Having made sure the air was finally breathable outside, I would slowly open the enormous rusty door looking for possible threats and when I felt safe, I would scream on the top my lungs, while crying of happiness - I had my own post apocalyptic world to explore, trying to rebuild and repopulate earth (except Australia, I'm fairly confident they weren't hit by any of this).
After 199 years stuck in hibernation pods, the computer running Vault 84 decided it was time to release its occupants, since the radiation levels were steadily lowering, enough to be survivable in about 12 months. Little did it know that most of us were not going to wake up, ever. One of the nukes had penetrated the vault and destroyed most of it.
Luckily (I'm a die hard optimist) me and 3 others had survived by sheer luck because our pods were in the 'poor' end of the vault, near the heavy machinery, which withstood the brunt of the explosions and also shielded us from the ensuing radiation.
For the past year we had struggled to survive on what little was left of our supplies and all the radroaches and mole rats we could get our hands on. Deborah, our doctor, actually tried to grow edible and pharmaceutical plants, but was only successful with a few hallucinogenic mushrooms, which we tended to save for special occasions.
Fortunately water was easy to come by thanks to our faithful water processing plant. Having Fred, a mechanical engineer, with us proved invaluable, keeping our life sustaining equipment in top shape.
Staying so long in the confines of our small section of the vault took a heavy toll on us, particularly because the only source of entertainment were Facebook games. I was able to connect the vaults network systems to a makeshift satellite antenna to connect us to the world wide web. Surprisingly the only servers we could still access belonged to the dictator Zuckerberg, who had bought a significant part of Alaska to keep his data centers cool, and had somehow survived this, making enough posts a day to make it obvious he wasn't quite sane anymore. Sandra was hit the hardest since she did not have an account and kept getting high on mushrooms, day in day out.
I wasn't sure the others were actually happy to leave the vault, but it would prove to be the happiest day of my new life...
