Master Chief is a big man, but he wasn't always big. He was once a boy, called John! And when John was a boy - no, a baby - then maybe these Halo helmets would have fit him.
Special effects house WETA, who at one stage were signed up to do the Peter Jackson Halo movie, will next month release this range of little commemorative helmets from the Halo universe, which are 1/4 scale and cost $US60.
There will be three available in limited runs of 300 each: Master Chief, an E.V.A. and a C.Q.B. helmet.
