Grand Theft Auto IV is actually the sixth title in the Grand Theft Auto series of games to make it to the PC. In it players take on the role of Nikolai "Niko" Bellic who has come to Liberty City to start a new life. Soon after arriving Niko must fend for himself and turns to a life of crime. Like other titles in the series the story lineis based on your ability to complete assigned missions, with a number of side missions that help you gain experience and items that can help in the objective based mission. Grand Theft Auto IV however is planned to blend these missions and make them a bit more open ended with player actions determining the flow and outcome of the game.
Although to date there has not been an official announcement for the PC release, if the previous titles are any indication it should be out within six months after then PS3 and Xbox 360 release in April 2008.
