Call of Duty 2 is the latest in a very successful series that was designed to recreate the famous battles of the Second World War down to the smallest and goriest details. This endeavor was so successful that Call of Duty now has one of the largest communities (for a single-player oriented gameplay) and there are a lot of plans for a future game on any imaginable console.
