Grand Theft Auto IV Walkthrough

You'll also want to keep an eye out for enemies on the catwalks and in the offices above on the second floor. From there, they will be able to take great shots at you that will avoid almost all available cover. So, keep an eye on both sides and make those foes a priority. The red dots on your HUD represent remaining enemies, and as you plow through them, their numbers will steadily decline (be sure to grab any dropped weaponry or money dead foes leave behind). When all foes but Dimitri and Niko's old friend are killed, those two will make a run for it, leaving you to deal with the police that just arrived on-scene.

Because the numerous Russian mobsters trapped you in this warehouse, backtracking the way you came isn't an option. The garage door you came in through is now shut. This will force you to plow through the three or four squad cars and six or eight cops waiting outside for you. Try to nullify who you can while still inside the garage, and then use the nearest cop car for cover as you head outside. Steal one of the cop cars the first chance you get, and then drive anywhere on the borough in order to lose the cops. Once you have, you can then bring Little Jacob back to Homebrew Café, as requested.
