A reliable source has just confirmed the existence of Call of Duty 4. It will be developed by Infinity Ward, the developer behind CoD and CoD2. CoD4 is said to step away from the ruins of WWII and instead focusing on the battlefields of present day. The game’s realism is supposedly amazing, the source saying that you can shoot a soldier’s helmet on the side and make it spin on his head or you could shoot it right off. You might even be able to shoot soldiers’ ears off. CoD is said to be released for consoles and PCs also, but the release date is unknown.
