Earlier today at Microsoft's E3 concert briefing, Hideo Kojima came on stage to announce the latest in the Metal Gear Solid line of games, Metal Gear Rising.

Metal Gear Solid 4 has always been rumoured to be arriving on the Xbox360, even after its release and the constant denial from Kojima, who is the mind behind the whole Metal Gear series, that Metal Gear Solid 4 would not be coming to the Xbox 360.

However, while the rumours were seemingly wrong about Metal Gear Solid 4, what has been announced today is that Metal Gear Rising will be coming to the Xbox 360 as a first for Microsoft's Xbox platform.
Very little is known about Metal Gear Solid Rising, what was shown was only a small teaser which contained and ended with an image of Raiden, well known in the MGS franchise since its second incarnation.

The trailer then ends with another character, Colonel Campbell from previous games, announcing that "Raiden is back"

For those who don't know much about the character, Raiden was the main character you played in Metal Gear Solid 2, to much dismay I might add as he was mostly disliked for his look and character personality, the player wanted to play Solid Snake, but got stuck with Raiden.

He later made an appearance in Metal Gear Solid 4 this time returning completely transformed. No longer was he the white haired boy that most hated, but instead had become a Cyborg Ninja that everyone now came to love, not only that, wished they could play.
This now seems to be the case with Metal Gear Solid Rising, players will finally get to play with the Cyborg Version of Raiden found in Metal Gear Solid 4.

It is unknown if this game will be Xbox360 exclusive or if the game will be coming to the Playstation 3 as well as no details as to any more platforms have been released.
The trailer that was shown at Microsoft's E3 press Conference follows.
