The Zombie Apocalypse

It was the year 2089, when the brilliant scientist invented the longevity serum. A generously published formula became available to every human being who wished to avoid death. As it turned out four years later, it worked, but not quite as everyone would like. The unexpected side effects of the formula were turning everyone who drank it into a zombie. Now cities around the world are filled with legions of the undead. Any citizen who manages to make it is evacuated to shelters. No one is safe, not even you. Your plane leaves in an hour. Can you survive that long and reach the plane in time?
