ALFRED, N.Y.-- "I took my belongings, walked downstairs and darted as fast as I could and 13 to 15 zombies started running after me," said Rosemarie Fraioli, an Alfred University freshman.

Fraioli isn't talking about a dream but real life playing the game Zombies versus Humans. In the game, the humans use Nerf guns to stave off a zombie attack. Tuesday, one of those guns sparked a campus-wide lockdown at Alfred University.

"One faculty member saw one of our players walking through an academic building. And we think they just glimpsed one of the Nerf guns and thought it was a real gun," said Alex Geddes, the game's organizer.

It was the black and silver handle of one of the Nerf guns that was mistaken for a real gun. But according to the rules of Zombies versus Humans, players purposely use guns that don't look real to prevent confusion and make sure everyone stays safe.

"They are intentionally bright colors so that you know they are a plastic toy and not a pistol," Fraioli said.

Even so, there was confusion and the game at Alfred is off for now. But Norm Pollard, the Dean of Students, said the game has benefits and could come back in a modified way.

"We don't want to have a knee-jerk reaction and automatically condemn this activity but see if there's a way we can work together that deals with the problems and still has a positive outcome," said Pollard.

Organizers said they're eager to work with university officials.

"The last thing we want to see is this generate bad publicity for this game here and on other campuses," Geddes said.

A few other schools have banned Zombies versus Humans outright. But at Alfred University, it looks like players could get the chance to fend off another zombie attack.

The dean declined to comment on whether Alfred University will take any disciplinary action against the student who caused the lockdown.
