Konami showed off quite a bit of Metal Gear Solid V: The Phantom Pain during E3 2015. This was shown to those attending E3 and wow is it in-depth. Of course, they couldn't show off everything but you're still looking at 40 minutes of gameplay here. There's stealth, there's combat, there's a dog, there's a mini-Metal Gear, there's combat, there's customization, and just so much more.

From what I understand, another video for this same mission will be released later by Kojima and Konami. As noted, it will feature the same mission as this video but it will show an entirely different route that you can take given the open-world nature of the game. You can also check out these 50 new screenshots and E3 2015 trailer for The Phantom Pain.
