The much awaited trailer of Activision’s Call of Duty 4 was released recently . Unlike the previous COD games which were based on World War combat , this one is based on the new modern combat featuring terrorists and nuclear weapons (hopefully) . So this one is going to be a game to watch out for . Pity COD 3 was not released for the PC but lets wait for this game eagerly . Lets hope we get this on PC .
