Left 4 Dead

These are reinforced rooms or buildings, identifiable by their red armored doors, designed to offer safe rest and resources to survivors between waves of infection. They were built by the CEDA (Civil Defense and Emergency Agency) or other survivors, serving as checkpoints where special infected cannot enter.

• Security: These are impregnable places for the infected once the door is closed, allowing the characters to recover.

• Resources: Inside, survivors find first aid kits, weapons, and ammunition, often supplied by the CEDA.

• Connectivity: They function as the endpoint of each chapter, allowing the transition to the next level.

• Narrative: These are fundamental to the plot, as the characters use them to progress through the infected cities. At the end of each subchapter, the survivors will reach a shelter.

• First aid kits: Easy to make and find (if you know how to look well), these kits allow you to heal or at least recover from old wounds.
• Pain pills: These pills allow you to feel much better, feel happier and without feeling pain, and also allow you to recover momentarily from injuries.
• Adrenaline injection: When injected, an adrenaline rush reaches the survivor who injected it, allowing them to move much faster and not feel pain for a few seconds.

Pistols:

• M1911: An American classic, offering a medium-high performance thanks to its large .45 ACP caliber. It has 10 rounds per magazine.
• Glock: A much more modern weapon with the ability to mount a flashlight underneath. It's small, portable, has decent damage, and a 15-round magazine capacity.
• P220: It is identical to the Glock, with the difference that it has 12 bullets per magazine, but its damage is slightly greater thanks to the possibility of using armor-piercing ammunition.
• Desert Eagle (Magnum): The pistol with the highest damage output. Using the .50 Action Express caliber, the Desert Eagle is a pistol with significant recoil and a 7-round magazine capacity, but capable of decapitating many infected.

Melee weapons:

• Fireman's axe
• Baseball bat
• Metal lever
• Cricket Stick
• Frying pan
• Chainsaw
• Golf Cloth
• Combat knife
• Guitar
• Katana
• Machete
• Police baton
• Shovel
• Fork

Throwing weapons:

• Molotov: Easy to make, very useful against hordes and against the Tank to set them on fire.
• Homemade bomb: As its name suggests, it is a homemade plastic explosive, shaped like a cylinder, with a timer and detonator. When its fuse is activated, it begins to emit a series of high-pitched, loud beeps that attract common infected exclusively to the homemade bomb, which then explodes.
• Vomit: The bile of the special infected Boomer, also known as "Vomitona," is a green liquid containing a type of pheromone that, when released, attracts common infected. Bottles containing this liquid, originally intended for research, can be found at the CEDA. When these bottles are thrown at infected individuals, releasing the vomit, they will begin fighting amongst themselves.

Shotguns:

• Pump-action shotgun: An 8-cartridge capacity shotgun with a wooden stock and slide.
• Chrome shotgun: It is a pump-action shotgun but much more modern and with a capacity of 10 cartridges.
• Automatic Shotgun: This shotgun has a 7-cartridge capacity, but it is also capable of firing continuously and without the need for a slide for each cartridge.
• Combat Shotgun (also called Spas 12): It is an automatic shotgun with a capacity of 10 cartridges and with less dispersion of its pellets, performing very powerful damage.

Submachine guns:

• Uzi: This compact submachine gun with 30 bullets per magazine is very useful for confined spaces.
• Mac 10: This weapon with a silencer and a capacity of 40 bullets per magazine allows you to stealthily eliminate many common infected.
• MP5: This submachine gun is the most advanced, although it does not have a silencer, its rate of fire, its capacity of 45 bullets per magazine, and its high damage make it the ideal choice of compact weapons to face the hordes.

Assault rifles:

• M16: Bill's favorite. An American classic with 30 bullets per magazine and standard damage, plus it's moderately lightweight, making it a balanced option for facing the undead.
• Combat Rifle (Scar): A powerful and accurate burst rifle, useful for medium and long range combat, offering superior damage but with controlled recoil thanks to the burst firing.
• AK-47: The rifle with the highest damage output, it's very reliable in all situations, using high-caliber ammunition and with a standard capacity of 30 rounds per magazine. Although it has high recoil, this is compensated for by its enormous headshot capability.
• SG 552: Assault rifle with a variable zoom optic. Its damage is somewhat reduced, but its low weight and maneuverability make it an acceptable option at short, medium, and long ranges.

As a secondary force, they participate in the attempt to contain the Infection, deploying makeshift military outposts, rescue zones, and military equipment so that survivors can defend themselves against the Infected. Unfortunately for the Army, many of its members have succumbed to the Infection and appear (in their camouflage uniforms) among the vast hordes of common Infected, or have died in combat.

During the three weeks of the Infection, the Army worked alongside CEDA in an attempt to combat and halt the spread of the Green Flu epidemic. Since CEDA failed to contain the virus, the Army assumed responsibility as the Infection spread throughout the country. Initially, the Army's strategy was to evacuate and rescue as many people as possible, but once this became less feasible, the political decision to declare martial law was clearly made. This allowed the Army to implement more direct and draconian measures to contain the threat and attack the invaded areas of the country. One such measure involved forcibly separating Carriers (people infected with the Green Flu but asymptomatic) from Uninfected Survivors (people who had not been in contact with the Infected) and burying the bodies of the Infected in mass graves.

CEDA is a United States government agency tasked with protecting the nation's people from the consequences of disasters and assisting in recovery efforts. Its brief involvement during the Green Flu Crisis is notable, as it studied the virus and attempted to keep civilians safe from infection. The agency maintains operational equipment, trained personnel, and a strict firearms policy for most of its partner organizations, with some exceptions such as the military and its various branches. Little is known about its actions prior to the Green Flu outbreak, nor is there an official report on its role in that disaster. What is clear, however, is that the CEDA is currently decimated and has been relieved of its role as the primary agent in containing the virus, as its efforts to address the crisis ended in complete failure due to its ineptitude.

When the infectious outbreak began, CEDA promised evacuations; however, it locked several inhabitants in different quarantine zones, which, not being able to distinguish the infected from those who were not, allowed infected people to enter the bases, thus getting out of control, due to the agency's ineptitude.

The special infected are a little smarter than the rest, able to improvise plans to combine their skills and kill any survivors they find.

• Boomer: When it vomits, the Boomer attracts a small horde, which can be very annoying and dangerous when the other Special Infected are involved. This Special Infected is capable of combining with any of the others.

• Jockey and Smoker: These are the perfect specimens when it comes to separating the team. The Jockey uses his weight to guide the survivor he has grabbed, scratching their face to prevent them from seeing and moving them away from the rest. The Smoker operates from high places or dark corners, shooting out his long tongue and dragging the survivor or hanging them, where he strangles them and gives the other infected, both common and special, the opportunity to kill them.

• Hunter: The Hunter is the most stealthy of all, leaping from great heights without taking damage, climbing at high speed, attacking from the shadows, and knocking survivors to the ground. When someone on the team becomes separated, the Hunter takes action.

• Charger: The Charger usually makes surprise attacks, and is commonly the one who initiates open combat. It waits in corners, behind doors, and anywhere it can hide its large body to run and charge with its enormous arm.

• Witch: On her own, the Witch does not attack anyone unless she is bothered, but the rest of the special infected can take advantage of this opportunity, cornering and forcing the survivors to approach her.

• Spitter: His acid attack allows him to momentarily block the path of survivors, creating attack opportunities for the rest of the infected.

• Tank: Although he is sometimes an uncontrollable beast, the Tank can also be an infected with a certain level of intelligence, sometimes allowing the rest of the special infected to wear down the survivors before taking action.

• Smoker: Coughs a lot and screams loudly when he sees a survivor or when he is about to attack someone.

• Hunter: Despite being almost always stealthy, when the Hunter is about to attack, it begins to growl like a panther.

• Jockey: It's easy to tell there's a Jockey nearby, as they usually laugh or shout like crazy.

• Charger: Emits sounds and grunts similar to those of a bull, and when it is about to run to charge, it screams as if it were a bull.

• Spitter: The shiny drops of acid it leaves on the ground give it away.

• Boomer: The loudest infected of all. He burps, always makes sounds as if he's nauseous, and is always complaining.

• Witch: You can always hear her crying loudly.

• Tank: The ground trembles beneath his feet, he grunts like a gorilla, and he also kills other common infected.

• Tank: This mutation most likely occurred in people who consumed anabolic steroids.

Tanks are large infected (measuring around 3 meters tall and 2 meters wide). Their arms, shoulders, and torso are disproportionately developed, while their waist, hips, and legs are less pronounced in comparison. They have a reddish skin tone, badly cracked and damaged by infection. Their faces retain vaguely human features, but deformed by a powerful jaw and small eyes. And what stands out most is their gait; they walk hunched over, supporting much of their weight on their knuckles, which gives them a simian, hominid, and threatening silhouette.

Tanks are found outdoors, in wide-open spaces, mainly the streets. But luckily, few of those infected with the green flu mutate into these creatures.

There's no need to talk much about his abilities, as they are quite obvious given his appearance. It possesses great strength, capable of destroying walls, scaling buildings, throwing cars, killing someone with a single blow, etc. The Tank also has high resistance to gunfire, continuing to attack even when severely wounded.

But the Tank also has weaknesses. The most important are:

• His slowness: for being a huge infected, he is quite fast, but he is slightly slower than an average person.
• Fire: fire wears it down quickly, so Molotov cocktails are the best option against it.
• The chaos it causes: Sometimes it can accidentally kill other infected people who cross its path while chasing its prey.

• Witch: The Witch mutation appeared primarily in people with mental illnesses, mainly women. They have bright red eyes and very pale skin. But what stands out most about them are how their fingers mutated into long, sharp claws.

Witches are always in a state of distress, so they can always be seen crying, moaning, and somewhat hunched over. But the most important thing about Witches is that they are passive-aggressive infected. They are docile as long as their crying isn't interrupted; shooting them, shining flashlights on them, or getting too close will cause them to enter a very aggressive state, in which the Witch will run towards whoever bothered her and kill them quickly with her sharp claws and superhuman strength. However, if a Witch's crying has been disturbed or interrupted but she hasn't attacked yet, if you don't make any sudden movements, she will ignore whoever interrupted her and resume crying (this does not apply if she is attacked).

There are two types of Witch: The wandering Witch and the tired Witch.

• The Wandering Witch is a Witch who walks slowly and stumbles with her hands covering her face. They are commonly seen during the day.

• The tired Witch, who appears almost always at night, is always sitting on the ground crying in some dark place, whether it's a house, an alley, etc.

Point-blank shots are much more useful for killing a Witch.

• Boomer: Clearly, the Boomer is a mutation that occurred in people with morbid obesity. This infected person is notable for (in addition to his obvious obesity) having large swollen, pus-filled lumps in different areas of his body, mainly on his chin and abdomen, and his skin turned a grayish color but with some green tones, mainly on his abdomen.

The Boomer's ability was named "Pucricide" by the CEDA. It consists of vomiting a wide jet of green, watery vomit at high speed and from a distance of about 10 meters at its victim. The Boomer's vomit, called "vomitone," contains pheromones that attract common infected and also momentarily cloud the vision of its prey.

The Boomer on its own is a weak, slow, very noisy, and not very resilient infected, but its vomit is capable of attracting small hordes of common infected.

Furthermore, when the boomer dies, it explodes with force, expelling flesh, viscera, and vomit everywhere, so you must keep your distance from this type of special infected if you want to kill them without getting hurt or covered in their infectious fluids.

• Jockey: It is unknown what type of people the Jockey mutation affects, but their appearance is known. Jockeys appear quite hunched over with pronounced scoliosis, very short in stature (around 150 or 160 centimeters tall), with a clear lack of lips, revealing their large and deformed teeth. This infected one is elusive and agile, walking at high speed. Sometimes it laughs, probably due to a high amount of adrenaline in its body.

This Infected's "ability" has been termed "enslavement" by the CEDA. The Jockey leaps onto its victim's back, entangling its legs around the prey's torso and viciously scratching their face and eyes. In addition to this attack, the Jockey uses its body weight to guide its prey in any direction it desires, preventing the victim from moving freely until the Jockey is eliminated. The problem is that eliminating the Jockey with gunfire while it's mounted on its victim is very difficult, as the chances of accidentally shooting the victim are very high; therefore, melee weapons are recommended.

The Jockey's weaknesses are his low resistance to damage, dying from just a few shots or blows. He is also poorly stealthy, often unable to suppress his laughter, which betrays his position.

• Smoker: The Smoker is a mutation that appears in people who smoke and likely have lung cancer. Smokers are typically tall, between 180 and 185 centimeters in height. These creatures possess large, round, amorphous, cancerous growths around their cheek (usually the left), on their chin, on their neck, and on their arm (usually the left). But the most prominent feature of their appearance is their mouth, from which protrudes their long, rough, cylindrical tongue, which can extend to any distance the Smoker desires (up to a maximum of approximately 50 meters).

The Smoker's attack consists of three phases, the first phase is the "grasp", in this he will "shoot" his tongue towards his victim, and then his tongue will entangle itself in the hips, chest and neck of the prey. The second phase is the "drag" phase. In this phase, the Smoker will drag its victim toward it with its tongue. Two things can happen here, depending on where this phase occurs. If the Smoker was at a height (like on a rooftop) and its victim on a sidewalk, it will leave the victim hanging in the air, strangling them. But if the Smoker and its prey are in a straight line, it will drag the victim toward it, where the third phase of its attack will take place. The third phase of the Smoker's attack is "asphyxiation and contusion," its tongue will squeeze the body of its victim, taking away all the air and breaking it, and at the same time it will hit its prey on the head with all its strength, killing it.

The Smoker has two major weaknesses: The first is its tongue, which can be easily cut with a sharp object (knife, metal bar, axe, etc.) or shot out. Its second weakness is the faint trail of dark green smoke it leaves behind, which betrays its position.

An interesting fact is that, upon dying, the Smoker will release all that same smoke from his body, momentarily clouding vision and causing dizziness.

• Spitter: Spitter is a mutation that commonly occurs in women with serious gastric problems. This Infected has a rather disgusting appearance. It looks just like an ordinary woman, but its neck is elongated and covered in burn marks, its eyes are yellowish, and its mouth is also heavily burned, with exposed gums since it has no lips. Its stomach is slightly swollen, and its limbs are somewhat elongated.

The Spitter's ability is to spit extremely hot bile at high speed. When this bile hits the ground or prey, it spreads and forms a large pool of a strong acid that burns everything it touches.

The Spitter is not a very strong or very resistant infected, so it prefers to attack at key moments and always alongside other special infected.

• Hunter: The Hunter mutation must have occurred in people who practiced high-risk sports or sports that demanded high physical capacity. The Hunter has nothing particularly striking about its appearance to differentiate it from the common infected, except for three things. The first is its face; it has gouged out its own eyes and possesses a highly developed auditory system. The second is its hands, which have dark, dirty, razor-sharp, and resilient nails. These allow it to scale walls at incredible speed due to its astonishing agility, and also enable it to kill with ease. And the third most notable feature of this infected is that you will never see it among the common infected, as it is very stealthy and tends to lurk in high places like rooftops, waiting for an opportunity.

This type of special infected possesses some very surprising and lethal abilities, the first being its stealth. The Hunter makes no noise while walking upright, remaining completely silent and moving with agility, but when it crouches and prepares to attack, it growls loudly and then screams. His other ability is his practical immunity to falls; no matter how high a fall is, this Infected can withstand it. And its main ability is jumping. The Hunter is capable of making enormous, long leaps of up to 30 meters, attacking its victim by surprise.

A very important characteristic of this Infected is its habit of "exenteration." Upon leaping upon its prey and knocking it to the ground, it climbs on top of it and begins to disembowel it with its sharp claws.

• Charger: This mutation likely occurred in individuals with gigantism. This infected person has the appearance of someone tall and robust. Their head is bald, their back is very broad, and their skin is covered in a thick, hard, and rough crust of a dark green color with patches of dried or clotted blood. But what stands out most about this Special Infected are their arms; the left arm is very thin, atrophied, and flabby, but their right arm, the one they use as a weapon, is amorphously large and deformed, covered in blood and the same thick crust that covers their body.

The Charger's attack consists of two phases. In the first, it runs toward its prey at an abnormally high speed in a straight line, ultimately impacting and dragging it at full speed against a structure. This attack causes severe bruising and is capable of breaking bones, as it is a charge with explosive force. The second phase of its attack involves grabbing its prey by the torso with its large arm and then slamming it repeatedly against the ground until it is killed.

The Charger itself has no weaknesses, but its poor maneuverability while running can be exploited. When the Charger is in the initial phase of running towards its target, it's easy to dodge if you've already spotted it, as it has a very hard time turning while running.

• Special Infected: These infected are not very numerous, usually appearing in 1 to 4 waves. However, the individual danger they pose is much greater than that of a common infected, as they represent a small segment of the infected population that mutated as a result of the virus and received special abilities. These infected possess a certain level of "intelligence," as they are capable of organizing themselves, and when they attack in conjunction with a horde or other mutations, good cooperation from the four survivors will be necessary to defeat them.

(The survivors are unaware of the special infected until they see them for the first time. They will have to improvise to deal with them.)

The infected, also known as walkers or, by the military, as the Living Dead (using the radio alphabet), are those infected by the Green Flu virus and are the primary enemy of the survivors. They are sometimes called zombies, although this term is inaccurate, as they are still alive, not reanimated corpses.

• Common Infected: Also generally referred to as "the horde," they represent the vast majority of the infected population and are those who did not mutate due to the virus. Their mutations include the loss of their reasoning abilities and superhuman agility, making them rabid and dangerous beings. While a few can be easily dealt with using a pistol, their power lies in their presence throughout the cities of the East Coast. They will not hesitate to attack anyone who is not infected or carrying the virus. Common infected are attracted to sound, so triggering an alarm, explosions, and any loud noise (excluding gunfire) will draw a horde. This attraction to noise is a double-edged sword, as the whistling sound of homemade bombs makes them effective decoys before the subsequent explosion. They are also (likely due to pheromones) attracted to Boomer vomit and his bile bottles.

Something that characterizes these creatures, besides the fact that they run quite fast and are a huge danger when they come in hordes, is that they are very weak, being able to die from a few shots or a few blows.

Its origin is unknown; it is speculated that it was a product of the CEDA or a mutation of a current virus (or the appearance of a new one), and although it has certain similarities to rabies, it is not rabies.

SPREAD: It is not clear how the infection spreads. The following are only possible causes of transmission:

• Airborne virus: Some believe that it spreads through the air and that it is a virus, being able to spread in the same way as a common flu (sneezing, saliva, etc.).

• Special infected: Other theories propose that the transmission of the infection is by special infected, such as the Boomer, Spitter and Smoker, the virus is transmitted by vomit, saliva and smoke respectively, these being the cause of its spread.

• Virus transmitted by contact: When there is contact with an infected person, such as being hit by one, it is likely to be transmitted, which is why the infected hit the survivors trying to "infect" them.

• Carriers: Despite being infected, the protagonists possess a biological immunity that prevents them from losing their minds like the common infected. These are called "Carriers." However, they are still attacked by the infected and are a source of virus transmission, which implies two things:

The virus is airborne and behaves like the common flu (spread through sneezing, saliva, etc.). Alternatively, it can be transmitted through physical contact with an infected person.

As mentioned above, Carriers are people exposed to the infection who have a natural resistance to it and therefore do not mutate and retain their sanity. However, Carriers are not completely immune, as they carry the virus and spread it like a common infected person. This makes them even more dangerous than common infected people because they could (unknowingly) enter shelters and infect those who are not immune.

Louis is an African American man in his 20s or 30s, whose design reflects his past as an office systems analyst. He wears a light blue dress shirt with an undone tie, dark dress pants, and shoes, giving him a professional yet disheveled and chaotic post-apocalyptic look.

Likes and Hobbies (What he loves):

• Pain pills: They are their main obsession and relief for anxiety and fear.

• Weapons: He is passionate about shooting, especially machine guns and pistols, which he used to use at shooting ranges before the outbreak.

• Optimism/Humor: Try to maintain a positive attitude and relieve tension with jokes, even in extreme situations.

• Camaraderie: He genuinely cares about the safety of his fellow survivors.

Dislikes and Fears (What he hates):

• Stress and anxiety: The zombie apocalypse causes him great stress, which he combats with pills.

• The Infected: Although he fights against them, the blood and horror of the outbreak initially had a great impact on him.

• High-stress situations: Despite his positive attitude, he often appears nervous, fearful, and cries out in danger.

• The possibility of being devoured: He is horrified by the idea of ​​being caught.

Key traits of Louis' personality:

• Extreme (and sometimes naive) optimism: He maintains a positive outlook, which often clashes with Francis's cynicism.

• Pill addiction: Sometimes he seems to have a need for pain pills, theorizing that he uses them to control stress and anxiety after being a stressed office worker.

• Intellectual but timid: At the beginning of the infection, he appeared fearful and nervous, but he evolves into a functional member and strategist of the group, capable of using weapons efficiently.

• Concern for the group: He genuinely cares about the safety and well-being of his fellow survivors.

Louis: Before the Infection, Louis worked as a systems analyst at Franklin Brothers in Philadelphia, Pennsylvania. During his lunch breaks, he would often visit the shooting range, something his coworkers teased him about. It can also be assumed that Louis was a video game enthusiast, as he was known to play several Valve games, such as Half-Life, Counter-Strike, and Team Fortress, and to own an Xbox video game console. Two days after the infection began, he encountered his first Infected in his office, in the men's restroom, after trying to convince a coworker that the press was exaggerating and everything was fine. After killing the Infected, he left the restroom only to find his office in ruins, his coworkers dead, and the outside world falling apart.

At some point Louis met Zoey, Bill and Francis and they continued their journey together.

Francis is a 6-foot-tall biker with a rugged and rebellious appearance. He stands out for his sleeveless black leather vest over a white t-shirt, distressed jeans, tattoos on both arms, and a few days' growth of beard. His look reflects a tough, sarcastic, and daring personality, focused on action.

Main Dislikes ("I hate..."):

• Places and Structures: Hospitals, hotels, sewers, tunnels, bridges, barns, airports and the cold.

• Situations: Elevators, flying (airplanes/helicopters), and suicide missions.

• Authority Figures: Police officers, lawyers, doctors. Others: Zombies, vomit, birds, Bill's plan, and Louis's optimism.

Tastes and Preferences:

• His Vest: It is his most prized possession; he gets furious if it gets dirty.

• Action: Motorcycling, tattoos, joking, and fighting.

• Food: Lasagna.

• Specific things: The race car of the famous driver Jimmy Gibbs Jr., and deep down, he admires the loyalty and willpower of his teammates.

Main features of their behavior

• Widespread hatred: He is famous for openly expressing his contempt for almost everything around him. He hates hospitals, airplanes, submarines, the police, and the law.

• Natural rebellion: As a former biker of the "Legion of Hell" gang, he enjoys the total absence of rules and the established social order.

• Hidden loyalty: Although he appears rude, unfriendly, and often insults or verbally belittles his teammates, deep down he is the team member who cares most about them in situations of real danger.

• Material obsession: He has an unconditional love for his black leather vest. He constantly threatens to shoot anyone who gets it dirty with zombie blood.

• Cynical humor: Uses sarcasm and heavy-handed jokes to lighten the tension of the group, functioning as the comic relief of the team.

Francis: At one point, Francis was employed by the Hersch shipping company but was supposedly fired after assaulting a man. Francis attempted to steal a flat-screen television two days after his first infection. When caught, he claimed to be a police officer, but was arrested. Later, while at a bar telling his friends why he was going to jail, one of them revealed that Pennsylvania prisons don't allow conjugal visits. Francis's presumed girlfriend, Sandra, then said, "Better not waste any more time," grabbed Francis's arm, and led him away. Francis and Sandra began kissing in the back room when she became ill and vomited on his vest. He almost left, but she convinced him to stay and then bit him on the neck. She was about to attack him when Francis's friend, Duke, shot her. Realizing that this is no ordinary flu and that most people can't be considered more human, Francis understands the potential for anarchy that the Infection has brought, and goes with Duke and Danny to the rooftop by a jukebox where he grabs a shotgun and starts killing all the Infected one by one with Duke, Danny and some other companions from the Bar.

What happened to his friends afterward is unknown, but it's most likely that he left them behind, or they weren't immune or carriers and succumbed to the flu at some point. At some point, Francis met up with Bill, Zoey, and Louis, and they continued their journey together.

Zoey is a young college student with dark brown hair, brown eyes, and an athletic build, known for her iconic red blazer. Her style combines comfortable clothing with a student touch, wearing an Aldrich University t-shirt under her blazer, jeans, and practical footwear—ideal for surviving the apocalypse.

Tastes and passions:

• Horror and science fiction films: She is passionate about horror movies, subgenres like slasher films, and stories about aliens. She watched this kind of content constantly from a young age. Her somewhat calmer attitude toward the apocalypse is because she "had already seen it in movies," although that doesn't change her nervousness.

• Firearms and target shooting: Her father, a police officer, frequently took her to shooting ranges so she could learn self-defense. This gave her excellent aim and made her comfortable using pistols and assault rifles in the game.

• Pop culture and references: He often quotes lines from iconic movies during campaigns, breaking the tension in the group.

• The group of survivors: She developed a strong emotional and protective bond with Bill, Francis, and Louis. She saw Bill as a father figure and deeply respected his military leadership.

Dislikes and traumas:

• Abandoning other survivors: He detests the cold military logic of sacrificing lives for the greater good.

• University and expectations: Before the outbreak, she was a student at the state university, but she was a disinterested and lazy student who preferred to skip classes to watch movies. She also disliked the family pressure regarding her professional future.

• The special infected (particularly the Smoker and the Tank): Like his companions, he expresses explicit disgust and revulsion towards the mutated infected who constantly put his life at risk.

Main traits of his character

• Kind heart and altruism: Constantly prioritizes the well-being of others over mere survival.

• Tragic resilience: Maintains a positive and firm attitude despite having witnessed the death of his parents.

• Maturity and rapid adaptation: Although she is the youngest in the group, she demonstrates a great ability to assimilate extreme situations.

• Film buff humor: Uses references to classic horror movies to deal with the stress of the infection.

• Unwavering loyalty: Develops a deep emotional and protective bond towards teammates.

Zoey: Zoey was once an Aldrich student in Philadelphia on a scholarship to become a film director, but instead of attending classes, she spent her time watching horror movies and justified this to her angry mother by claiming she was doing "research." She got her love for this film genre from her father, who introduced her to movies featuring zombies, serial killers, and aliens at a young age. Her father, Wade, wanted her to become a police officer like him and often took her to the shooting range to give her some practice. These actions caused tension between her divorced parents one night, and they began a heated argument about their daughter's future. The argument was interrupted, however, when an Infected suddenly entered their living room and attacked Zoey's mother, Carolyn. Her father was able to kill the Infected, but not before Zoey's mother was savagely attacked. He scooped Carolyn up in his arms and told Zoey to call an ambulance. Zoey returned just in time to witness her father being mutilated by her mother, who then noticed her daughter and quickly lunged to attack her. Fortunately, before she could reach Zoey, Wade shot her in the back of the head. His dying wish was for Zoey to kill him before he became an Infected. Zoey then took her father's gun and, after saying with a broken heart, "I love you, Dad," she pulled the trigger.

At some point Zoey met Francis, Bill and Louis, and they continued their journey together.

William "Bill" Overbeck, 55, is a Vietnam War veteran. His appearance reflects his military past: olive drab jacket, 5th Special Forces Group beret, black tactical vest, dog tags, and a perpetual cigarette dangling from his lips. He is distinguished by his white hair and gray beard, leading the group with a hardened and experienced air.

Main Features:

• Natural Leader and Strategist: Bill uses his military training to make quick decisions and manage life-or-death situations, showing great ingenuity.

• Pragmatic and Tough: He is a man of action, direct and hardened by war, whose physical resistance is remarkable despite his age.

• Unwavering Loyalty: Despite his sometimes gruff attitude, he protects his group above all else, even himself.

• Mentor: Acts as a guide for younger survivors (like Zoey), teaching them how to fight and survive.

• Paranoid/Distrustful: His experience makes him distrustful of authority figures or promises of safe rescue.

Tastes and Preferences:

• Smoking: He smokes constantly, even during critical situations or when he is injured, being one of his most notable characteristics.

• Leadership and Combat: As a Vietnam veteran, he is comfortable in high-pressure situations, taking on the role of group leader and protecting others.

• Firearms: His preferred weapon is the M16 rifle, with which he demonstrates great skill.

• The action: Unlike a quiet life, Bill seems to find purpose in fighting the infected, which reminds him of his military days.

Dislikes and Aversions:

• Weakness/indecisiveness: He has little patience for those who cannot stand firm in dangerous situations.

• Distrust of authority: Deeply distrusts military or rescue figures who promise safety, preferring to depend on the group.

• Inactivity: Following his knee injury before the outbreak, Bill hated not being able to lead an active life, which led him to feel "useless" before the infection began.

Personal Details: Father Figure: Although rough, he shows appreciation for the group, becoming a father figure to Zoey.

William "Bill" Overbeck: Bill served two tours of duty in the Vietnam War. As a member of the 1st U.S. Special Forces Group, he served in the war that ended in 1975. Sometime during the war, he suffered a knee injury from shrapnel that became lodged in his knee, causing permanent damage. Two days after the initial infection, Bill was in a veterans' hospital awaiting knee surgery. When a member of the medical staff tried to bring up Bill's missing family and his smoking habit, Bill told him to go bother someone else. While undergoing anesthesia and slowly falling asleep for surgery, one of the nurses becomes Infected and kills the operating room staff. Bill somehow manages to stay conscious using sheer willpower while simultaneously fighting to stop the Infected nurse. He finds a handsaw and a knife to defend himself and fights his way out of the hospital, then fights his way back home, where he dons his old military gear that had been stored away. He equips himself with his old assault rifle and heads out to fight the Infected on his own.

At some point Bill met Zoey, Francis and Louis, and they continued their journey together.
