I know people think this kind of stuff is fake but this isnt. All you have to do is not look at the box(turn your back to it) and dont look until it's finished. Simple.
Really doubt this would work. Developers would probably just make it so that the box is actually random. It would be more work to have to add more code to check if you're looking at the box, then have to decrease the likeliness of a select group of weapons that are considered, "Suckish", to appear. If you're using the box on a high round and there are zombies chasing after you. It would be easier to turn around and shoot the zombies. It would be harder to look at the box. Why would the game reward you for doing something that is easier (turning away and shooting the zombies), but not reward you if you look at the box (which is harder).
Not familiar with PTG. Sorry if my post sounded offensive by the way. Was just stating my opinion. It could be true, but eh. I just don't think it would be true.
