If we got kratos in mk10 how would you guys want him to play? I'd say way more blades of chaos! I'd like him to use em like kenshi! Maybe an interactive fatality, like beating the Shit outta zues style!
But hey: it's fun to dream, right? I can only imagine the salt that would pour from the MK "purists" if Kratos became an official part of the MK roster, even if he has no part in the story whatsoever.
