Chapter I: Poland Green Virus Outbreak (2016)
The renowned biochemist and geneticist Dr. Bronisław Ujazdowski becomes obsessed with discovering the nature of life and death. While supported by Phoneix Ark Research and its own team of scientists, Bronisław Ujazdowski's behavior becomes more erratic and his experiments take a gruesome turn. The Ujazdowski Mansion in Poland, which serves as his home and laboratory, experiences an outbreak.

On October 15th, 2016, NSA Agent Paul Armstrong receives a distress call from his fiancée Scarlett Winstead from the Ujazdowski Mansion. Armstrong and his partner Regan fly to Poland and arrive at the estate, finding it overrun with undead creatures, which Ujazdowski unleashed. A mortally wounded man gives them a journal containing information about Ujazdowski's creations and their weaknesses. Armstrong and Regan reach Scarlett, only to witness her being carried away by a gargoyle-like creature called the Hedgeman. They later find Scarlett, before she is attacked by the Chariot, a heavily armored mutant armed with a bardiche. After killing the mutant, Armstrong and Regan attend to Scarlett, who tells them they must stop Ujazdowski or else "something terrible will happen," before passing out. A furious Armstrong goes after the Hedgeman to the rooftops surrounding the courtyard. After a lengthy battle, Armstrong and Regan shoot it down. The two eventually confront Ujazdowski who is protected by an armored, spider-like creature called The Hermit. After killing it, Armstrong and Regan continue to proceed.

Arriving at the mansion's laboratory, Ujazdowski unleashes his masterpiece, The Magician, a humanoid creature with pyrokinetic abilities. However, the Magician refuses to serve any master and mortally wounds its creator. Ujazdowski expresses his confusion regarding his creation's loyalty before succumbing to his injuries. Armstrong and Regan battle the Magician until it explodes, and then they leave the mansion.

Chapter II: New Orleans Christmas Outbreak (2019)
NSA Agent Regan's further investigation on the 2016 Ujazdowski Mansion incident leads to his mysterious disappearance upon his discovery of the remnants of Dr. Ujazdowski's operations in New Orleans where a zombie outbreak takes place.

From December 25th, 2019 to January 1st, 2020, American NSA agents Jin Lee and Hal Bailey are dispatched, along with Paul Armstrong and Bradford Sigmund, to investigate and evacuate the populace of New Orleans. They suddenly encounter the impish Zeal, who had recently dealt with Reagan. Upon finding a wounded Regan alive in a local library, Lee and Bailey converse with him. Regan gives them a field journal showing the bosses and their weak points. The pair are then met with a massive undead horde, similar to the kind from the Ujazdowski Mansion incident. They continue on, trying to save the town's civilians from the zombies.

During the chaos, Lee and Bailey face Judgment; consisting of Zeal and his giant, headless, axe-wielding armoured puppet Kuarl. After killing it, they meet up with Armstrong and Sigmund, who split up and try to meet at Six Flags New Orleans (or Jackson Square, depending on the player's actions). Upon getting there the group faces off with The Hierophant, an aquatic fishlike humanoid which heads an assault on New Orleans's waterways. Upon defeating it, Lee, Bailey, Armstrong and Sigmund get on a boat and continue through the rivers.

It is revealed that the zombies were created by Lars Sanderson, the man who financed Dr. Ujazdowski's creations during the Ujazdowski Mansion incident. It is also revealed that Sanderson created the new zombies and released them into the city. Sanderson leaves a message on Armstrong's phone, inviting them to meet him at the Solomon Victory Theater, which Sigmund fears to be a trap. Lee and Bailey split up again, and face off with a group of five fiery serpents known as The Tower. After killing the mother serpent, they receive a phone call for help from Armstrong, before getting cut off. The two quickly race to the Solomon Victory Theater only to discover Armstrong and a wounded Sigmund, injured by Strength, a giant, chainsaw-wielding zombie which wounds Sigmund and chases Lee and Bailey throughout the theater. After they kill it, Lee and Bailey push on, while Armstrong tends to Sigmund's wounds. They drive over to Sanderson's tower, fighting a revived Judgment, the Hierophant, and Tower.

Upon reaching the headquarters, they are confronted by Ujazdowski's masterpiece, The Magician, who was also revived by Sanderson to oversee the birth of The Emperor, a shapeshifting crystalline entity with mastery over magnetism designed to protect nature from humanity. After defeating the Magician, they head to the top of the tower to confront the Emperor. In its prototype stage, the Emperor is not as strong as Sanderson had hoped, and falls to the NSA agents. In order to evade being arrested, Sanderson commits suicide by throwing himself off the roof of his building.

Chapter III: Asia Lab Outbreak (2023)
In 2023, three years after the Lars Sanderson Case, veteran American NSA agent Hal Bailey, and a new rookie agent, Ethan Simpson, are gathering intelligence at the fifth basement floor of the Asian headquarters of the NSA in Vietnam (Seoul in the Italian, French, German, European Spanish, Polish, Swedish or Russian dub). Hal Bailey has a sharp memory of the Lars Sanderson Case Case, and believes that the ordeal hasn't yet ended. A sudden earthquake rocks the room while they talk, collapsing the basement walls and leaving the agents trapped.

Several days later, as the two await a rescue team, Hal Bailey's PDA goes off, and a group of undead are seen on the security cameras. Realizing that they are in danger, Hal Bailey has Ethan Simpson gather all the weaponry they can find to defend themselves. Soon after, the two travel through the sewers to an information room where they uncover a plot to fire nuclear missiles worldwide within 24 hours' time, facing the four-armed giant zombie Justice and a pair of mutant tarantulas known as The Lovers along the way. Taking the subway into zombie-infested streets from an underground shopping district, the agents narrowly avoid attacks by The Empress, a double-ended chainsaw-wielding assassin, and the massive, obese, and nearly impervious Temperance.

Hal Bailey & Ethan Simpson then learn that the late one-time CEO of the now-defunct Phoneix Ark Research, Lars Sanderson, is responsible for the resurgence of undead. All of his messages and current plans were set in motion even before his death. Upon reaching the surface, they find the city completely obliterated. Sanderson sends them a PDA message indicating that the launch will occur in one hour. The agents head for an abandoned Phoneix Ark Research office and upon arrival, a levitating humanoid named The Star, confronts them in the foyer. After the Star is defeated, the duo arrive in time to halt the missile launch, though it is revealed that Lars Sanderson's true intention is to revert humankind to its original state in order to prevent them from harming the planet further. As such, his final legacy, The World, an insectoid humanoid with powers over ice, is released in the opening of "Pandora's Box" to fulfill its role as the successor to his original Emperor project in 2019, having developed underground since his death. As the NSA agents fight it, the World continuously evolves to become larger and more powerful. Following the World's second defeat, Hal Bailey sets his PDA to self-destruct and, telling Ethan Simpson not to give up hope, sacrifices himself to destroy the World in the ensuing explosion. A shaken and distraught Ethan Simpson walks out of Lars Sanderson's office.

Chapter IV: Narlow Manor Outbreak (2026)
In 2026, three years after the events of Chapter 3, Ethan Simpson joins forces with Jin Lee, the partner of her late partner and mentor, Hal, on an undercover mission in a dinner event within Narlow Manor. The manager unleashes his army of mutant creatures upon the dinner guests. Realizing the threat to the world, Simpson and Lee then begin their quest to stop the manager and the outbreak he started.

As they progress through the mansion, they find clues related to the personnel of Phoneix Ark Research; Dr. Ujazdowski, Lars Sanderson, and a mysterious man which Ethan identifies as Manheim, a descendant of the corporation's founding members, as well as the manager of Narlow Manor. Also during their exploration of the mansion, they fight gigantic mutants, such as resurrected creatures from the 2016 Poland Incident, Chariot and Hangedman, as well as a new squid-like creature called the Priestess.

After escaping the crumbling mansion, Simpson and Lee fight their way through the zombies to a nearby church, where they meet Manheim, who is revealed to be still alive. He reveals himself to be the mastermind of the game's events, and tells the agents that the corporation's purpose is to "cleanse" the world of its current status and "reshape" it in their own way. He then sets loose his masterpiece, The Moon, a tree-like behemoth which has abilities similar to that of the Sun from the third game and the World from the fourth, in addition of being able to control wind. They fight it as it gradually became the shape of a humanoid and the size of a 20-story building. Jin then tries to kill it in a desperate attempt by stabbing an iron rod through its head. This, at first, proves unsuccessful, but then a lightning bolt strikes the rod impaled through The Moon's head, thus electrocuting and killing it.

The next morning, Jin and Ethan rest as they watch the sun rise while the former recalls Hal's motto to never lose hope and keep fighting to the end.

Chapter V: Texas Endgame (2030)
In 2030, 14 years after the events of 2016 Poland Incident, a zombie infestation has spread across the world, resulting in the collapse of human civilization and leaving the world in utter desolation. A paramilitary force led by retired NSA agent Paul Armstrong head to a desert wasteland in Texas on a mission to infiltrate the Research Site 26 "Archer", once owned by Dr. Ujazdowski, and investigate its connection to the current state of the world. During the course of the mission, all members of Armstrong's team are killed except for his second-in-command, Captain Trevor Kalanick. Proceeding with the mission, the two agents find the source they sought in a giant laboratory, but are attacked by Death, a gigantic mutant protecting the facility, who kills Trevor. Injured from the encounter, Reagan is assisted by an unknown individual before all communication with him is lost.

Two weeks later, on November 17th, Armstrong's daughter, Elizabeth, and his former partner agent Regan travel to the facility to rescue him. While navigating through the facility, they fend off against hordes of undead creatures, before they encounter Death, whom they fight twice. Later, they fight a deformed mutant sloth named The Fool, and a mutated tendril-covered plant named The Sun. Along the way, Elizabeth muses to Regan how she has to live in the shadows of her well-known father and that she is often the subject of his comparison.

Throughout the game, flashbacks reveal Ujazdowski's motivation in his obsession of studying matters of life and death that resulted in him triggering the Ujazdowski Mansion's outbreak back in 2016; he was desperate in searching for a cure to treat his son, Andrea, who is suffering from a terminal illness. His increasingly unethical methods led him to believe he would be able to change the world for a better future by developing the mutation.

After more fights, Elizabeth and Regan reunite with Armstrong. They are met by the same individual who approached Regan in the prologue, revealed to be Andrea Ujazdowski, who laments his father's experiments that destroyed the world. After Regan reveals on how Andrea tended to him, Armstrong gets Regan to safety, while Andrea and Elizabeth form an alliance to destroy an electrokinetic entity known as the Wheel of Fate. When they reach the giant laboratory, Andrea reveals that the Wheel of Fate is actually his father's body, which underwent a 14-year resurrection process following his death by The Magician, adding that he hacked the program used in its creation some time prior to Elizabeth and Armstrong's arrival, in order to prevent it from being released and destroying the world, saying that the future belongs to the people who are still alive and fighting. The two fight and manage to defeat the Wheel of Fate, which explodes.

In an post-credits scene set 3 years later in 2033, Ethan Mars is sitting on the hood of a muscle car near the Griffith Observatory while smoking a cigarette, loading his gun and getting back on the muscle car.
