Metal Gear Solid 5: The Phantom Pain is leaning hard into its open world structure, and the latest video makes a point to show just how open it is. The 31-minute demo (via RPS) shows some of the areas we saw recently at E3, but with a different approach. Grab a popcorn and some soda--it's a long one--and check out the playthrough below. It's in Japanese for the time being, but we'll add the English-language version as soon as it pops out from the cardboard box it's hiding under.
