The Vault
The year is this year, the time is now, the location is here. However different our timelines have diverged in the past, this particular timeline has gone askew and ended with the human race going on a suicidal rampage against one another, eventually turning into a worldwide nuclear war.
You are one of the survivors of the war, however, you are not safe yet. Your town was hit directly from an atomic bomb, and while you were a fair distance from the epicenter of the blast, radiation has begun to cover the whole town.
Those who survived and were smart enough to research the upcoming war knew that the vault in the bank was the only chance of surviving the eventual radiation that would bear down on you. You have proceeded to the bank to find they have already locked the vault.
Your life will soon be over if you do not find a way into the vault. There may be some objects in the nearby area that will help you enter the Vault - even forcefully. But beware, survivor: all actions have consequences.
The Vault (Entrance)
The entrance to the vault is basically a rectangular room, with the door to the vault, tons of solid steel, on the wall. Due to the lockdown situation, the door is locked, the opening controls have been locked and the door can only be opened from the inside.
