While we are on the.subject I got a question about pulling objects into you on a single file pipe. I don't remember which level I was. It was one of those levels with a floating platform. But there.was.a.large cement pipe where you can stand in. I've seen people in there with a soda machine dragged into them. The zombies can't get.him unless the pull the.object out. But he's firing and pulling back at the same time. That is considered legal?
