Konami formally announced Metal Gear Solid: Peace Walker’s release date in Japan and if you haven’t heard it’s March 18, 2010.
The news came with a batch of screenshots and a reminder the game utilizes Yamaha’s Vocaloid technology. You know Hatsune Miku? She’s a Vocaloid character. That software, but not necessarily Hatsune Miku, will be used to add singing to the Metal Gear Solid: Peace Walker.
