The Mac version of Call of Duty 2 was released a few month ago. If you have already played it, you will probably agree that Call of Duty 2 is the best WWII game. Its action, graphics and everything are so excellent. Now, Treyarch and Activision are working on Call of Duty 3, whose Xbox 360 and PS3 versions are scheduled for release possibly by Christmas. Whether or not it’s coming to Macs, the game trailer below looks great and even better than Call of Duty 2.
