There's a nice little Q&A session available over on Total Videogames , the chat is with Infinity Ward`s CCO about the forthcoming Call of Duty sequel.

WW2 is a popular theme throughout videogames, however the original Call of Duty managed to rise up amongst the deluge of competition and rightfully took its place at the top; so when it came to developing a sequel what were some of the main issues and design objectives in regards to the predecessor have been undertaken during the development of CoD2?

Call of Duty 2 goes beyond the first game with a brand new graphics engine, non-linear storylines and open gameplay with multiple objectives and paths per level. The AI is much more advanced, integrated with our Battle Chatter system that delivers the experience of World War II combat as never seen before in a game. Also, there are more levels than in the original, and they are larger with multiple paths and objectives.
