Here are two interesting photos Kojima posted today. First, a picture of Metal Gear Solid V: Ground Zeroes’ menu screen in Russian language.
The audio of the game won’t be in Russian, only the menus and subtitles.
Secondly, a photo of Yoji Shinkawa working on a Metal Gear Solid: Peace Walker artwork (possibly meant for the PW novelization that will be included into MGS Premium Package in Japan).
