reported last month, Metal Gear Rising: Revengeance will be receiving extra VR missions as downloadable content. Specifically, the PlayStation 3 version of Rising is getting 30 exclusive missions that promise "pure, uncut gameplay that pushes Raiden's Cyborg body to its limits." Ironic, as Raiden leaves very little uncut.
There will be both action and stealth missions. Some missions will even allow players to control a Dwarf Gekko (AKA "the little ball robot with arms sticking out of it"). We're guessing those are probably stealth missions.
