To understand why returning to those ruins matters, you need to look at how each outbreak reshaped the world long before Requiem ever appeared on a release schedule.
TL;DR — Resident Evil Timeline
- The Spencer Mansion incident began the global biohazard crisis.
- Raccoon City became the series’ defining catastrophe.
- Bio-terrorism evolved through parasites, viruses, and fungal organisms.
- Organizations like the BSAA attempted to contain worldwide outbreaks.
- Resident Evil Requiem focuses on the long-term consequences of those events.
Resident Evil and the Spencer Mansion Incident
The first Resident Evil feels small in scope compared to what came later, yet everything begins there. The Spencer Mansion incident exposed Umbrella Corporation’s secret research into the Progenitor Virus.
Oswell E. Spencer and James Marcus twisted that discovery into something marketable and lethal. The T virus was never an accident — it was a calculated step toward weaponizing biology.
Chris Redfield, Jill Valentine, and Rebecca Chambers survived the nightmare. Meanwhile, Albert Wesker’s betrayal proved that the real danger was not just the creatures in the dark, but the people funding them.
Resident Evil 2 and Resident Evil 3
When Resident Evil 2 shifts the story to Raccoon City, the scale changes completely. Leon S. Kennedy arrives on his first day as a police officer while Claire Redfield searches for her missing brother.
The T virus spreads through contaminated water, while William Birkin’s G virus introduces uncontrolled mutation that refuses to stop evolving. Sherry Birkin becomes central to the crisis, and Ada Wong works behind the scenes with mysterious motives.
Resident Evil 3 takes place during the same catastrophe but follows Jill Valentine as she is relentlessly hunted by Nemesis, a bio-weapon designed to eliminate surviving witnesses.
The government ultimately launches a missile strike that destroys Raccoon City, an event that becomes the defining trauma of the entire franchise.
Resident Evil 4
Umbrella collapses, but the research culture survives. Resident Evil 4 moves the story to rural Spain and introduces Las Plagas, a parasite capable of controlling its host while preserving consciousness.
Leon returns as a government agent, confronting a threat that feels different from the mindless infection of earlier games. Meanwhile, Albert Wesker continues manipulating events from the shadows.
The shift marks the moment when bio-terrorism becomes a global commodity rather than a secret corporate disaster.
Resident Evil 5 and Resident Evil 6
Resident Evil 5 returns to Africa and explores how deeply the original Progenitor research shaped later experiments. The Uroboros virus represents forced evolution taken to its extreme.
The confrontation with Albert Wesker finally ends one of the longest-running threats in the series.
However, Resident Evil 6 reveals that removing one architect does not end the system. The C virus spreads across major cities, while Neo Umbrella weaponizes bioengineering on a global scale.
Leon, Chris, Ada Wong, and Jake Muller fight across a world where outbreaks are no longer shocking — they are expected. The BSAA emerges as an international response force attempting to contain these disasters.
Resident Evil 7
Resident Evil 7 narrows the focus again. Instead of trained agents, players follow Ethan Winters, an ordinary man searching for his missing wife.
The threat comes from The Connections and their new biological weapon: the Mold. Unlike traditional viruses, the Mold manipulates perception and memory.
Eveline turns the Baker family into unwilling hosts, transforming the horror into something deeply personal and confined.
Resident Evil Village
Resident Evil Village expands the story again. Mother Miranda and the Megamycete introduce a fungal organism capable of storing human consciousness.
Miranda’s connection to Oswell E. Spencer quietly ties this storyline back to the original Progenitor research, linking the franchise’s past and present.
Ethan’s sacrifice to protect Rosemary Winters highlights the generational consequences of decades of bio-weapon experimentation.
Raccoon City Was Not the End
Resident Evil Requiem focuses on what came after, not how it all started. Umbrella may no longer exist in name, but its influence remains everywhere.
Every new organization, every mutated strain, and every survivor shaped by Raccoon City traces back to the decisions made during those early experiments.
Grace Ashcroft represents that fallout. Her family survived the original outbreak, and now she faces the long-term consequences of events that happened decades earlier.
Instead of chasing new secrets, the story centers on the lasting scars of the biohazard era — and the people still living with them.
