Kratos will be joining Mortal Kombat as an PS3 exclusive character. We've got the first gameplay trailer showing of the God of War's unique skill set. I don't know where he puts all those weapons in that loincloth he wears but he sure seems to have plenty of them. Kratos will not be playable in the story mode.
I do have to wonder, will you be able to perform fatalities on Kratos? Will Scorpion be able to cut him in half ?
