Harboring a Grudge/Walkthrough
The following is a walkthrough of the mission Harboring a Grudge in Grand Theft Auto IV.
Drive Packie to the docks. Once you arrive, follow Packie. He'll run around to the back of a harbour warehouse overlooking the Triad deal. The game will introduce you to climbing and shimmying as you and Packie scale the warehouse to access the roof. When you reach the top, and a cutscene will start, showing a boat pull up with the meds, which starts to get loaded into a Yankee truck. Packie will then instruct Niko to climb down the small mini-cabin on the side of the building next to the river and start shooting the Triads. Climb down, and slowly sneak behind the large warehouse boxes. Start firing on the Triads and Packie will give you support from the roof. Packie will draw some of their attention, but they will still shoot at you. When everyone outside has been killed (including the guy on the boat), The thugs inside the warehouse with the truck will start shooting, too. Be careful not to destroy the truck. After everyone is dead, enter the truck with the meds and wait for Packie.
Packie will follow Niko into the truck, and instruct Niko to drive the truck to a lockup in Westminster. Start driving to the lockup, but some Triads in cars will start following and shooting you. Niko will find some grenades in the truck, and you can drop them out the window to blow up the cars (Be careful; the truck is slow and it might not clear the blast radius if you "cook" the grenade too long). No matter what you do, get to the lockup. Niko will park the truck in the lockup and the pair will exit the truck. Ray will pull up and pick up Packie to talk. He will also take Niko's number for more work.
Hints
- In the warehouse with the truck there is a first aid kit in the office. Niko can also leave the gunfight to restore his health at a food stand.
- If you have access to Dwayne's backup, you can summon it before leaving the rooftop. The extra gunmen may not immediately arrive and may be "hung-up" getting through a fence though they may still fire on enemy from a distance.
