Activision has been lip-tight about any multiplayer information about Modern Warfare 3 so far. They probably want to keep few info for the surprise or they are just playing it tactically.
Either way now and then we hear something cool about Modern Warfare 3 from Robert Bowling of Infinity Ward. Who recently revealed some of the new aspects of game’s multiplayer. He told that players will be able to play multiplayer modes in Modern Warfare 3 offline/split screen without any internet connection.
He has also hinted in one of his interviews that the unlock system for Modern Warfare 3 will be quite different from the traditional system. What is that? We don’t have any details on it yet.
We will have to wait till September 3rd when the details about the multiplayer mode of the game are expected to be revealed officially.
