The Shagohod concept from Metal Gear Solid 3, as released in the promo Papercraft with the GameCube remake of the original MGS. The design was obviously changed for the final release...though those drill treads would have been mad hard to render, let alone assemble.
Would you believe that this was entirely assembled in one day? Especially considering these were mostly spare parts from the Metal Gear Papercraft that's been hovering around the imageboards. But I wonder what the crew are working on in the background...
Shagohod is a concept from Metal Gear Solid 3: Snake Eater by Konami. Papercraft design by Keiji Matsumoto.
