Let me get something straight I'm all up for a zombie apocalypse but not every apocalypse has to have zombies. Mine will not.
Now of I still have your interest this is my idea;
It's May 12 2034, the world has fallen. It started a year ago in a lab, a group of scientists were trying to find a cure for the rare Empolo virus. They had found a cure or they thought. One of the scientists had contracted the virus in testing and the cure was then tested on him. It seemed to erase the virus having the person not show any signs of having it. The scientist was released from solitude and went to work around the lab then things started happening.
This scientist would stay at work for days on end not eating anything, most would say he was just dedicated. When questioned he would stare into space till the person left, then things got weirder. His hair turned gray and started to fall out of his head his nails stopped growing and turned purple, he grew wrinkles and rested a lot. At this moment the cure was being sent out to everyone as a vaccine. The original scientist died a week after he was given the cure, he died of old age at the ripe age of 23 but his bones said he was 98.
Week after week people dropped dead like flies all of old age. People who didn't locked them selves inside and started robbing store. The world's rulers fell to the virus and soon the world was a waste land. Vegetation grew over the abandoned parts of town and were people where it grew. The news made a final broadcast on July 5, 2033.
It described what was happening and then went over to one of the original scientists who was very anxious. He told of how the discovered that the vaccine didn't get rid of the virus it made it stronger and that people with it were to go to the pit. The pit is a gigantic grave yard in which all the victim's are to be played to rest. Then they said it spread by water and that the virus couldn't survive heat and water could only be drunken when it was warm or it had no contact with the air when cooling. Then the broadcast cut off. Men burst in every house dragging out dead body's and anyone with symptoms and dropped them in the pit. Those who were still alive were scared and stocked up on everything, before the power went out.
It's been a year since Empolo virus broke out and the men in yellow suits have stopped coming to collect bodies. Your a survivor of this outbreak how would you survive this terrible apocalypse.
That my idea more May be added as I answer questions.
