Tokyo Game Show 2011 was the perfect opportunity to reveal the latest MGS: Snake Eater 3D trailer. In it, Solid Snake is doing what he does best, kicking ass and squatting. I'd say he's equally good at both activities. The trailer also demonstrates how the 3DS can be used to balance Snake.
Metal Gear Solid: Snake Eater 3D does not have a confirmed release date but early 2012 is looking likely.
