that ones been around for ages, theres about 15 different ways you can get your guy through the walls, theres some secret rooms on some of the maps even. So much fun, also in most cases once your threw the wall, to get another gy through you can either a) grab him from behind and drag him through or b) jump on his head and have him hold forward to the direction of the wall and when he gets back up off the ground, he'll go through.
I wish my xbox was working, I love SP.
<EDIT>
Just watched the vid
nvm, thought you were talking about actually getting through the wall. Thats awesome
