remove head

You drop the book and run over to an old school paper cutter. You yank the arm off the contraption and know how a sharp weapon to decapitate your victims with. Fifty feet away you spot a computer lab. You run towards it, lopping off the heads of any zombies in your path. You access the campus website and see a post by one of the science professors. The government has given him a grant to test a new anesthetic drug on mice. Somehow it got into the school's free flu vaccine and has turned the student body into zombies. There is a cure but it's in the science building's labs. Do you go get the cure or get the hell of campus?
