Can anyone tell me why these strange boxes that look like the UPS man delivered a package to the front doors or driveways of all the houses appear on the Nuketown Zombie map. I was playing split screen and we could both see a box on the diveway but the people we were playing with could not.
Another time cardboard boxes appeared at the front door of every house. They don't SEEM to do anything but I don't see anyone else talking about them!
