Here's a little background information on the upcoming game:
Grand Theft Auto V follows the lives of 3 very different criminals who plot their chances of survival and success: Franklin, a street hustler looking for real opportunities and serious money; Michael, a professional ex-con whose retirement is a lot less rosy than he hoped it would be; and Trevor, a violent maniac driven by the chance of a cheap high and the next big score. Running out of options, the crew risks everything in a series of daring and dangerous heists that could set them up for life.
The biggest, most dynamic and most diverse open world ever created, Grand Theft Auto V blends storytelling and gameplay in new ways as players repeatedly jump in and out of the lives of the game’s three lead characters, playing all sides of the game’s interwoven story.
