The story of James Young, the British man who was outfitted with a prosthetic arm inspired by the Metal Gear series, is now the subject of a BBC3 documentary called Bodyhack: Metal Gear Man. You can watch the two-part special, which runs about 30 minutes, on YouTube.
Bodyhack: Metal Gear Man touches on the accident that left Young without his left arm and part of his left leg, and the efforts of prosthetics maker Sophie de Oliveira Barata to develop a high-tech bionic arm to replace his missing limb. Metal Gear publisher Konami, who paid for development of the prosthetic, branded it the Phantom Limb Project — a reference to Kojima Productions' Metal Gear Solid 5: The Phantom Pain.
Spoilers for Metal Gear Solid 5 abound in the video.
