The Survivors

The Survivors are people in the world who have not yet contracted the infection, however the term is commonly used to refer to the four playable characters. Although they are immune, a comment by Bill suggests that they could become an Infected at any point. Fortunately, this does not happen during the game. It is never explained thus far how these people all have met each other, or how long they have been together before the start of the game.

Playable Survivors
Each playable Survivor has his or her own unique appearance, personality and backstory, making them easier to identify at a distance. Players can choose which Survivor they control in the lobby, or be automatically assigned to a Survivor that is not being controlled by a player when they join a game that is already in progress.

Every Survivor plays the same, their differences have no effect in gameplay.

Bill


Bill is a Vietnam veteran who served in the US Army 1st Special Forces Group. His combat skills have helped to keep him alive, he is also the oldest of the group. In official media, he is usually seen wielding the assault rifle, probably to complement his backstory. He and Francis have a strenuous relationship. He is voiced by Jim French. He always has a lit cigarette in his mouth, even upon death.

Francis


Francis is a large, tough biker with tattoos covering his arms and neck. His tattoos identify him as a member of "Hell's Legion", a name possibly inspired by the real-world Hell's Angels Motorcycle Club. Since his character model has changed, it has been speculated that Francis' new face was modeled after the head developer of the game, Mike Booth, and that he has the Lambda symbol from the Half-Life series cut into his hair. In the official media, he is usually seen wielding either the pump shotgun or the auto shotgun. He is voiced by Vince Valenzuela.

Louis


Louis is another of the four playable Survivors in Left 4 Dead. His original concept was an assistant manager at a local retail electronics chain store. His design was changed and he was made a Junior Systems Analyst in his company's IT department. His clothing resembles the typical business man, but bears a resemblance to Shaun from Shaun of the Dead, who wore a red tie and white shirt. In official media, he is usually seen wielding a submachine gun or dual pistols. He is voiced by Earl Alexander.

Zoey


Zoey is the teenage daughter of a wealthy family. Being in her first year of college would make her at least 18 (She could be older depending on what age she was when she entered college). She typically uses the rifle. Zoey's original design was based on Alesia Glidewell, who also worked with Valve on Portal as a model for the character Chell. However, when the character designs were updated later in development, Zoey was made to resemble actress Sonja Kinski instead. She is voiced by Jen Taylor.

Coach


Coach was a high-school football instructor for a well playing team, but he suffered a nasty knee injury. Ironically, he's now a health teacher pushing 40 years old, but he's gone to seed since his collegiate glory days. The zombie apocalypse makes him wish he'd watched his own fitness more closely. Faliszek says Coach has "a great hatred for a few of the zombies; the Witch in particular" but naturally, he wouldn't explain why. He appears to be Bill's replacement. Coach is voiced by Chad L. Coleman.

Ellis


Most people would be scared witless by the zombie outbreak. Not Ellis—he's 21 and indestructible, so there was no way he was getting infected. The Savannah native respects his mother, loves his job and enjoys the simple pleasures in life. A little cocky, it remains to be seen if the end of the world will show him fear for the first time. Ellis is voiced by Eric Ladin.

Nick


Nick is a gambler and a conman in a slick, expensive suit, and so takes the Louis role as the "business man" of the group. Nick joined the other three in their quest to find salvation but is unsure about whether or not he can trust them, often comparing them to The Three Stooges. Still trying to figure out the best "angle" to get from the recent zombie apocalypse, as the time goes by, he starts to value his Survivor compatriots. Nick is voiced by Hugh Dillon.

Rochelle


Rochelle is 26-years-old and comes from Cleveland. She likes to communicate with the world and therefore became an associate producer in journalism. She was recently promoted and was sent to Savannah, the location of the first campaign, to produce a story on the odd occurrences that were happening. Rochelle is voiced by Rochelle Aytes.

Anonymous Survivors
As well as the four playable Survivors, there are also known to be many more uninfected humans fighting the Infected and trying to escape the area that the four campaigns take place in. All except the chopper pilot remain unseen and most remain unnamed; however, they are evident by graffiti left around most of the chapters, mainly in the safe houses. The safe houses themselves are proof of other Survivors, as they are pre-created before the playable Survivors get to them, which implies other humans have created them to give other Survivors a place to rest and stock up on ammo. In some graffiti it is also stated that there were more Survivors who were immune. The only other Survivors you encounter are only spoken with, either through radio in an evacuation finale, or in the case of the "Church Guy" who locks you out of the safe room and tries to kill you by attracting a horde.

"Church guy"
A crazy man who can be found in chapter three of the Death Toll campaign, The Church. He appears to be afraid of Infection, barricading himself in the safe room that the Survivors must get through. It is later revealed that he was bitten by a survivor who claimed to be immune (to be allowed in), yet became an Infected; Church Guy deemed himself immune to the virus after waiting an hour. As a result he suffers from extreme paranoia of Survivors, and it has obviously driven him to insanity. Ultimately, he also becomes an Infected.

He repeatedly says "better safe than sorry" and causes a Crescendo Event where he rings the church bell to attract a horde to kill the Survivors. (He views this will "prove their immunity/humanity".) After the event, the safe-house door can be opened and a Special Infected will emerge, providing a conclusion to his change. You may hear him start to growl (Hunter), cough (Smoker), or gurgle (Boomer) before you open the door. After opening the door and ascending to the second floor of the safe room, the Survivors can see that the Church guy has written his motto all over a wall, over 180 times. His voice actor, Nathan Vetterlein, also voiced the Scout from Valve's Team Fortress 2.

The Survivor who infected him is male by the audio files. However, you can see a corpse of a female slumped against the wall in the safe room when you walk in. It does not appear to be a common infected, but a body that spawns there to set the mood like the dead soldiers on the roof of Mercy Hospital. However, this may be a slip up by the creators, or she could have been killed by biting him.

Despite ongoing rumors and popular belief of a slim chance of occurring, he will never turn into a Witch or a Tank after the crescendo event. If players were to examine the left4dead/scripts/population.txt file, it appears that there is a 50% chance of a Boomer appearing, and 25% each of either a Smoker or a Hunter appearing. No mention of the Tank or the Witch are included in this file, making it clear that there is no chance of the Church Guy becoming a Tank unless there is a serverside mod in use. Alteration of the population.txt file to force the Church Guy to transform into a Tank or Witch can create very strange results, thus verifying the fact that the Church Guy will never spawn as a Tank or Witch.

Evacuation Personnel
During the finale of each scenario, a Survivor in a vehicle must arrive to rescue the four main characters from their evacuation point. These Survivors are never seen, as they are usually concealed behind the windscreens of their vehicles, excluding the helicopter pilot from the No Mercy campaign. These Survivors include the aforementioned helicopter pilot from No Mercy, the boat drivers (John and Amanda Slater) from Death Toll, the C-130 pilot from Dead Air, and the APC driver from Blood Harvest. In all cases you communicate with them via radio. It also indicates more Survivors in Blood Harvest when contacting the driver of the APC. After you answer the radio, one of the radio communicators yells back to another one. One of the two is presumably the driver.

Each rescuer has separate motives for rescuing the Survivors:
 * The helicopter pilot appears to be affiliated with either the military or CEDA, regularly evacuating civilians to an unknown safe zone, however, since he flies the News Chopper 5, it can also be assumed he was a news reporter evacuating civilians out of good will, if this is the case he was part of a fairly large news network considering there are posters for the helicopter in The Subway. His voice actor is Dennis Bateman, who also voiced the Spy and Pyro in Team Fortress 2.
 * John and Amanda Slater (the boat pilots) are civilians hoping to gain additional firepower as they escape from Riverside. John's voice actor is John Patrick Lowrie, who voiced the Sniper in Team Fortress 2.
 * The C-130 pilot appears to be stranded at the airport due to a lack of fuel, refusing to leave his plane and expose himself to the infected. His voice actor is Gary Schwartz, who voiced the Heavy and Demoman in Team Fortress 2.
 * The APC driver in Blood Harvest is a member of the US Military who was ordered to evacuate the Survivors to an unknown, presumably northern safe zone. His voice actor is David Scully.

Below are the captions of quotes stored within the game files, but not actually heard or used within the game.

John Slater

 * "Hello? See Amanda, I told you someone was still out there!"

 * "So what, then? We leave 'em to die? I can't do that, Amanda."
 * "You know, I could come to my senses and start listenin' to my smart beautiful wife here."
 * "You know, we can hear you right now. You need to press the button again to get off the frequency."

Chicago Ted
Chicago Ted is an evidently egotistical Survivor, known for scrawling "No zombie is safe from Chicago Ted" on the wall of a safe room. Whether or not he's still alive is unknown. He presumably originates from Chicago, Illinois.

A recent interview shows that Chicago Ted may return in Left 4 Dead 2.

Virgil
A character appearing in Left 4 Dead 2. Little is known about him apart from the fact that he will be driving the escape boat in Swamp Fever and Hard Rain.

Distant Survivors
In the campaigns Dead Air, No Mercy, Crash Course, and sometimes at the end of The Town, occasionally, a distant gunshot, explosion, or gun burst may be heard. It can only be assumed that these are other Survivors fighting off the Infected. As they are infrequent, however, it is likely that few of them survive, or simply move out of hearing range. Not to say that none of them do, as, from The Sewer, looking very closely at the roof of Mercy Hospital in the distance, a white helicopter (different from the red, white, and blue chopper used by the survivors) can be seen flying in and out, hinting at more than one evacuation. The helicopter pilot will also sometimes comment to the Survivors, "Looks like you're gonna be my final run.", further indicating that he had been saving other Survivors from the rooftop. As this may be true, in Crash Course, Francis and Zoey fight constantly over the dead pilot. He can be heard saying he had an "incident" and it maybe he is trying to help you get away as far as he can before transforming into an infected. He seems aware that he is to die.

Trivia

 * The Survivors were changed from their original looks to the new look to make them appear like someone you may encounter in real life, to make them look more "realistic". Survivors in Left 4 Dead 2 started from this, but still, have changed from the first screenshots and videos (everyone but Nick).
 * It seems possible that each scenario is geared towards being the "home" of one of the four Survivors.
 * Bill makes a comment about the trailer in Blood Harvest, asking Francis if it reminded him of home, although this is most likely intended as an insult to Francis.
 * Louis seems to know somewhat trivial pieces of information involving the sewer system of Riverside.
 * Zoey said that she always liked the main street in Riverside, and also, in some early Left 4 Dead articles, she is referenced as being from a farm, indicating a possible relation to Blood Harvest. She also states that she has been to Newburg before.
 * Francis is surprisingly knowledgable about the area of Newberg near the airport, and seems to know his way around the airport itself.
 * Both Bill and Louis appear to know their way around Fairfield, knowing that the subway's Red Line heads straight to Mercy Hospital, and that it is possible to reach the hospital by going through the waterworks (which leads into the sewer).
 * Chicago Ted is a meme on Internet forums, assumed as being the best of the best in a zombie outbreak.
 * In the beta of Left 4 Dead, Zoey and Francis show some sort of affection towards each other, this proved to be too distracting, so it was removed.
 * The beta of Zoey looks like Chell from the popular Valve game Portal.
 * Chicago Ted's graffiti is based on a piece of graffiti found by Erik Wolpaw and Sean "Seanbaby" Reilly
 * The 3 male Survivors in Left 4 Dead 2 all bear resemblances to characters in the Dawn of the Dead remake; the Coach being Kenneth, Nick being Michael, and Ellis being Terry.
 * The helicopter pilot in the No Mercy campaign is the only Survivor that players can actually see alive in person (Not counting the "Church Guy" who is never actually witnessed until becoming Infected).
 * It is likely the original four Survivors will appear in Left 4 Dead 2 as they have expression files loaded into the pre-loaded files of the demo.
