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.

A far simpler version of the A. Director was previously used for some key battles in Half-Life 2: Episode Two. Valve is looking for ways to apply the Director in their future games to make pacing and difficulty more dynamic. Left 4 Dead contains four game modes: campaign, versus, survival, and single-player.

Additional Information

The cooperative campaign consists of up to four human-controlled survivors who attempt to make their way between safe rooms and eventually to rescue. In this mode, the special infected are controlled by the AI. In a versus campaign, each team of one to four players plays each chapter of the campaign as both survivor and infected, swapping sides once per chapter. If at least one player-controlled survivor finishes the level, the survivor team earns points as well as bonus points based on their health and the health items in their inventory.

These points are then multiplied by the chapter's difficulty level, and the number of survivors who finished. If all player-controlled survivors are killed, the survivor team only earns points according to their average progress through the chapter and the difficulty multiplier. On Xbox , other players can join in on the same console to turn single player into an offline co-op game. The game can also be played through a system link, or local area network. Players have also discovered a way to do splitscreen co-op play with the PC version. Development on Left 4 Dead started in mid A teaser was released with The Orange Box.

Turtle Rock Studios announced Left 4 Dead on November 20, , [28] and was acquired by Valve Corporation on January 10, , because of the game and long-standing relationship between the companies. Valve also hosted photo contests called, "Dude, where's my thumb? Left 4 Dead uses the 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.

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. 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. Left 4 Dead underwent many phases of development; influenced by playtesting , Turtle Rock Studios removed many of the features that were originally in the game.

In the initial phases, there was another special infected, called the "screamer", which 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 infected class was removed, but its ability to attract the horde was incorporated into the boomer's vomit. This would provide a score to rank a player's effectiveness as a teammate, [39] 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 long introduction 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. 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.

To promote the game and provide basic training to players before starting the game, Valve chose to develop a pre-rendered intro movie. This movie was released on Halloween [49] and shows events prior to the beginning of the "No Mercy" campaign. 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 to the final result for the launch of the game. Early access to the Left 4 Dead demo for people who pre-ordered the game began on November 6, , for both Windows and Xbox 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 ten percent savings for those who pre-order and applies to all Steam Windows pre-orders and all Windows and Xbox pre-orders from GameStop and EB Games in North America. 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. On May 1, , the game was released freely via Steam as a one-day trial called "Freaky Free Friday". The trial was then extended to end on Saturday.

Left 4 Dead went gold on November 13, , and was released on November 18, , in North America ; and on November 21, , in Europe to coincide with the tenth anniversary of the release of Half-Life. Valve released a server patch in December to stop players on Xbox Live from using PC-style cheats. On February 5, , Valve released details about the upcoming downloadable content pack.

The two full campaigns of "Death Toll" and "Dead Air" for versus mode—which were previously unavailable—are included, as well as the survival game mode, where the survivors try to survive endless waves of the infected for as long as possible. On February 11, , Valve announced that the downloadable content for the game would be free for both the Xbox and PC; [62] and on April 21, it was released. This included a new set of plugins that allowed for users to import data from SketchUp , a free 3D modeling program, directly into the Hammer level editor for use in maps.

The update included a command line tool for packaging custom Left 4 Dead campaigns to ease distribution. A sequel, announced at the E3 conference and was released November 17, It contains a new campaign called Crash Course , set shortly after the events of the No Mercy campaign, where the Survivors try to get to a Truck Depot after the helicopter they were in crashed. It is available for co-op, versus and survival modes, with various tweaks to game mechanics, and containing new locations and character dialog. The price was amended soon after, and all players who bought the DLC at the higher price were refunded.

On November 9, , a matchmaking update to allow for matchmaking between teams of four players in versus mode was released. An add-on campaign for Left 4 Dead 2 , "The Passing", featured the Left 4 Dead survivors meeting the new cast as part of a full campaign. The Left 4 Dead 2 content was set for release in March , however it was delayed until April 22, To connect the events in "The Passing" to that in Left 4 Dead , Valve released another add-on in October for both Left 4 Dead and its sequel, entitled "The Sacrifice"; the events of the add-on take place before "The Passing" and tells how the Left 4 Dead survivors come to encounter the group from Left 4 Dead 2 , and how one sacrificed themselves for the safety of the others.

Valve announced a page digital comic that has been revealed in four parts in the weeks leading up to the release of The Sacrifice.

The comic begins with Bill, having just sacrificed himself to save the others, taking on three tanks while severely wounded. It then cuts to the finale of Blood Harvest, which is revealed to be one week earlier.

Overkill Software, the developers of Payday: The Heist , a similar game to Left 4 Dead featuring four player co-operative gameplay, announced in June that it has worked with Valve to create a DLC level for Payday in the form of a map mirroring the "No Mercy" level from Left 4 Dead , however, this DLC level is not canon to Left 4 Dead and does not lead to the infection that initiated the events in Left 4 Dead.

PC Gamer. Retrieved January 20, Big Download. December 2, Retrieved December 10, Archived from the original on September 9, Retrieved November 22, The events are trying to give them a sense of narrative. 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. Tim Larkin : We took several steps to keep the music interesting enough that the players would be inclined to keep it on as they play. 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. Retrieved July 5, The AI director—I don't want to say it fell out of Half-Life 2, but it was definitely a jumping-off point of stuff we did in Half-Life 2, particularly Episode 2. There are a couple of key battles where the number of Combine, and where they come at you from, uses something like that.

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.
