The demo itself takes place during the first chapter, letting fans get to grips with this new way of playing Metal Gear. Revengeance is from both Kojima Productions and Platinum Games.
This instalment in the series also brings back Raiden as a playable character, as it follows his journey as a cyborg ninja. At least he's not naked in this one... probably.
Metal Gear Rising: Revengeance releases on Xbox 360 and PS3 February 19th in the US, 22nd in EU.
