This is the fourth installment of the gritty game known for its violence and flagrant disregard for the law. This time, players take control of Niko Bellic, a recent emigrant to Liberty City, who quickly gets embroiled in the danger-and the rewards-of a lethal life. Players can take a lot of liberties in Liberty City. There is a lot to see and do in town, and it's not for the faint of heart. It is available for Xbox 360 and PlayStation 3. Launch date:  April 29, 2008.
