Grand Theft Auto IV Walkthrough

Meet up with Derrick back where you first met him, in the small, trashy park in Alderney near Hardtack Avenue. When you arrive, he'll be freaking out. Clearly, this guy drinks too much and takes a wide variety of drugs that are forcing him to tweak. But, within all the madness, Derrick has yet another assignment for Niko. Niko seems to have some sort of soft spot in his heart for guys like Derrick, and he agrees to undertake the endeavor. This is a dangerous mission, though, since you'll have to "fake spring" a guy from jail by attacking his escort caravan.

Right after taking on this mission, you'll receive a call from Derrick's brother, Packie. Packie will tell you he heard of your mission, and that it's a tough one. So, he's left you a truck near the center of Alderney in an alleyway off of Jonestown Avenue. Inside the truck, you will find a rocket launcher, and as Packie tells you, it will also be used to seal off a road (he'll seal off the other end of the road). Your target has an incredibly huge police escort, and you're going to need the help. So, first thing's first -- head over to the alleyway (your GPS will take you there easily enough) and grab the truck.
