At the beginning of this month, Kojima provided a few small details via Twitter on some of the gameplay elements that will be implemented in Metal Gear Solid V: The Phantom Pain. You will be able to smash enemies into walls, and take their weapons without it being ID restricted as was the case in Metal Gear Solid 4.
Crawling will make a return as well, something that was absent in Metal Gear Solid: Peace Walker.
Not like Manga like "PW", it will be "CQC enemies into walls!" for real.
