the series, assassin�*s creed: valhalla, transports the action to the ninth century as vikings attempt to settle in britain, something that doesn�*t go down that well with the locals. valhalla�*s developers have worked really closely with historians and archaeologists to ensure historical accuracy and real locations like this one, portchester castle on england�*s south coast, appear in the game. we tried to research the kind of people we would meet there but also their habit, the way they would talk, the way they would live their daily lives.
