One of the many interesting wrinkles in GTA's gameplay is that the game now has a two-player cooperative mode. Now, before you get too excited about this, you should know that you can't actually play the entire game with a friend. Instead, you'll run into little two-player icons in certain spots in the gameworld. Walking over one with a second controller plugged in lets you start up a series of special objectives that work sort of like the rampage icons in previous GTA games. You and a friend will be able to wreak havoc in a car or on foot, though the game requires that both players remain on the same screen. While the concept of a multiplayer mode in GTA is pretty mind-blowing, the implementation here makes it more of a fun little addition that, along with all the other crazy things you'll come across as you play, contributes to the feel that the game has a million different things for you to uncover. OK, while there aren't quite a million side missions in the game, it seems to come pretty close, offering everything from a basketball minigame, to pool games played for money, to arcade machines that pay homage to classic games like Gyruss and Gradius.
