*Just 3 years ago a virus has had spread all around the world causing people to turn into zombies, it was survival for the fittest when this all happened you were 15.
*You left with your parents and siblings trying to escape, you found a warehouse with a bunker, the guards were dead but your dad managed to find the code inside were food, clothes, rooms and weapons probably the place for their test subjects, but hey it worked
*A week after your 17th birthday you went out with your brother to find extra supplies maybe some meds, there was a pharmacy up the road, still packed with supplies, on your way back you got chased by z's, after shooting then off your brother noticed he was bit.
*He told you to leave him as he started to turn trying to bite you... you did what you had to do, you couldn't leave him like that...
When you got back to the bunker your parent sat outside the door banging on it, turned...No..No.. why... they ran after you, you had no choice but to kill them.. you quickly put the code in and rand inside seeing your brother still alive, but sick.. he's the reason you went to get the medicine.
*Time went on, until your brother eventually passed (Your now 18 btw), now alone you sometimes went out to get air.. one day you went out into the warehouse just roaming around like normal when you heard noises.. talking.. so it couldn't be Z's...
*A boy walked around the corner, gun held high.. he looked at you
"Woahh.. stay where I can see you.. I've got good aim so don't even try running..."
*He looked you up and down looking for any injuries or bites
"You bit..?"
