This is a 1:1 scale scratch-build of the helmet worn by the Master Chief (aka SPARTAN-117) in the popular HALO series of video games available for the Xbox/Xbox 360 console system. Build based on a low-definition paper model extrapolated from the in-game model, and mainly comprised of layered sheet styrene. I plan on installing LEDs and exhaust fans, once finished. The second pic simply shows a comparison between my helmet and the helmet that was included with the Legendary Edition of the third game. As can clearly be seen, the Legendary helmet is not quite 1:1 scale.
