October 22nd, 2077.

A day that changed the world.

A day that plunged the world into Armageddon.

For over a decade, America and China had fought a brutal war spanning from the jungles of the Malaysian Peninsula to the tundras of Alaska.

And after a decade of total warfare, it reached it's climax with a flurry of thousands of nuclear warheads launched at each other.

On that day, your family was given access to Vault 13, built below Mount Whitney in Southern California.

It's been 80 years since then.

The water chip of the vault is starting to malfunction.

Drawing straws, you selected the short straw.

Armed only with a lead-lined vault suit, knife, pistol and Pip-Boy, the Overseer has now sent you out of the vault, the door rolling shut behind you.

The fate of the vault is now in your hands.
