NPCs

Among the characters involved with the Left 4 Dead series, there are a number of Non-Playable Characters that help the Survivors along the way, or in some cases, don't help. Often they are either a road block forcing a Crescendo Event or they are a good Samaritan providing the Survivors with a ride to safety. Most of these characters are dead, either from becoming Infected[most evac personnel] or mauled to death[most of the comic characters], presumed dead as they're never seen again, or surviving within the apocalypse[Virgil, Whitaker].

In-Game characters
These characters are encountered withing both the PC and Xbox 360 versions of the Left 4 Dead series

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 possibility 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. Some think it may be a Rocket Launcher due to the different sound effect than a Grenade Launcher when shot. 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.

News 5 Chopper Pilot
The Chopper pilot is seen in the intro video to Left 4 Dead, and in the start of No Mercy he tells anyone who can hear him to precede to Mercy Hospital where they can contact him with a radio and he will pick them up and bring them to an unknown location. During the rescue at the top of Mercy Hospital, he will engage in communication with the Survivors, where he will reveal he had a 'incident', implying he attempted another rescue earlier but was attacked by the Infected.

Unfortunately for the Survivors who are rescued and taken to apparent safety, the pilot is infected, turns into an Infected mid-flight, and is shot by Zoey, forcing a crash landing.

John and Amanda Slater
John Slater is contacted in the end of the Death Toll campaign. He and his wife pick up the Survivors in their boat and get them away from Riverside. According to the comic, the Survivors were later thrown off the boat and left to die. The reason for this is unknown. Given that the owners specifically mention they will only rescue armed survivors, it's possible they only do so to rob them, explaining why the four once again only have basic weapons in the next campaign. Francis mentions the Slaters' marriage is troubled. Also, the Survivors are presumed Carriers in the Comic. If this is so, then they may have Infected John and Amanda unintentionally, but their resistance held out until after they kicked the original Survivors off the boat or they may be Immune/Carriers too.

Plane Pilot
The plane pilot evacuates the Survivors out of Newburg in the Dead Air campaign. In the comic, Francis mentions the plane later crashed. It is unknown why this happened or what became of the pilot.

Rescue 9
Rescue 9 is not just one person, but a platoon of soldiers, who respond to the Survivors when they communicate via radio. Rescue 9 sends out an Armored Personnel Carrier to pick up the Survivors at the end of the Blood Harvest campaign. The Sacrifice comic reveals Rescue 9 brought the Survivors to Millhaven instead of the Echo Safe Zone, in order to find a cure to the Infection. In addition, the comic reveals one of the soldiers in the APC was Lt. Mora, who personally drove so he could witness the Infected for himself.

Due to some of the unused lines one could think the farmhouse was supposed to be blown up after the truck picked up the survivors.

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 Faliszek who stated that "Virgil is not a Man" when someone asked why Virgil existed during the "Last Man on Earth" Mutations.

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.

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 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.

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.

The Midnight Riders

 * See main article: Midnight Riders

The Midnight Riders are a Southern rock band who were supposed to play in Whispering Oaks Amusement park but due to the Infection they had to cancel, so they were picked up by a helicopter, their status is unknown but the pilot was fine (by that time) so one can assume they were when they were dropped off. They are mentioned several times throughout Dark Carnival but never encountered, though one can occasionally see their tour bus speeding by in The Underground.

They have their own webpage which can be found here. http://www.midnight-riders.com/

Survivors from The Sacrifice comic
The following characters are only encountered within the Left 4 Dead comic released with The Sacrifice

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 much to Louis' 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 fate is unknown.



Wade and Carolyn
Wade and Carolyn are Zoey's parents, who are either divorced or separated. Zoey was living with her father at an apartment near her college for one semester, while Carolyn lives at their family home with a man named Kevin. Her mother is upset that she wants to quit college after just one semester, while her father is more easy-going and thinks she would do well in the family business in the police force. Unfortunately Carolyn is bitten by an intruder, turns into an Infected and ends up biting Wade, who shoots Carolyn when she goes after Zoey. Wade reminds Zoey of all the zombie films they watched when she was younger where the protagonists have to shoot someone before they turned, implying Zoey would have to shoot him, which she does after their final words of love with each other. Zoey is horrified to learn later on that her father may have been a Carrier, which may have meant he was immune to turning into an Infected, making her mercy-killing pointless.

Sandra
Sandra is Francis' ex-girlfriend that was at a bar with Francis and his friends. Unfortunately she ends up becoming infected when her and Francis are kissing in a back room at the bar after puking on his vest and biting his neck. She goes to finish him off but is shot by Francis' friend Duke. It should be noted that her figure after becoming infected bears resemblance to a Witch. However, she pounces at Francis and is easily dispatched by a shotgun shell to the torso, so it is unlikely that she actually was a Witch.

Duke
Duke is a friend of Francis, when Francis's girlfriend turned into a zombie and Francis didn't realize what was happening to her, Duke shot and killed her with a shotgun. Duke is wearing a Midnight Riders t-shirt and appear to believe in government conspiracies, stating that heroin, satellites and cell phones somehow was always meant to lead up to the zombie apocalypse. It is not known if he is alive or how he got separated from Francis.

Major Everly
The man in charge of Millhaven, Major Everly does not believe in the Special Infected's various abilities, nor in their existence, and refuses to believe the Infected are capable of climbing the 20 foot walls surrounding Millhaven. Major Everly is eventually overthrown by Lt. Mora after the Lieutenant sounds the alarm and storms into the Major's office with two other soldiers, presumably from his platoon. While Mora and his soldiers attempted to make their way out of the facility, Everly rallied those soldiers still loyal to him to attempt an evacuation via helicopters. Unfortunately, the rampaging Tank that killed Mora attacked Everly's helicopter as it was departing from the base and threw it at the Survivors, causing it to explode and kill all of it's passengers, Everly presumed to be among them.

Lt. Mora
A paranoid soldier of high ranking who is concerned about the safety of Millhaven under the leadership of Major Everly, as well as believing Carriers and Infected being as bad as each other. Lt. Mora personally took part in the rescue mission of Bill, Francis, Louis, and Zoey in order to witness the Infected for himself, especially the Special Infected. Lt. Mora believes so many Carriers in Millhaven is a bad thing, and overthrows Major Everly due to disagreements on the safety of the military outpost as well as refusing to risk his platoon in a supposedly "unsafe" outpost, or for Carriers who might as well be on the Infected's side. During the events of part 3's comic, Lt.Mora fought alongside his soldiers, ensuring all of them gets to safety before he does so, however an infected manages to take off his gas mask before he could get himself to safety. His soldiers, out of fear that he might now be Infected, decide to leave him for dead. After slaughtering the horde of Infected, he confronts the Survivors, who appear like monsters to his Infected eyes. Francis convinces him that everything is Louis' fault but before he can attack Louis, Lt. Mora is decapitated by a rampaging Tank.

Jeff and Annie
Two soldiers who guard Louis and Francis' cell at Millhaven. Louis explains to them the various Special Infected, which they know nothing of (the only exception being Lt. Mora giving them the name of the Smoker). When the compound is attacked by Infected, Jeff and Annie follow Louis' instructions in avoiding a Witch, which they repay by freeing the two Survivors from the cell, before taking them to the armory to get firearms. They encounter a Boomer, which Jeff shoots at initially, but is thrown off-balance by Louis while Francis dispatches it. Jeff then arms Louis with a pistol, while Francis gets one off the now-dead Boomer. Jeff and Annie allows Louis to take point due to his superior knowledge of the Infected. During part 3 of the comic, both of them along with the doctor, follow the Survivors, thus making them the only few Survivors making it out of Millhaven alive. However, nearing to an end, Jeff and Annie decide to leave for another choke point, stating that their gas masks might eventually malfunction and the disease might spread to them if that happens. At the end of the part 3 comic the base is overrun with the infected and they, along with a few other survivors, attempt to board the train, but fail to do so, partly due to Bill refusing to slow down. It is shown that Annie does not survive the horde assault as shown in one picture of her gas mask being taken off and her trying to fight off the Infected as they swarm in on her. In the same frame the canister of a gas mask can be seen lying next to her on the ground,suggesting a masked corpse there which could be Jeff. Also in the final frame 4 military corpses are on the ground, and it is likely Jeff is among them.

The Doctor
A doctor at Millhaven, who collects saliva from Zoey in an attempt to find a cure. He is pessimistic about his chances, and states that the Army will kill him when they realize he can't stop the Infection. He offers to help Bill and Zoey escape from Millhaven, providing they can get him out as well. He accompanied the Survivors from Part 2 to Part 3, and attempted to tag along with the Survivors to head down to the south. However, he failed to get on the train before Bill started it up. His final moments show him being ensnared by a Smoker while reaching out just inches from the train's door until the Infected swarm him. Zoey, wanting to help him, tells Bill to stop the train. Bill, however, ignores her, and the Doctor is killed.

Rivera
A soldier guarding Zoey and Bill while they are tested at Millhaven. He outraged Bill and Zoey when he threatened her at gunpoint, so Bill distracted him while Zoey hits him with it. His gas mask being dislodged in the struggle, Rivera entered a state of panic, fearing infection from Zoey and begging her not to approach him. His fate is unknown as he is carried off by another soldier who arrives on the scene when the Doctor shouts out "Rivera's down!".
