You awaken in a claustrophobic environment, lit by fluorescent lights that cast a cold glow on the metal walls around you. This is Vault 117, an underground shelter designed to protect the chosen few from the horrors of the nuclear war that ravaged the surface. You've lived your entire life here, safely, surrounded by advanced technology and rigorous security protocols.

However, recently, conditions within the Vault have begun to deteriorate. Technical problems, scarcity of resources and tensions between residents became unbearable. The Vault administrators have decided it's time to explore the outside world, in search of supplies and, possibly, a new home. You have been selected to be one of the pioneers on this dangerous and crucial mission.

With a mixture of fear and excitement, you prepare to leave the Vault for the first time. Equipped with a Pip-Boy, a portable device that will help you navigate and survive the Wasteland, you head to the immense steel door that protects the Vault. As you turn the large lever, a thunderous sound echoes through the halls as the door begins to slowly open, revealing the darkness and unknown vastness of the outside world.

As natural light floods the Vault for the first time in decades, you take the first step outside, ready to face the dangers and opportunities of the Wasteland. The air is different, charged with the promise of adventure and challenge. From this moment on, your journey into a world transformed by nuclear destruction begins. The fate of many may depend on your actions and decisions. Welcome to the new world, survivor.
