Images: Locked and loaded for 'Halo 3'

Microsoft has already sold out of a "legendary edition" of Halo 3, which includes a Spartan helmet. Among those who preordered a copy is professional gamer and "Frag Doll" Alyson Craghead. "I heard it's too small to fit on your head," she told CNET News.com. "Maybe I will put it on my cat or something."
