The Survivors

"That's right, we should call ourselves the Unstoppables!"

- Louis "We're the four riders of the goddamn apocalypse!"

- Nick

The Survivors are people in the world who have not contracted the Infection (or are carriers of the disease). The term, however, is commonly used to refer to the eight playable characters from the Left 4 Dead game series. Although the playable characters are immune, a comment by Bill suggests that they could become an Infected at any point. In Left 4 Dead, it is never explained how they met up with each other, or how long they have been together. At the start of the first campaign in Left 4 Dead 2, the playable characters have just met each other and do not even know each other's names. There are also non-playable Survivors that players will meet throughout the campaigns.

Playable Survivors
Each playable Survivor has his or her own unique appearance, personality, and back-story, 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 are purely cosmetic and do not alter gameplay. When controlled as AI Bots, Survivors will have preference over specific weaponry, and will attempt to choose that type if possible.

Introduced in Left 4 Dead
NOTE: Left 4 Dead Survivors appear in The Passing for Left 4 Dead 2, but are unplayable characters. As the DLC The Sacrifice takes part in Left 4 Dead ' s storyarc, it will be possible to play as the Left 4 Dead Survivors in Left 4 Dead 2 due to the DLC being ported to Left 4 Dead 2 as well.

Bill


Bill is a Vietnam veteran who fought in the US Army 1st Special Forces Group. His combat skills have helped to keep him alive, and he is also the oldest of the group. He wears an olive green military beret, a matching jacket with a stained white shirt underneath, dark gray-brown pants, and jungle boots. In official media, he is usually seen wielding the Assault Rifle, and in-game, he prefers that weapon, probably to complement his back-story. He and Francis have a strenuous relationship, often spewing insults or jokes at one another, but these may or may not be friendlier than what they let on. He always has a lit cigarette in his mouth.

It is revealed in The Passing that Bill was killed prior to the bridge being raised during The Sacrifice, enabling the safety of the other Left 4 Dead Survivors. His body can be seen next to the generator in the final level of The Passing at the Port, alongside his signature Assault Rifle, which can be taken and used by the player.

Bill is voiced by Jim French.

Francis


Francis is a 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. He wears a black leather vest over a white tank top, fingerless gloves, black jeans and boots. In official media, he is usually seen wielding either the Pump Shotgun or the Auto Shotgun, and in-game, prefers those types of weapons.

Francis is voiced by Vince Valenzuela.

Louis


Louis' original concept was an assistant manager at a local retail electronics chain store. His design was later changed, and he was made a Junior Systems Analyst in his company's IT department. His clothing resembles the typical business man, but seems to emulate Shaun from Shaun of the Dead, who wore a red tie and white shirt, and was an assistant manager at a local retail electronics chain store. He keeps the sleeves rolled up and the tie loose, and also wears a black watch on his left wrist. In official media, he is usually seen wielding a Submachine Gun or dual Pistols. In-game, Louis prefers the Submachine Gun and Assault Rifle. At some point prior to The Passing, Louis was injured, rendering him unable to stand on his own. Because of this, he uses a Heavy Machine Gun at the Port.

Louis is voiced by Earl Alexander.

Zoey


Zoey is in her first year of college, which makes her at least 18 (she could be older depending on what age she was when she entered college). She wears a reddish-pink track jacket, blue jeans, converse shoes and keeps her hair tied up in a ponytail. Her 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/model Sonja Kinski instead. In official media, she is usually seen wielding dual Pistols. In-game, Zoey shows preference for the Hunting Rifle.

Zoey is voiced by Jen Taylor.

Coach


Coach is a Physical Education teacher at the local high school in the town of Savannah, where he originates from. Having sustained a knee injury in college which ended his prospective career as a defensive linesman, Coach took up teaching as a possible path for a pro coaching career. He wears a polo shirt in the yellow and purple colors of the high school he works at, fingerless gloves, beige slacks and gray sneakers. He is the oldest of the group and serves in an unofficial capacity as leader. In-game, he shows preference for Tier 1 and Tier 2 shotguns.

Coach is voiced by Chad L. Coleman.

Ellis


Ellis is a mechanic hailing from Savannah, similar to Coach. He wears a yellow t-shirt with a logo, a white and blue baseball cap, half-removed coveralls and black work boots. Ellis appears to have a lack of comprehension of the seriousness of his current situation and retains a somewhat goofy personality in comparison to the other Survivors. Ellis also has a love interest in Zoey when he first meets her in The Passing. In-game, Ellis has preference for the Sniper and Hunting Rifle.

Ellis is voiced by Eric Ladin.

Nick


Nick is a shady con man and gambler drifting from city to city, having got caught up in the current crisis throughout Savannah. He wears an expensive white suit with a blue button-down shirt underneath, several gold rings and white leather shoes. Nick holds a negative and pessimistic view of the situation along with the three strangers he's forced to work with, but learns to trust them over the course of the game. In-game, Nick shows preference over Submachine Gun and Assault Rifle variant weaponry.

Nick is voiced by Hugh Dillon.

Rochelle


Rochelle is a minor associate producer for an unknown news station with a high reputation, though her job had more to do with moving cables and coffee duties. She was in Savannah producing a segment about the evacuation center when the area became overrun with the Infected. She wears a pink t-shirt with a Depeche Mode logo, hoop earrings, blue jeans, a thin studded belt around her waist and knee-high brown boots. In-game, Rochelle has preferences similar to Nick; she prefers Submachine Gun and Assault Rifle variants.

Rochelle is voiced by Rochelle Aytes.

The Church Guy
"Better safe than sorry...better safe than sorry..."

- The Church Guy

The Church Guy is a mentally unstable man who can be found in chapter three of the Death Toll campaign, The Church. He is afraid of the 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, yet became an Infected; as a result he suffers from extreme paranoia of Survivors, and it has obviously driven him to insanity. After waiting for an hour, he assumes that he is immune. Ultimately, it turns out the Church Guy isn't immune after all; he will change into a Hunter, Smoker, or Boomer.

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, apparently viewing this as a way for them to "prove their immunity/humanity". After the event, the safe room door can be opened and a Special Infected will emerge, providing a conclusion to his change. The Infected he will change into can be foretold by listening to the Church Guy starting to growl (Hunter), cough (Smoker), or gurgle (Boomer) before the door is opened. 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, judging by the audio files. However, a corpse of a female slumped against the wall in the safe room can be seen; it does not appear to be a Common Infected, but a body that spawns 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. another possibilty is that due to his insanity he gets mistaken.

Despite ongoing rumors and popular belief of a slim chance of it 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 or Witch unless there is a server-side 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.

Whitaker
"Now I've barricaded myself on the roof with ample provisions... but in my haste, I forgot cola!"

- Whitaker

Whitaker is a 60-year-old man who owns a gun shop located in front of Liberty Mall in the Dead Center campaign. By the time the Survivors arrive at his gun store, he has already barricaded himself upstairs with large amounts of ammunition and provisions. When the Survivors enter his store, Whitaker contacts them over an intercom, offering to clear a roadblock that is preventing the Survivors from reaching the mall with a grenade launcher if they go to the nearby Save 4 Less supermarket and fetch him a six-pack of Cola. A Crescendo Event is triggered when the Survivors enter the supermarket, with the burglar alarm going off and summoning a Horde. After retrieving the Cola, Whitaker launches a grenade at the roadblock, destroying it and allowing the Survivors to continue to the mall. Originally, Whitaker was supposed to cover the Survivors with an unknown weapon, possibly the grenade launcher.

Note that the Fallen Survivor Uncommon Infected model uses an Infected version of his model.

Whitaker is very similar to Andy from'' Dawn of the Dead (2004). ''They are both apocalypse survivors who own a barricaded gun store across the street from a mall with heavy ammunition and lacking important supplies (food for Andy, Cola for Whitaker.).

Whitaker is voiced by Dayton Callie.

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 in No Mercy 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 simply a former news pilot 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, who voiced Sergeant Johnson in the Halo series.
 * The helicopter pilot in Dark Carnival is never directly contacted, but is presumably looking for survivors for the same reason the helicopter pilot in No Mercy was. They also share the same character model.
 * Virgil is a boat owner who presumably picks up the Survivors out of a combination of kindness, potential loneliness, and to utilize them to get fuel from the mainland.
 * The military helicopter pilot in The Parish has been tasked with orders to pull out of the mainland, with the Survivors being informed if they can make it to his location before he takes off, he'll transport them.

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

John Slater
John Slater is contacted in the end of the Death Toll campaign.
 * "Hello? See Amanda, I told you someone was still out there!"
 * "Yeah! Yeah...ok...Amanda. They're doing fine. Yes. Boy. Go..."
 * "They're not doing that well. Listen, if I had guns I could do the same thing."
 * "Great. Okay, okay, sweetie. Yeah. It's...okay."
 * "On our way. But let's be clear: once you get on this boat? Your job is keeping our asses alive."
 * " ...Guess that makes two of us..."
 * "You were against buying the boat too, Amanda."
 * "Your problem, Amanda, is that you don't think about the little guy!"
 * "We're not coming in with that Tank there. Take care of it or you're on your own."
 * "Almost there! Get ready. We don't want to sight-see when we get there."
 * "Amanda, goddammit, this needs to get done."
 * "Amanda, if the world is ending - well, then it's ending. Can't hurt to spend our last hours trying to do some good, eh?"
 * "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."
 * "You know, my wife's been making some very good points here. You want me to put her in charge?"
 * "Yeah, go ahead and weigh your hundreds of options."
 * "I don't want our first act of kindness to be our last"

Plane Pilot
The Plane Pilot is the one who get the survivors out of Newburg in the Dead Air campaign.
 * "Someone gonna help that oldtimer?"
 * "Man, that thing looks like my ex-wife! [Chuckles] Don't forget to tip yer waitress, I'll be here all week."
 * "Ain't nobody gonna help that pretty young thing?"
 * "Nobody gonna help that little girl?"
 * "Hey guys, I think suit and tie's down."
 * "Holy shit, lookit the size of that thing!"
 * "Man, I almost wish I was down there! That looks like fun!"
 * "Look out, folks. That sneaky zombie's around somewhere."
 * "Uh oh. You see where that sneaky guy went?"
 * "Hey, that big greasy fella's down!"
 * "Hey, Vest! Behind you!"
 * "Man! No offense, but I can't believe you guys're still alive right now!"
 * "I'd be out there with you if I didn't have all this pilot stuff to take care of!"
 * "That thing's jumpin' around like spit on a hot skillet!"
 * "Man, that thing's got a big tongue!"
 * "Yeah yeah yeah, I'm a coward for not helpin' ya. Guess I'll just sit up here in my cockpit, flyin' you out of this hellhole, like I flown everyone else who came here lookin' for help. But no, thank you for bein' honest!"
 * "You callin' me a coward? Get this straight! I can fly planes! You can run around gettin' killed! In a post-apocalyptic world, that makes me valuable and y'all worthless!"
 * "You sayin' I'm yellow? I been riskin' my life flying people outta this airport all goddamn day! Then the government dropped a bomb on me! So excuse me if I don't skip down there and pick a rifle!"
 * "Jesus crow, look at the size of that one!"
 * "Uh oh. Well, nothing wrong with a lighter load."
 * "Shit. Well, there's more room for the rest of us, I guess."
 * "Man. I bet that fellah works out."
 * "Looks like we just got an opening for first class."
 * "Hoo. Well, I guess the rest of us can stretch out in the plane now."
 * "Ohhhhhhh, shit. That is unfortunate."
 * "Huh! I thought your bacon was cooked for sure!"
 * "Uh oh! Fuel tank's leaking! Nah, just kidding!"
 * "Hooo! Bet you don't want to do that again!"
 * "Did you guys shoot that plane down?

Soldier
The Soldier picks up the Survivors in the end of the Blood Harvest campaign.

Due to some of the unused lines one could think the farmhouse was suposed to be blown up after the truck picked up the survivors.
 * "Sit back and enjoy the show. We can take it from here."
 * "Glad you made it. Why don't you sit back...and enjoy the show."
 * "We're gonna send these things back to Hell."
 * "BOOOOOM!"
 * "Ah ha ha ha! Yeah, baby!"
 * "Blow it up!"
 * "If you'll look slightly to your left...boom!"
 * "And to your right, boys...bam!"
 * "BOOM!"
 * "Now that's what I call a show!"
 * "Get on so we can get our asses out of here."
 * "The zombies are no more, BOOOOM!"
 * "Man, you guys are lucky to get here."

Virgil
"Now this is a'far as Virgil goes, but y'all can make it to the bridge from here."

- Virgil

A character appearing in Left 4 Dead 2 with a Cajun accent. He drives the escape boat in Swamp Fever, has the Survivors gather fuel on the mainland and return to the boat in Hard Rain, then drops off the Survivors at the beginning of The Parish. Virgil may be immune to the virus and is saving survivors out of good will, and to use them to gather fuel. He has become a widower after his wife was killed by an Infected bite, and will occasionally refer to himself in third-person. His boat is named the Lagniappe, a reference to the Louisiana custom of the same name, meaning a small gift given to a customer by a merchant at the time of a purchase.

There is a joke on the steam forums that states that Virgil is a talking boat. This "theory" is substantiated by Chet Falizak who stated that "Virgil is not a Man" when someone asked why Virgil existed during the "Last Man on Earth" Mutations http://img718.imageshack.us/i/capturefm.jpg/

Virgil is voiced by Randall Newsome

Papa Gator and Rescue 7
In the start of The Bridge in The Parish, two soldiers can be heard speaking over radio. They are known by their codenames "Papa Gator" and "Rescue 7". They arrange for the evacuation of the Survivors from New Orleans.


 * Papa Gator: Rescue 7 this is Papa Gator, over.
 * Rescue 7: This is Rescue 7, over.
 * Papa Gator: Rescue 7 what is your prepare stat? Over.
 * Rescue 7: Prepare ETA 10 minutes over.
 * Papa Gator: Did not copy, say again Rescue 7, over.
 * Rescue 7: Ten minutes, over.
 * Papa Gator: Copy that, all lambs extracted, last buzzard starts running in 15 minutes, copy that? Over.
 * Rescue 7: Roger that Papa Gator, 15 minutes. Ah, be advised, we have seen flashes on the west bank, ah... visually confirmed west bank is clear, over

 * Rescue 7: Ah-ffirmative, out.

Nondescript Survivors

 * See also: Graffiti

As well as the eight playable Survivors, there are also known to be many more uninfected humans fighting the Infected and trying to escape the area that the twelve campaigns take place in. All except the chopper pilot and Whitaker remain unseen and most are unnamed; however, they are evident by graffiti left around most of the chapters, mainly in the safe rooms. The safe rooms 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. Also, mostly in city chapters, gunfire can be heard in the background.

In some graffiti, it is also stated that there were more Survivors who were immune; whether they're immune or not, however, is not mentioned. The only other Survivors encountered are only spoken with, either through radio in an evacuation finale, or in the case of the "Church Guy", who locks the playable Survivors out of the safe room and tries to kill them by attracting a Horde.

Keith
A friend of Ellis'. He is often mentioned in stories Ellis tells while in a Safe Room. If Ellis' stories are to be believed, Keith has suffered from third-degree burns over a major percentage of his body twice (95% making fireworks, 90% deep frying turkey), lost two fingers and a thumb to frostbite, broke both of his legs after driving his car off a cliff, built a shack out of mud, been stabbed by a homeless man, got tear gassed by the police (the effects of which lasted for a year), snuck a paintball gun on a roller coaster, got attacked by an alligator, bombed by the military (among the bombs, Ellis claims, were nerve gas and cluster bombs), drowned in the Tunnel of Love, got cut up by his own "bumper-car" lawn mower leaving him with wounds over 90% of his body, got cement paved over him in a sewer after falling down an open manhole, lived in a graveyard for a year after getting kicked out of his house, hung spit on the overhang in the Tunnel of Love, fell off a roller coaster onto the tracks with the ride still going, got a tattoo on his forehead saying 'I'm a moron' for a dare, winning $200, ate three pounds of raw chicken (the in game subtitles say catfish) and lost sensation in his right foot doing so, turned a recreation of colonial times into a raccoon fight in his backyard, drove across a river without using the bridge, married a couple, and would have even gotten married himself, had he not ran away from his wedding.

It is possible he never existed in the first place, and Ellis simply made him up to make himself seem tougher, or just to pass the time and make friends with the other Survivors. It is likely that Valve simply added Keith as comedic relief in the serious game. At one point during Hard Rain, Ellis even confuses to the Survivors fighting their way through the burning hotel in Dead Center for something that happened to Keith. It is unknown if Keith is still alive and/or uninfected or even real. If Keith is real and is indeed alive, it is very possible and likely that he is fighting the Horde, seeing as so many incidents failed to kill him. However, in certain cut lines, Ellis claims he was the first on a helicopter. But, looking at how he's extremely unlucky but manages to survive, it's not likely that he's meeting any other Survivors or getting evacuated.

It is worth noting that a graffiti on the wall in The Subway reads as “Keith: Waited 3 days at the meeting spot after we got separated. I can’t wait anymore. Meet me at Mercy Hospital – Krista". However this could just be a coincidence, seeing as Keith is a relatively common name and is unlikely a person would travel all the way from Georgia to Pennsylvania, which happens to be the very place where the Infection broke out, just to get rescued.

After contacting Gabe Newell, asking if Keith is actually real, he answered saying "Keith isn’t imaginary, except, well, it is a video game, so it’s all imaginary."

A full listing of stories concerning Keith by Ellis can be found here.

Ray
Ray was a fellow co-worker and possible friend of Left 4 Dead Survivor Louis at a business called "Franklin Brothers" in Philadelphia PA, until the second day after the first Infection. During the second day Ray decides to call out of work sick much to Louis's dismay, claiming he does not want to go to work because of the rapidly spreading infection and would rather stay home from work then risk getting exposed to the Green Flu. His status is unknown and will presumably be revealed within the four-part upcoming comic.

Distant Survivors
In the campaigns Dead Air, No Mercy, Crash Course, and sometimes at the end of The Town (as well as the main menu), 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 survived, or simply moved 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 that 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 going to die. He was going to be in the game, or at least the sound files were, but what he said during Infection left players with a bitter taste after their victory, so his audio files were never introduced into the game when it was first released. The audio clips do activate with the Crash Course DLC installed, however.

It should also be noted that the pilot's model seems to be in Left 4 Dead 2 taking the Survivors from the finale of Dark Carnival and eventually crashing, as in Crash Course.
