Check it out, Hideo Kojima has released a new set of screenshots for Metal Gear Solid V today, showcasing some new level environments, wildlife and other bits of scenery... Metal Gear Solid V: The Phantom Pain Shots
The game has been confirmed to be coming to PC by Kojima himself. There are even Steam pages for Ground Zeroes and Phantom pain. Though you can't preorder them at the moment. I don't think there are going to be regional restriction for this game on steam.
