Left 4 Dead is a co-operative, survival horror, first-person shooter video game. It was developed by Turtle Rock Studios, which was purchased by the Valve Corporation part-way into development. The game uses the Source game engine, and is available for Windows-based personal computers and the Xbox 360. The best player known in the game is called "NofxBarn"

The game pits four Survivors of an apocalyptic pandemic against hordes of aggressive zombies. There are two game modes: a four-player, co-op Campaign mode, and an eight-player Versus mode. In both modes, an AI, dubbed "The Director", controls level pacing and item spawns, in an attempt to create a dynamic experience and increase replay value.

The game went gold on November 13, 2008, and was released on November 18, 2008 in the United States; and on November 21, 2008 in Europe to coincide with the tenth anniversary of the release of Half-Life.[1][2] A five-minute trailer was released on Halloween.[3] A playable demo was made available on November 6 for pre-purchasers and on November 11 for the general public, and was closed on November 18, 2008. The demo contained the majority of the first two chapters in the "No Mercy" campaign, and was playable in both single and multi-player co-op.

Left 4 Dead was well received with an aggregate score of 88% on Game Rankings and 89% on Metacritic upon its release, with praise given for its replay value, focus on cooperative play, and movie-like experience. Similar to Team Fortress 2, Valve intends to support the game with downloadable content.[4]

Gameplay

In Left 4 Dead, four Survivors must fight off infected humans while trying to escape or make their way to a safe house.

Left 4 Dead is a first-person shooter but makes use of the third-person perspective during certain events or player actions. In Campaign and Single-player mode, the player takes control of one of the Survivors; if four human players are not available, then the remaining Survivors are AI-controlled bots. They play through the levels fighting off the "Infected"—living humans who have been infected with a mutated rabies virus to which the Survivors are immune.[5]

The game is focused on cooperation and team play; colored outlines of teammates are visible through walls to help players stick together and coordinate their movement. If a Survivor falls off a ledge, then they may automatically hang onto it and can only be helped up by another Survivor. If a Survivor's health is depleted, then they become incapacitated and can only be revived by another Survivor, at which point they continue playing with a low amount of health that decreases over time. If a Survivor has been incapacitated and revived twice without tending to their wounds, then they will experience distorted black-and-white vision, and the next incapacitation will kill the player. If a Survivor incurs enough damage while incapacitated, or is not eventually helped up by teammates, then the incapacitated player will die. If a Survivor is killed, then they will respawn in a closet or other enclosed space after a period of time (except during key points in the scenario or in Versus mode), but must be freed by another Survivor to rejoin the team. Otherwise, the player must wait until the next level.[6] Survivors can share first-aid kits and pain pills and help each other heal. Left 4 Dead has friendly fire that cannot be disabled, increasing the need for caution around other Survivors. On the Easy difficulty level, friendly fire does not harm teammates but still registers as having occurred.

The Survivors communicate by voice commands that are accessed by quick menus, and some sound off automatically when performing actions such as reloading or spotting Infected.[7] Over 1000 unique lines have been recorded for each Survivor.[8] Additional communication of player actions is conveyed through character lights. Also, weapon-mounted flashlights and muzzle flashes help the players in determining whether their companions are shooting, performing melee attacks, reloading or moving. Due to control issues and the likelihood of players using a LIVE headset, the Xbox 360 version of Left 4 Dead omits the quick phrases feature.[9]

The game is experienced through four campaigns that take place in various urban and rural locales. Multiple visual in-game hints, including license plates, park signs, and markings on airport equipment, imply that these locations are in Pennsylvania. Each campaign is divided into several chapters marked by safe rooms, which are checkpoints where players can heal, re-arm, and revive players who were killed.[10] Specifically, the four campaigns are: "No Mercy", an urban setting; "Death Toll", a small-town and countryside setting; "Dead Air", an airport setting; and "Blood Harvest", a woodland and farm setting. The levels are essentially linear, with distinct beginnings and ends, but there are a number of alternate routes to follow with more supplies, helping to create a sense of non-linearity.[11] In the final chapter of each campaign, the players must defend a position from an onslaught of Infected until rescue arrives.[8] Each campaign typically lasts between 45 and 75 minutes depending on the difficulty level.[12]

Survivor characters

There are four playable human characters in the game:[13] Francis (voiced by Vince Valenzuela), a tattoo-covered biker; Zoey (voiced by Jen Taylor), a college student and horror movie enthusiast; Louis (voiced by Earl Alexander), a Junior Systems Analyst in his company's IT department; and Bill (voiced by Jim French), a former Green Beret and a Vietnam veteran. Early plans were for players to be randomly assigned to characters but in the final release, players can choose any character—provided that the character has not already been selected—or be randomly assigned an unselected character.[8]

Survivors are armed with various firearms. Each player starts the game with a M1911 pistol.[14] It has unlimited ammo and is the only weapon that the Survivor can use when they are incapacitated. When a second pistol is found, the player can dual wield them. Regardless of what weapon a player is using, a melee attack can be used. At the beginning of each campaign, the player can choose between an Uzi submachine gun and a pump-action shotgun. As the Survivors progress through a campaign, more powerful weapons can be found: the M16A3 assault rifle, Benelli M4 Super 90 combat shotgun, and Ruger Mini-14 rifle. In addition to firearms, a player can also carry three other items in their inventory: improvised grenades (either a Molotov cocktail to create a wall of fire or a modified pipe bomb designed to attract the Infected to it, with a blinking light and alarm attached to it[14]); a first-aid kit, which heals the Survivor on which it is used; and pain pills, which provide temporary health and can be handed to teammates for later use. Also available are environmental weapons, such as gasoline cans, oxygen cylinders, and LPG tanks, that explode when shot. These can be picked up and moved by the survivors, however while carrying an object they cannot use their pistols or primary weapons.

Infected characters

The "Infected" are the Survivors' foes in Left 4 Dead, and they appear to be partly inspired by the infected from several modern films, including 28 Days Later.[15] The Common Infected encountered during the game are fast and agile, weak individually, but may be overwhelming in numbers. They occasionally attack en masse, referred to in game as a "Horde".[16] In addition to the Common Infected, there are five "Special Infected" whose mutations grant them special attacks that make them much more dangerous: the Hunter, an agile Infected that can pounce on Survivors from a great distance; the Smoker, an Infected that ensnares Survivors with its long tongue at a distance and, upon death, releases a cloud of smoke; the Boomer, a bloated Infected whose vomit and bile (which may be released at will or upon death) blind the player and attract the Horde; the Tank, a huge, muscular Infected that is the most powerful and difficult to kill; and the Witch, a passive female Infected that, when provoked by a loud sound, light, gunshots, or a Survivor approaching too close to her, will attack her provoker.[17] The victims of some of these attacks require assistance from a teammate before they can regain control. Each of the Special Infected, as well as approaching Hordes, have a distinctive sound or a timely musical cue, making their presence easily recognizable by players.[16]

AI and the Director

File:Left 4 Dead Director Intensity.jpg
In Left 4 Dead, the AI Director computes each player's "stress level" based on a variety of factors to better pace the game and provide a more even challenge.

The artificial intelligence of Left 4 Dead features a dynamic system for game dramatics, pacing, and difficulty called "The Director." Instead of fixed spawn points for enemies, the Director places enemies and items in varying positions and quantities based upon each player's current situation, status, skill and location, creating a new experience for each play through.[8] The Director also creates mood and tension with emotional cues, such as visual effects, dynamic music, and character communication.[9] Valve has termed this dynamic set-up "procedural narrative."[18]

In addition to the AI Director, there is a second Director that controls music. It was created as a way to keep the music interesting throughout the game. The music Director monitors what a player has experienced to create an appropriate mix. The process is client-side and done by a multi-track system. Each player hears their own mix, which is being generated as they play through the game, and dead players watching a teammate hear their teammates' mix.[19]

Versus mode

In Versus mode, four additional players can take control of the Special Infected (apart from the Witch, which remains computer-controlled), which are randomly assigned to them each time they spawn. While in Spawn Mode, Infected players can quickly roam around the map in search of an appropriate place to spawn. This location must be at a certain distance from any Survivor, must be out of the line of sight of any Survivor, and must be outside restricted areas such as safe rooms. When a "Tank"—the strongest Infected—is about to spawn, Infected players receive a message indicating which player will control it. The Infected have the ability to see Survivors through the walls every time a Survivor runs, talks, or fires a weapon—a Survivor who remains quiet by crouching or walking instead of running gradually fades from the Infected's vision. The Infected can also see in the dark, unlike the Survivors. Vertical pathways exclusive to the Infected are marked with symbols for the Infected players. These can be climbed and used for ambushes, especially with the Infected's immunity to falling damage. Versus mode is only playable in the "No Mercy" and "Blood Harvest" campaigns.

Throughout a Versus campaign, each group of four players plays each chapter of the campaign as both Survivor and Infected, swapping sides once per chapter. At the end of each chapter, the team playing the Survivors earns points based on how well they performed, multiplied by the chapter's difficulty level and how many Survivors reached the safe room. If all of the Survivors die before they reach the safe room, then the team is awarded points according to the average distance traveled to the safe room.

History

Development on Left 4 Dead started in mid-2005.[20] Valve aimed to create a horror film-inspired game that merges single player games' character-driven narrative structure with multiplayer games' social interaction and high replayability.[9] The game was first revealed in the Christmas 2006 publication of PC Gamer UK with a six-page article describing a playthrough at Valve's headquarters. A teaser was released with The Orange Box. The game was first playable at the Showdown 2007 LAN in San Jose and at QuakeCon 2007. Turtle Rock Studios announced Left 4 Dead on November 20, 2006,[21] and was acquired by Valve Corporation on January 10, 2008 because of the game and long-standing relationship between the companies.[22] The game opened up to pre-purchasing on Valve's Steam system on October 15, 2008.[23]

To give Left 4 Dead significant exposure, Valve financed a $10-million marketing campaign for the game in the United States and Europe, with advertisements appearing on television, print, websites and outdoor placements in many cities. Valve also hosted photo contests called "Dude, where's my thumb?" offering copies of Left 4 Dead to people who submitted the best picture involving zombies or the outdoor advertising.[24]

When asked a short while after the release of the game about the planned availability of a Source development kit (Level editor for Valve's Source game engine) for Left 4 Dead, Chet Faliszek from Valve replied that it was planned shortly.[25]

Development

Left 4 Dead uses the latest version of Valve's Source engine, with improvements such as multi-core processor support and physics-based animation to more realistically portray hair and clothing, and to improve physics interaction with enemies when shot or shoved in different body parts.[26] Animation was also improved to allow characters to lean realistically when moving in curved paths. Rendering and artificial intelligence were scaled up to allow for a greater number of enemies who can navigate the world in better ways, such as climbing, jumping or breaking obstacles.[27][28] Lighting was enhanced with new self-shadowing normal mapping and advanced shadow rendering that is important to convey information about the environment and player actions.[29][9] Wet surfaces and fog are used to create mood.[30][31] Many kinds of post processing cinematic visual effects inspired by horror movies have been added to the game. There is dynamic color correction that accentuates details based on importance, contrast and sharpening to focus attention on critical areas, film grain to expose details or imply details in dark areas, and vignetting to evoke tension and a horror-film look.[9]

File:L4d filmic.jpg
Before and after the application of cinematic effects

Left 4 Dead underwent many phases of development; influenced by playtesting, Valve removed many of the features that were originally in the game. In the initial phases, there was another Boss Infected called the "Screamer" who had no attacks, but upon spotting a Survivor would run to a safe place and then emit a loud scream that attracted a Horde of Infected. This Boss Infected was removed, but its ability to attract the Horde was incorporated into the Boomer's vomit.[32] A persistent merit/demerit system was envisioned to provide positive feedback for good behavior, such as aiding a fallen teammate; and negative feedback for poor behavior, such as shooting a teammate. This would provide a score to rank a player's effectiveness as a teammate,[33] but this system was removed late in the development of the game in favor of immediate, non-persistent feedback displayed in-game. Another significant element removed was a continuous narrative between campaigns; because the game is designed for replayability, it was difficult to hold the player's attention for repeated viewings of cut scenes, so they were dropped in favor of a sparse narrative.[34]

Certain Affinity assisted Valve with the Xbox 360 version of the game.[35] The Xbox 360 version of Left 4 Dead has the same game modes as the PC version but has additional features such as support for Split screen, allowing for two players to play offline and online from the same console,[36] and System Link play.[37] Both versions of the game have a new matchmaking system to simplify the process of finding other players.[38][9] This new server management system was met with a negative reaction from PC server operators, who, with this system, had very little control over their servers. This led to Valve releasing a series of patches that allowed server operators to remove their server from the matchmaking "pool" of servers or make private servers.[39] Valve runs dedicated servers for both versions of the game.[36][40]

Demo

Early access to the Left 4 Dead demo for people who pre-ordered the game began Thursday, November 6, 2008 on both Windows and Xbox 360. It gave users access to both online and single-player play in two "scenes" in one "movie" within the game. This promotion was being offered in addition to the 10% savings for those who pre-order and applies to all Steam Windows pre-orders and all Windows and Xbox 360 pre-orders from GameStop and EB Games in North America.

On November 11, the Left 4 Dead demo was made available to all Windows and Xbox 360 gamers worldwide. The demo concluded on November 18, when Left 4 Dead was made available at retail outlets across North America and worldwide via Steam, in order to use the dedicated servers for the full game.

The demo had many server problems when it launched, primarily Valve's strategy for server management which made it impossible to set up a dedicated private server with administrator controls.[41] However, a stream of patches led to the availability of a server browser and basic private server functionality as well as Valve's acknowledgment of player concerns.[41] It appears that a patch released just before the game itself has resolved many of the connection issues that demo players were having.[42]

Intro movie

To promote the game and provide basic training to player before starting the game, Valve chose to develop a pre-rendered intro movie. This movie shows events prior to the beginning of the "No Mercy" campaign.[43] Valve chose an intro movie over traditional in-game training mechanics because they wanted the players to be immediately dropped into a zombie apocalypse. Valve later detailed in their official Left 4 Dead blog how they designed the movie, from an intentionally very basic animation in the beginning of July 2008 to the final result for the launch of the game.[43]

After release

Similar to Team Fortress 2, Valve intends to support the PC and 360 version of the game through free content updates.[4]

On a podcast by Kotaku, writer Chet Faliszek divulged that an announcement regarding DLC for the PC and Xbox 360 would be released very soon, and that the announcement was delayed by the holiday season.

Reception

Left 4 Dead received almost unanimous praise from critics, with an aggregated score of 88% on Game Rankings and 89% on Metacritic. IGN stated that "It's almost pitch perfect in how it captures the tension and the action of a Hollywood zombie movie" and went on to describe it as "quite possibly the perfect co-op shooter."[45] Giant Bomb commented that the Source engine was beginning to show its age but praised the game's use of lighting and filmic effects that give the game world "a desolate, washed-out feeling," as well as the realistic and emotive faces and the engrossing art direction.[54] Eurogamer concluded that Left 4 Dead "is another deeply professional, personality-filled and progressive take on the shooter from Valve."[44] Both IGN and Gamespot praised the game's replayability, but Gamespot criticized the "limited map selection" that could "sometimes feel a bit repetitious."[46][45] Gamespy noted the lack of an overall narrative between the campaigns was disappointing[47] however some reviewers praised its faithfulness to the zombie film genre,[55][56][57] including the "deliberately ambiguous back-story",[58] and the amount of characterization and emotion brought by each of the four survivors.[59] TeamXbox commented that clipping issues hurt the otherwise "incredibly good" visual experience.[48]

On October 28, 2008, Valve reported that preorders for Left 4 Dead had beaten those of The Orange Box by 95% after the Steam pre-order was launched.[60] On November 21, 2008, the day of the game's release in Europe, Valve issued a press release stating that Left 4 Dead had exceeded the pre-order numbers of The Orange Box by over 160%.[61]

Awards

Left 4 Dead won several awards from various publications and gaming authorities. X-Play awarded it the best shooter for 2008. IGN gave both the PC[62] and Xbox 360[63] version the Best Online Multiplayer Game of 2008 award and additionally gave the PC version awards for Best Use of Sound[64] and Best Shooting game.[65] Left 4 Dead also won awards from Gamespy for the Best Multiplayer Game of the Year[66] and Spike TV for Best Multiplayer and PC game.[67] bit-tech awarded Left 4 Dead PC Game of the Year 2008.[68] Left 4 Dead won several 2008 awards from the French site NoFrag: The Father of All FPS, and Best Multiplayer.[69]

We look at sequences of events and try to take what their actions are to generate new sequences. If they've been particularly challenged by one kind of creature then we can use that information to make decisions about how we use that creature in subsequent encounters. This is what makes procedural narrative more of a story-telling device than, say, a simple difficulty mechanism.

We keep it changing so it won't become tedious; to this end, we created a music director that runs alongside the AI director, tracking the player's experience rather than their emotional state. We keep the music appropriate to each player's situation and highly personalized. The music engine in Left 4 Dead has a complete client-side, multi-track system per player that is completely unique to that player and can even be monitored by the spectators. Since some of the fun of Left 4 Dead is watching your friends when you're dead, we thought it was important to hear their personal soundtrack as well. This feature is unique to Left 4 Dead.

Miles Estes: Since killing zombies is such a big part of this game, we invested a lot of time into making their death animations more dramatic than simple ragdolls. We had a professional stuntman on the motion capture stage perform about a hundred different dying animations from different kinds of weapons and hit from different directions, like from the front or behind. We then combined these mo-cap animations with the physics-driven ragdolls.

Phil Robb: We treat the Infected Horde as a major character in Left 4 Dead, and spend a lot of effort in making their movements believable. This includes hundreds of motion-captured animations that are algorithmically blended with the physics system to create characters that realistically interact with their environment and each other. ... When they see a Survivor, they become enraged, taking off at a full sprint, leaning into their turns, jumping and climbing over everything in their way, trying to get to their victim. We wanted to express this rage in their faces as well, so we found efficient ways for each member of the Horde to make intense facial expressions.

Matt Campbell: Although it sounds ridiculous to talk about advanced zombie AI, we spent a great deal of time on the AI systems for the common Horde. First and foremost is their ability to navigate. The environments in Left 4 Dead are geometrically complex, and littered with breakable and movable objects. One of the design goals for the zombie Horde was that there can never be a place where a Survivor can stand that a zombie cannot navigate to. To make this happen required not only robust path-finding code, but also path-following algorithms as well. These path followers have to continuously evaluate the local geometry around them, and decide whether to crouch, stand, jump, climb over, and otherwise navigate nearly-arbitrary environmental obstacles.

The trick to the Screamer was that if he saw you, you had a moment to kill him before he ran away, and once the Screamer got away from the Survivors to a hiding place, he would emit a loud, howling scream that would cause a huge mob of zombies to attack the Survivors. While there were several exciting moments of knowing you had to chase him down to shoot him before he screamed, dodging zombies all the way, ultimately it proved too confusing for the Survivors to discover how he worked or even to reliably notice him in the crowd. He was cut, and his Horde-drawing attack eventually evolved into the Boomer attack.
