The spot marked in red border line, the 1st picture, is the illegal spot I am posting here for discussion and comment. I have never seen anyone playing this spot before, but, I was able to get onto it today. There are two methods in getting up there, if you could refer to 2nd picture here. One way is having another person help boost you up there, sort of like illustrated with the arrows in the picture. The next method, I can't really illustrate so please try to follow, is shifting the crate (very tricky to do) to a preferable position, where it is tilted over the ladder, then use that to boost you up there. The thing here is, there is only one single way for zombies can be boosted up there, as represented in the 3rd picture. If zombies try to boost anyone from any other sides it would not be possible in my view. Since there is only one way up, it is also quite easy for the survivors up there to shoot away the zombies. Since, the illegal spots are impossible spots, I say this spot are definitely impossible. Also, the boards underneath, unlike the other towers on that map cannot be penetrated by cutting, nor is it movable. Take a look or try the spot yourselves, and let us all know what you think of that spot. Though this spot I had never seen anyone playing there, it might not be needed to be posted.
