The next installment in the popular Grand Theft Auto video game series comes out on April 29th, 2008. This fourth edition of the controversial crime game deals with a Russian mobster running amok in Liberty City, a fictional stand-in for New York. Photos of a Liberty City map were leaked on Kotaku this morning and to help whet your appetite for spreading murder and mayhem through this virtual cityscape, I've mapped some GTA IV locations onto their New York inspirations.
