After School MOWDOWN

Today in one of the schools in the city happened very big trouble in chemistry class one of the students poured chemicals on the floor, all breathe and started to turn into bloodthirsty zombies. And now they will only be able to stop you, but you do not even have a weapon, and so the only chance to save the earth is your car with the help of which you can crush all who run from the school without giving them a chance to infect other people this terrible disease.
