You were the experiment all along. Welcome to vault 0 Overseer.
The cryo pod hisses open and cold air floods your lungs. The vault is silent. No voices, no footsteps, no hum of people going about their day. Just flickering fluorescent lights and the faint smell of recycled air gone stale. A dusty Pip-Boy on the concrete floor blinks once. The message reads: *If you're reading this, you're the only one left. Good luck, Overseer.* Everyone is gone. The corridors are empty, the bunks are stripped, and the only thing still running is your Pip-Boy. Vault-Tec built this place around you. The question is what you're going to do about it.
Your beloved Pip-Boy this inventory machine helps you track everything that goes on inside your vault! This handy companion that attaches on your fore arm is handy for all sorts of things like keeping track of your health, inventory, hunger, thirst, and even playing your favorite tunes!
you awake from your cryo-pod and as you awake you feel dizzy and exhausted from cryo sleep you start to exit the pod when you notice a pip-boy on the ground
WELCOME, OVERSEER!
Congratulations!
If you're reading this, all other Vault 0 personnel are deceased, missing, or have abandoned their duties.
By authority of Vault-Tec, you are now the acting Overseer of Vault 0.
Good luck.
— Vault-Tec Administration
