There's no denying it: this is the real deal. A leaked video of the PS3 version of Grand Theft Auto IV's intro has been making its way across the web. However, this is the only one that includes (shock!) in-game footage and gameplay. Rockstar is actively trying to shut all of these videos down, so we hope you'll be able to see this by the time you get to it.
Update: Looks like Rockstar's ninjas have finally killed this video. If we find another host, we'll put it up. Until then, enjoy some direct-feed gameplay, after the cut (while it lasts!).Update 2: Watch someone play the game live here.
