The new God of War game for PlayStation 4 is almost here. One of the first things you may notice is that the combat is changed significantly from past entries in series. We spoke with game director Cory Barlog today about these changes and why the developer, after seven games in the series, thought now was the right time to shake things up with something new.

Asked directly why they changed the combat, Barlog replied, "Because we have made seven games with that combat system."
