It is a old leaked clip , their is a slightly newer ( better graphics ) and slightly different clip that was at E3.
( for those that don't know ) This is the 3rd game ( The Last Guardian ) from the team behind ICO and Shadow of the Colossus , these are special games ( granted not for everybody ) that work on a emotional and isolated level. Some people wouldn't call them fun , but meh each to their own.
Nothing more than the trailer is know at this point , the game is due for release in December 2010.
It looks to me like a adventure game , and the young lad finds and befriends the rat type creature , together they go through the world , and need each others help to reach their goals...stunning!
You can stick your MW2 up your arse , i'll take this any day of the week. hehe
