Behind the Design is a special Bonus Round where we go straight to the developer to talk about their design philosophies, receive their commentary on the trailers they've created, learn about what has hit the cutting room floor and more! What challenges does Treyarch face creating a new Call of Duty? How different is it to work with fictional history rather than World War II? What's this about a Black Market feature in multiplayer that was cut? You asked for us to go behind-the-scenes - and now, we're Behind the Design!
