Introduction to the Fallout Universe
The post-apocalyptic universe of Fallout is one of the most rich and intricate settings in video game history. Built upon an alternate history where 1950s retro-futurism meets atomic horror, the franchise spans hundreds of years of destruction, survival, and factional warfare across the former United States. Understanding the lore requires looking beyond game release dates and examining how events unfold chronologically in the wasteland.
From the world-ending nuclear exchange known as the Great War to the rebuilding of civilization centuries later, this complete timeline covers the major events and places every entry in the franchise—including Fallout 76, Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, and Fallout 4—in precise order.
The Pre-War Era and the Divergence (1945–2051)
The timeline of Fallout splits from real-world history after World War II. Instead of inventing the microchip, scientists in the Fallout world focused heavily on nuclear technology and vacuum tubes. This created an advanced atomic age aesthetic where nuclear-powered cars, domestic robots, and laser weaponry became reality, all while culture remained culturally frozen in 1950s Americana.
Key events during this era include:
- 1945: The Divergence occurs. Historical paths begin to deviate from real-world history.
- 2020s–2040s: Rapid technological advancement leads to nuclear-powered home appliances and early artificial intelligence development.
- 2051: Fossil fuels begin to deplete rapidly across the globe, setting off global conflict.
The Resource Wars and the Great War (2052–2077)
As global natural resources dwindled to critical levels, world powers engaged in desperate military conflicts known as the Resource Wars. China invaded Alaska to claim the world's last remaining oil reserves, leading to the Anchorage Reclamation campaign led by the United States military.
During this period, Vault-Tec Corporation was commissioned by the U.S. government to build 122 massive underground shelters called Vaults. Officially designed to protect citizens from nuclear war, many Vaults were secretly commissioned as unethical social and biological experiments on human subjects.
On the morning of October 23, 2077, the Great War erupted. Within just two hours, nuclear warheads were launched worldwide, obliterating major cities and destroying modern civilization. Humanity was cast into darkness, and the age of the Wasteland began.
Chronological Timeline of the Fallout Games
2102: Fallout 76
Taking place just 25 years after the bombs fell, Fallout 76 is the earliest entry in the universe chronologically. Vault 76 opens on Reclamation Day in the hills of Appalachia (West Virginia). Survivors step out into an untamed world infected by the Scorched Plague. Dwellers must rebuild society, neutralize nuclear launch facilities, and establish early wasteland settlements long before major power factions dominate the continent.
2161: Fallout
Set 84 years after the Great War, the original Fallout introduces the Southern California wasteland. A resident of Vault 13, known as the Vault Dweller, is sent to the surface to find a replacement Water Chip to save their home. During this quest, the Vault Dweller uncovers a major threat: The Master, a mutated mastermind creating an army of Super Mutants using the Forced Evolutionary Virus (FEV). The Vault Dweller defeats The Master, saving humanity's remnants in California.
2197: Fallout Tactics: Brotherhood of Steel
Taking place in the Midwest, Fallout Tactics: Brotherhood of Steel follows a rogue rogue faction of the Brotherhood of Steel expanding across Chicago and the surrounding plains. They fight against raider tribes, mutant warlords, and an aggressive rogue AI known as the Calculator.
2241: Fallout 2
Set 80 years after the events of the original game, Fallout 2 stars the Chosen One, a direct descendant of the original Vault Dweller. The Chosen One sets out from the tribal village of Arroyo to secure a Garden of Eden Creation Kit (GECK). The journey leads to a confrontation with the Enclave—the remnants of the corrupt pre-war United States government operating off the California coast on a giant oil rig.
2277: Fallout 3
Shifting the narrative focus to the East Coast 200 years after the Great War, Fallout 3 takes place in the Capital Wasteland (Washington, D.C.). The Lone Wanderer leaves Vault 101 to search for their father, James, who is working on Project Purity—a massive water purification device. The protagonist fights off the returning Enclave forces alongside the Eastern chapter of the Brotherhood of Steel to secure clean water for the region.
2281: Fallout: New Vegas
Four years after Fallout 3, Fallout: New Vegas returns to the American West in the Mojave Wasteland. A courier shot in the head and left for dead survives and seeks revenge. This personal vendetta escalates into a massive three-way battle for control over Hoover Dam and the Las Vegas strip between the New California Republic (NCR), Caesar's Legion, and the enigmatic Mr. House.
2287: Fallout 4
Set ten years after Fallout 3, Fallout 4 unfolds in the Commonwealth (Boston, Massachusetts). The protagonist, known as the Sole Survivor, emerges from cryogenic stasis inside Vault 111 after witnessing the murder of their spouse and the abduction of their infant son, Shaun. The search uncovers the mysterious Institute, a secret organization manufacturing synthetic humans (Synths), forcing the player to choose the fate of the Commonwealth.
