Grand Theft Auto IV Walkthrough

This chase, like so many others in the game, requires you to simply stay on your target. You don't have to try to run the target off the road (not that you'd be able to catch him anyway) or shoot at him. Holster your gun and concentrate on the road. This chase has an unusual amount of events that occur each time you play through, such as crashing vehicles spiraling out of control and incessant intersection congestion. Thankfully, this is a forgiving chase, so if you fall far behind, you can always catch up. That doesn't mean that you should fall too far behind, however, or an automatic mission failure is right around the corner.

Eventually, you'll find yourself on the west end of Algonquin, when the enemy's car loses control. They'll crash in a small park off of Castle Drive. When they do, Niko will tell Bernie to stay put. Get out of the car and head towards the two red dots on your HUD in the park. These dots represent the car's driver and passenger. Both are armed with pistols, but can be easily picked off with any weapon in your arsenal. Once they're slain, go back to the car where you left Bernie, get on in, and head back to Bernie's place on Union Drive West to conclude the mission.
