart that chapter or quit the game.

Left 4 Dead 2 also features a Realism mode, which can be enabled at any difficulty for either Campaign or Versus. This mode removes some of the video-game aspects from the gameplay: Survivors cannot see each other's silhouettes, and dead teammates can only be revived with defibrillators and will not respawn later in the level.[16] Weapons and other items will only glow when the player is within a few feet, forcing the players to search the levels more thoroughly. Headshots to enemies deal more damage, whereas limb or body shots require more shots.[17] In addition, the Witch enemy can kill any Survivor she would have normally incapacitated (on difficulties other than Easy). Designed to force players to work closely together and rely on voice communication, Valve created Realism mode to give players a way "to be challenged as a team" without having to increase the difficulty level of the game.[16]

Finally, in later versions of the game, there is a Mutation option, in which players can select from a menu of 30 variations, some singleplayer, some multiplayer (and some of the latter cooperative, some versus, or both). Each variation changes one or more major game dynamics, such as: constantly draining health, solo mode with no Survivor allies, death upon incapacitation, only one kind of weapon available, coop that later switches to versus, shooting or targeting constraints, an enemy type with increased power, increased numbers of Special Infected, etc. One of these modes, named GunBrain, is a weapons stats analyzer.

While also referred to as zombies, the Infected are humans who have contracted a mutated strain of an infection, though neither the source nor nature of this "Green Flu" are made clear in the games. The most numerous Infected encountered by the survivors are the common Infected. Though individually weak, they can swarm and overwhelm the Survivors, especially when separated from their teammates. Damage to the infected in Left 4 Dead 2 is portrayed more realistically, with bullets and melee weapons ripping off bits of flesh and, in some cases, limbs.[18] A new addition to Left 4 Dead 2 is the Uncommon Infected unique to each campaign. By virtue of location and equipment worn pre-infection, they possess abilities that separate them from the Common Infected. For example, the Dead Center campaign introduces infected CEDA agents in hazmat suits, making them fireproof;[19] Dark Carnival includes clowns, whose squeaking shoes attract small hordes of Common Infected;[20] and The Parish includes infected private security contractors in riot gear, making them bulletproof from the front.[21][22]

As in the first game, there are special Infected whose mutations grant them special abilities that make them highly dangerous, which act as bosses. The presence of such Infected nearby is hinted at by sound effects or musical cues unique to each type. The five Special Infected from the first game return in Left 4 Dead 2, some with modified behavior and skin models:

As in the first game, an artificial intelligence system called the AI Director drives gameplay by procedurally spawning enemies, weapons and items based on players' performance during any given campaign. In Left 4 Dead 2, the Director has been improved to encourage more participation by players, forcing players through difficult gauntlets to reach safety. It also has the ability to alter elements of the level, such as placement of walls, level layout, lighting, and weather conditions, making each play session unique.[3] The Director now rewards players for taking longer or more difficult paths through each episode by providing useful equipment, such as special ammo packs or higher tier weapons.[4]

Like its predecessor, Left 4 Dead 2 is set in the aftermath of a worldwide pandemic of a disease nicknamed the "Green Flu", which rapidly transforms humans into zombie-like creatures and mutated forms that demonstrate extreme aggression towards non-infected beings. A few humans are immune to the disease, while some of those who are infected have no symptoms. The Civil Emergency and Defense Agency (CEDA) and the U.S. military create safe zones to attempt to evacuate as many survivors as possible. Left 4 Dead 2 introduces four new survivors: Coach, Ellis, Nick, and Rochelle, who are immune to the disease and have individual backstories that are provided through character dialogue.[36][37][38] While the game is intended as a continuation of the original, occurring one week after the first game begins, Valve decided to create a new group of survivors due to the change in location.[39] Like the first game, the five campaigns in Left 4 Dead 2 take place across a story arc.[40] Set in the Deep South, the story begins in Savannah, Georgia, and ends in New Orleans, Louisiana.[3][4] The four survivors have to fight their way through hordes of infected, using safehouses along the way to rest and recuperate in order to reach extraction points.

Left 4 Dead 2 features a new cast of four human survivors: Coach (voiced by Chad L. Coleman), a stocky high school football coach with a bad knee (although this does not affect gameplay);[41][42] Nick (voiced by Canadian singer Hugh Dillon), a pessimistic gambler and con artist;[43][44] Rochelle (voiced by Rochelle Aytes), a low-level production assistant for a local television station that was reporting on the pandemic;[36][45] and Ellis (voiced by Eric Ladin), a friendly and talkative redneck mechanic[46] who often talks about his friend Keith and their many misadventures.[3][38] In addition to the four playable characters, Left 4 Dead 2 also features two supporting characters in the form of Whitaker (voiced by Dayton Callie),[47] a gun store owner, and Virgil (voiced by Randall Newsome), a Cajun boat captain who appears (voice only) in the game's final three campaigns. Two soldiers heard in the final map of The Parish, voiced by Bob Gunter and Bill Huggins, round out the NPC cast.

Left 4 Dead 2 opens in Dead Center (set in Savannah, Georgia), where the four survivors find themselves abandoned on a hotel roof by rescue helicopters. They decide to head for the local mall, where a second CEDA evacuation point is located.[51] After a brief encounter with a gun store owner, Whitaker,[47] the survivors discover that the mall is overrun, with all CEDA agents having become either dead or infected as well. Ellis helps the group use a stock car to break out of the mall[8] and travel towards New Orleans, rumored to be the last standing city in America.[52]

The Passing takes place between Dead Center and Dark Carnival, and after the events of The Sacrifice campaign. The survivors arrive at the bridge in Rayford, where they meet Francis, Louis, and Zoey.[53] As they need to cross the bridge to proceed, the Survivors need to find another way across to refill the generator with gas. After fighting their way through a wedding reception (complete with a Witch bride),[54] the streets, and a historic under-the-river tour,[55] they meet up again with the original survivors, who help by covering for the group while they fill the generator and lowering the bridge once it's full.[9]
