The Origin: Progenitor Virus and Umbrella Birth

Everything started in the mid-1960s. A rich arrogant man named Oswell E. Spencer gathered scientists to play god. They discovered something called the Progenitor virus in Africa. This virus could force evolution in humans. It could make superhumans. It could also kill almost everyone exposed to it. High mortality rates meant the virus needed work.

Spencer needed money for research. The United States military wanted bioweapons. A deal was struck. Umbrella Corporation formed as a pharmaceutical front. Behind the scenes, they developed viral strains for warfare. One strain became infamous. Everyone knows the T-Virus. Tyrant virus. The thing that turns people into zombies. This foundation created thirty years of horror.

Resident Evil 1: The Mansion Incident

Fast forward to the late 1990s. Raccoon City sits in the shadow of the Arklay Mountains. An old mansion hides in those woods. This mansion contains a secret underground laboratory. Local animals and people start dying horribly. The Special Tactics and Rescue Service investigates. STARS sends their best team.

Albert Wesker leads Alpha Team. He looks like a hero. He is actually a traitor working for Umbrella. Two rookies named Chris Redfield and Jill Valentine survive his betrayal. They uncover the T-Virus experiments. They fight mutated creatures. They escape the Spencer Mansion alive. But the T-Virus leaks into Raccoon Citys water supply. The outbreak begins.

Resident Evil 2 & 3: Raccoon City Falls

Resident Evil 2 happens days after the mansion. Leon Kennedy arrives for his first day as a Raccoon City police officer. Perfect timing for the apocalypse. Zombies eat his fellow officers. The city burns. He meets Claire Redfield, sister of Chris from the first game. She searches for her missing brother. They team up to survive.

Leon encounters Ada Wong during his escape. She claims to be FBI. She lies. She is a mercenary after the G-Virus. This virus is worse than T-Virus. It comes from Doctor William Birkin. Birkin injected himself and mutated into a monster. Leon also meets Sherry Birkin, Williams daughter. She carries the G-Virus inside her. They reach an underground facility called NEST. Claire finds a vaccine. Sherry gets cured.

Meanwhile, Jill Valentine fights her own battle in Resident Evil 3. She navigates the same collapsing city. An Umbrella mercenary named Carlos Oliveira helps her. But Umbrella sends their ultimate weapon. Nemesis. This monster stalks Jill relentlessly. It infects her with the T-Virus. Carlos retrieves a vaccine and saves her life.

The United States government makes a decision. Raccoon City cannot be saved. They drop a nuclear bomb. The city becomes a crater. Leon, Claire, Sherry, Jill, and Carlos escape before detonation. The T-Virus outbreak ends with a mushroom cloud.

Outbreak Series: Alyssa Ashcrofts Investigation

Two games called Outbreak happened during the Raccoon City chaos. These games introduced Alyssa Ashcroft. She is a reporter for the Raccoon City Times. She is also Grace Ashcrofts mother. This connection matters deeply for Requiem.

Alyssa investigates a private hospital on the city outskirts. She uncovers suppressed memories from five years earlier. Umbrella conducted illegal experiments there. They tested drugs on patients. They created monsters. Alyssa witnesses the truth. She escapes the city alive. She writes an explosive exposé. Her article helps destroy Umbrella Corporation publicly. Grace inherits her mothers investigative spirit. She also inherits her mothers trauma.

Post-Raccoon: Code Veronica to RE4

Resident Evil Code Veronica takes Claire to Rockfort Island. She searches for Chris. She finds Alfred Ashford and the T-Veronica Virus. Chris rescues her. They defeat Alexia Ashford. Albert Wesker returns from the dead. He reveals he faked his death and gained superhuman powers.

Umbrella finally collapses. Lawsuits destroy them. Regulations bankrupt them. But the viruses survive. Bioterrorism becomes the new threat. Leon makes a deal with the United States government. He works for them. They give him and Sherry freedom. This brings us to Resident Evil 4.

The President of the United States has a daughter named Ashley. Cultists kidnap her in Spain. Leon gets the rescue mission. He fights Las Plagas parasites. These things control human hosts. He finds Ashley. He finds Ada Wong again. She still works for mysterious employers. Leon survives and returns home. This mission cements him as the governments top agent.

RE5 to Village: The Modern Timeline

Between RE4 and RE6, several games happen. Resident Evil Revelations shows Chris and Jill fighting bioterror on the high seas. Resident Evil 5 sends Chris to Africa. He finally kills Albert Wesker for real. Wesker dies in a volcano. No more comebacks.

Resident Evil 6 introduces Jake Muller. He is Albert Weskers son. The game also establishes two key organizations. The Department of Security Operations. The DSO. Leon co-founds this government branch. Sherry works there as an agent. The Bioterrorism Security Assessment Alliance. The BSAA. Chris co-founds this with the United Nations. These organizations fight the bioweapons Umbrella left behind.

Resident Evil 7 and Village shift focus to Ethan Winters. He faces the Mold. This fungal infection seems unrelated to previous viruses. But Mother Miranda created it. She inspired Umbrella founders. The Connections crime syndicate continues this research. They use the Mold for mind control experiments. The BSAA investigates them. This pushes the events of RE7 and Village into motion.

Requiem Setup: Leons Final Mission

Now we reach the present day for Resident Evil Requiem. Years have passed since Raccoon City exploded. Survivors thought they escaped clean. They were wrong. Prolonged T-Virus exposure causes a new disease. It does not mutate victims. It kills them slowly. Leon Kennedy has this disease.

Leon searches for a cure. This mission brings him back to the ruins of Raccoon City. He meets Grace Ashcroft there. She is Alyssas daughter. She is an FBI analyst. Someone targets her. Nefarious forces want her dead. Leon protects her. Together they face new horrors in the place where everything started.
