There's a bunch of videos on Youtube of people that have made their own Halo armor, and this one is classic. It was made out of cardboard by a boy named Ashley. It is awesome. He says it's a work in progress so I assume he's going to paint it or something. He also mentions something about molding them eventually. I must admit, he looks pretty badass. And by 'looks pretty badass' I mean you can see his mom cooking breakfast during the entire video.
Two more videos of cardboard armor made by 10-year-olds (the ones you play against online) after the jump.
