Apocalyptic

Its been 18 years since the wild brain cell controlling virus attacked the world, leaving the remaining survivors running around in their respective states while under high control.
Pharah, a 16 year old girl, who was born during the apocalypse, has donated her blood, like everyone else in Florida, to find a cure, but little does she know, she was born with it, and now the military has asked her and a few more people to wipe out the remaining Rottens and give the cure to the remaining survivors.
