Mob bosses need favors, crooked cops need help, the street gangs want you dead; so to compensate you'll have to rob, steal, and kill in order to stay alive, while using your resources to track down the woman who betrayed you and earn your rightful revenge. But that's all in a day's work in Rockstar Games' Grand Theft Auto III. GTA3 is the first installment of the series to utilize a fully three-dimensional living city with open environments and non-linear gameplay.
