Bill Overover: A gray-haired, cynical, weathered Vietnam veteran with a perpetual cigarette dangling from his lips; he wears an olive-green military jacket, cargo pants, and worn boots, leading with iron discipline and zero patience for mistakes.

Francis: A rebellious, arrogant, and sarcastic biker who hates everything except rock music and leather jackets; he sports fully tattooed arms, a tight white tank top, a vest with patches, and ripped jeans, making mocking comments even on the verge of death.

Louis: An optimistic, energetic, and slightly naive systems analyst who tries to keep the group's spirits up; he wears a white office shirt with a loose tie, dress pants, and formal shoes that reflect his life before the collapse.

Zoey: A bold, resilient, and resourceful film student who acts as the team's moral compass; she wears a red hoodie, simple jeans, and canvas sneakers, combining youth with surprising lethal survival skills

Coach: A good-natured, protective, and voracious high school football coach; he wears a blue sports polo shirt with white details, sweatpants, and sneakers, combining a big heart with imposing physical strength.

Nick: A cynical, selfish, elegant, and distrustful professional con artist who only seeks to save his own skin; he wears an impeccable white designer suit stained with blood, a light blue shirt without a tie, and a characteristic fedora hat.

Rochelle: A practical, sensible, and determined television producer who tries to stay calm amidst chaos; she wears a light pink t-shirt with a dark vest, skinny jeans, and comfortable sneakers ready for long runs.

Ellis: An enthusiastic, talkative, and somewhat naive Southern mechanic who loves his friend Keith's stories; he wears a backwards baseball cap, a gray tank top, mechanic's overalls tied around his waist, and worn work boots.

1. Dead River
   Context: A system of locks and river dams one week on the verge of collapse. The water is contaminated with debris and bodies washed down from the south. The mechanically disabled gates force passage through a flooded hydroelectric plant.
   Events: Water reservoirs are teeming with Boomers. Rusty walkways at risk of collapse and areas where splashing while running attracts instant hordes.
2. Ghost Highway (Interstate Ruins)
   Context: A mile of asphalt blocked by thousands of burned-out military vehicles and civilian convoys trapped since day one. Tall weeds devouring the pavement and service tunnels.
   Events: A claustrophobic open-air labyrinth with no high shelters. Zero visibility between vehicles. Smokers and Hunters use the rooftops as nests; any shot triggers a chain reaction.
3. Sanatorium San Judas (Quarantine Zone)
   Context: A massive militarized medical complex that served as the first mass quarantine center. The magnetic containment doors remain closed.
   Events: Look for generators and cards in morgues and psychiatric wards. Corridors with flashing emergency lights, high concentration of Witches in rooms and common areas wearing hospital gowns.
4. Bastion of Silence (The Last Outpost)
   Context: An improvised fortified base has been set up in an open-pit mine that collapsed from within days ago. There is no military rescue operation; the objective is to activate an industrial tunnel boring machine.
   Events: Massive defense against the clock. The deafening roar of the machinery draws relentless hordes from the cliffs, forcing players to contend with Tanks in extremely confined spaces.

Changer: An asymmetrical and bulky mutant. He has a gigantic, hypertrophied right arm that drags along the ground, while the rest of his body is relatively small and fragile. He executes an unstoppable frontal charge at high speed, taking out the first survivor in his path. He will slam the victim into the ground repeatedly until they are incapacitated, unless the team manages to interrupt him.

Witch: A pale woman who wears only underwear or rags, with long hair covering her face and razor-sharp claws instead of nails. She is usually found sitting and crying in the dark. She is neutral as long as she is not disturbed, but if she is illuminated with flashlights, approached too closely, or shot, she becomes a deadly threat. She attacks with terrifying speed, capable of decimating a survivor with a single, well-aimed blow on the highest difficulty.

Tank: He is the ultimate boss of the game. He possesses a massive health bar, can hurl large chunks of pavement or vehicles into the air to decimate the team, and his brute strength sends survivors flying with a single blow, easily killing them or knocking them off the map. A colossal mass of pure muscle and unleashed fury, his torso and arms are enormous, with prominent veins, a shattered jaw, and scraps of clothing that barely cover his massive frame.

Meatwall: An amorphous, colossal mass of hypermutated human tissue, fused cartilage, and suffocating limbs that crawls along, blocking narrow passageways and entire streets. The Green Flu in this specimen reacted, turning it into a living biological sinkhole. It absorbed dozens of infected and fallen survivors, fusing their bodies into a titanic, multicellular shell that drips bile and clotted blood. It has no defined human form; it is merely an organic wall of convulsing flesh that breathes with a hoarse, muffled drone. It is slow but lethal. If it eats zombies, it regenerates slightly, but if it is a special zombie, it is damaged.

Jockey: This is a special dwarf infected, primarily weak with only 325 hit points. He has a large hump, wears a white t-shirt and blue shorts, and his lips have been torn off, revealing his teeth. His main function is to climb on top of survivors to incapacitate them or throw them to a great height to kill them.

Smoker: A tall, emaciated individual with blistered, grayish skin and a grotesquely elongated tongue that hangs from its mouth and coils around its torso. It uses its long tongue to grab a survivor from a distance and drag them toward its position, leaving them vulnerable and isolated. Upon death, it leaves behind a dense cloud of toxic smoke that obstructs vision and causes uncontrollable coughing in anyone who inhales it.

Boomber: A grotesquely obese human with a hyper-distended abdomen filled with toxic bile. His skin is swollen, translucent, and covered in festering blisters on the verge of bursting. He is the most fragile in melee combat and falls with just a few shots, but his specialty is spewing a jet of corrosive bile that temporarily blinds survivors and attracts a massive horde of common infected. If he dies too close, he explodes, covering everyone in a nearby radius with the same substance.

Spitter: An extremely thin woman with an unnaturally elongated neck and jaw, and pale, taut skin. Her mouth constantly drips green stomach acid. She spits out a projectile of corrosive acid that creates a toxic pool upon impact. This acid inflicts massive damage on survivors who stand over it, forcing them to constantly move and breaking defensive positions.

Hunter: A young man dressed in a dark hoodie and sweatpants. His body is adapted for extreme agility, with noticeably defined leg muscles and a crouched posture like a feline. His function is to pounce and claw until he dies.

•What it is: It is an artificially created flu/virus that got out of control, affecting the United States. Its symptoms include contractions, vomiting, extreme rage, loss of appetite, and advanced resistance.

•How it affects you and how it is contracted: The green flu, like other viruses in other video games, is contracted through scratches, bites, and mainly bodily fluids. It primarily affects the body; you won't lose control of it, you'll just be so aggressive that you'll see normal people as prey. The infection affects common systems, since those affected can still smell, hear, and walk.

•The immune: Just like many viruses in real life, there are immune people. These people have special blood that prevents them from being infected by the green flu. Although it's very rare, and you are one of them.
