Details? Nothing as of yet, though God of War designer David Jaffe has been offering his thoughts onTwitter. On Kratos' fatalities, he says "[He] would have a F*CKALITY and f*ck the SHIT out of Sonya AND Katana at the same motherf*cking TIME!!!!" He did not use asterisks, but he did add a smiley to emphasise the jovial nature of his idea.
Above: Kinectimality. Flailess Victory, etc.
He also suggested (and this is a pretty cool idea actually) that "Kratos should reach out and pull the f*cking MK classic Narrator into the game and gut the f*cker! Oh, or rip the head off 'toasty!' guy!" That one, I'm down with. It's perfectly fitting with Kratos' "WRRRRRRRAAAAAAAUUUGHHEVERYBODYDIIIIIIES!" persona. Let's face it, this guy just isn't stopping until there's not a single person or thing left alive in his field of vision.
The question remains though, of whether the 360 will be getting a similar exclusive character. Nothing has been mentioned yet, but who would you want? Marcus Fenix as a bulky brawler with chainsaw melee? A Crackdown agent to back up Sonya Blade and Jax? Avery Johnson gone postal? Let us know.
