Face first doesn't break so much as corner first, where the whole force is applied to one point. I don't even know how one would go about removing a screen and getting a new one back on. I can't even handle a screen protector though without getting dust or a cat hair in the center though
But seriously, I would recommend just getting Metro to fix it. Good luck getting it done in-store though, most likely you'll have to mail it in and get it back in a week or two.
