It's a HEAVILY CUSTOMIZED PC project from a die-hard BTTF and GTA fan. If you head to SeedyROM's YouTube page for this video, he instantly bursts our bubble: There is no single 'Download Link' for this mod. Thanks to Game Informer for the heads up. Modder SeedyROM went into the game and not only perfectly recreated the Delorean, he gave it the ability to travel back in time based on time circuits and the possession of plutonium. That's obviously not a plot from any kind of officially licensed Back to the Future story, just a possible reality in this insane custom modification of Grand Theft Auto IV for PC.
