During Microsoft's press conference, the company revealed a deal with Crytek to release a game exclusively for the Xbox 360. That game was codenamed Kingdom and you can catch the trailer after the break.
Kingdom seems to have been in development for at least a year, with Crytek trademarking the name in April last year, before showing off a demo at GDC in the same year.
Not much else is known about the game. Well, apart from the fact it looks awesome.
No date yet.
