To celebrate the launch of Metal Gear Rising: Revengeance, Konami has promised everybody a free cyborg ninja. It's based on the design of the original Gray Fox from Metal Gear Solid, and is equipped with the super-powerful Fox Blade.
Take a deep breath: The cyborg ninja is - unfortunately - only in-game, but it's pretty exciting nonetheless. Konami has confirmed that each copy of MGR: Revengeance will include a free DLC code to unlock a brand new body for you to play the game with. You'll get your very own Fox Blade - completely upgradeable - and generally run around the place lookin' pretty bad-ass. That's really all there is to it.
