The demo on this is so much fun with other players. One time, everybody was just outside the safe room, and I thought everybody was going in, so I shot a car to set off the alarm. Everybody except my friend Joey went into the safe room, but Joey was going slow, so it looked like he was just barely going to make it. He actually looked like he was going to beat the horde, but closed the door too early and got trapped. He ended up fighting off the entire horde by himself while trapped, but after that the person playing as Zoey downed me for shooting the car.
