Grand Theft Auto IV Walkthrough

Once you head into this room, you'll find Jimmy Pegorino. After blaming Niko for Kate's death (even though he was holding the gun—go figure), he'll run up the stairs he was standing on, towards the roof. Give him chase, heading up the stairs yourself. Once on the roof, be ready to immediately do battle with some of Pegorino's remaining soldiers, though you should be able to blast through them rather quickly. You'll see Pegorino head down a ladder, so give chase (you can just jump down instead of climbing). Run after him, taking out foes en route, including a pair of enemies that show up in a car as you near the pier.

Ultimately, Jimmy will jump into a speedboat and head off. On the dock, you will find a dirt bike. The game will encourage you (via a prompt) to get on the bike and speed along the coastal beaches in pursuit of Jimmy, so do so, going as fast as you comfortably can while keeping in mind that the sand is unsteady and difficult to stop on. Also, you'll run into some debris and people who, if hit, will force you to fall and almost certainly ensure your failure of the mission. This ride can be a bit of a pain, so take it easy, and if takes you a few tries, don't sweat it. Use it to learn the route so you know it better the next time around.

Eventually, as you ride along the beach, a helicopter will fly overhead. It's Little Jacob and Roman! The game will prompt you to use the ramp at the end of the beach to fly up to the helicopter. Hit it as fast as you can, but keep in mind you don't have to be going that fast for this to work. As soon as you've grabbed onto the helicopter, follow the on-screen prompt to pull Niko in. Then, ignore the instructions the game gives you. You don't have to remain too low—just follow the boat marked as a red dot on your HUD. It's heading for Happiness Island!

The helicopter will receive damage from an RPG, but Pegorino's boat is also already damaged. Both crafts eventually crash onto Happiness Island, and you will regain control of Niko thereafter. Chase after him (again, represented as a red dot on your HUD) and plow through his last few cohorts and you bum rush his position near the Statue of Happiness. Once you find him, begin shooting him, and the game will take over. We won't ruin the surprise for you here—just enjoy Jimmy's pain! Congratulations! You've beaten Grand Theft Auto IV. Here's hoping you made an alternate save so you can enjoy the other end route you could have taken.
