Grand Theft Auto IV Walkthrough

Once up on the catwalks, you'll also notice that wave after wave of enemy continue to come along. They'll come from further up on the catwalks as well as in cars from below. The latter are extremely easy to take off, with or without explosives. With an RPG or grenades, you can launch explosives at them, killing those foes en masse before they're able to get out of the car. With an assault rifle, they're just as easy to kill as they get out of the car, unable to react. Eventually, you'll run into what seems to be the last of Bulgarin's foes. He'll drop the diamonds instead of handing them over (since he accurately describes death for him no matter which choice he makes). Once that happens, you can kill him and the rest of his friends before heading down a ladder. We're almost done.

Once down on ground level, you'll no doubt notice that you've attracted at least a two star wanted level. As a result, while you'll be in somewhat of a carless void, the cops that come after you will sacrifice their cars upon death (you just might up your wanted level a little bit as a result). So, grab a cop car (or any other vehicle in your vicinity). Once Packie jumps in the car, it's safe to head along the new route laid out for you on your HUD. Your destination is Packie's place in Dukes off of Savannah Avenue. Keep in mind that your wanted level might make this a rather tricky drive. The good news? Once you arrive at Packie's place, regardless of wanted level, the mission will end in success and your wanted level will magically disappear.
