“I heard you did battle with beasts, scoundrels, princesses, the undead, automatons, and history’s greatest musician,” he says, referencing the likes of Sly Cooper, Sweet Tooth, Fat Princess, Sir Daniel Fortesque, Raiden, and PaRappa the Rapper. “That’s not… that’s not true, is it?” Kratos simply retorts: “I would not speak of this.”
