According to this CVG report, Call of Duty: World at War Noah Heller has said that the game needs to change gamers’ perception of the entire WWII environment.
“Modern Warfare opened the door to so many people new to Call of Duty,” he said.
“The game built great fertile ground for us to start on and if we’re going to say: ‘Look it’s Christmas, here’s another Call of Duty as you loved it last year’, then we need to make sure the game is high quality or people won’t trust what Call of Duty is.”
Heller added, “This has to be the best shooter and has to redefine the World War II genre.”
