One of the most exciting and innovative features in the multiplayer modes is that groups of players will be able function cooperatively as a team and serve different roles, as seen in this trio of soldiers on a jeep. One player can be the driver, another riding "shotgun" will be able to lend fire support while the final passenger will be able to act as the main gunner. Not only has vehicular combat been rarely done as effectively in a game, but the degree of complexity which Bungie is striving for is simply unprecedented.
