The father of Metal Gear Solid, Hideo Kojima, has revealed in his most recent audio blog that a new Metal Gear Solid game is in the works for Sony's PSP handheld. This new MGS will be part of the official storyline and will NOT be a card-battle game like Metal Gear Acid. It'll be a third-person action game, just like the console MGS games are.
Kojima revealed a few key details about the game, which will apparently ship sometime in 2007 to coincide with the 10th anniversary of the first Metal Gear Solid.
Game Details
Unfortunately, it looks like the game isn't far enough along for the company to present it during the Electronic Entertainment Expo next week, so we'll have to be patient for a few months until Konami reveals more info and unleashes the first screens of the game.
