Sideshow will soon be releasing this enormous piece based not only on Halo's Master Chief, but on what looks like his original design from the very first Halo, all the way back in 2001.
While it's called a "figure", poseability seems to be severely limited, but at $400 and weighing a ton, it's not like you're going to be taking it down off the shelf to play with it.
Pre-orders for the piece open later this week at the link below.
