Payback (GTA IV)
Jimmy is pissed off at the way the Pavanos conducted themselves during the deal, and now he has revenge on his mind. Jimmy has learned that the Pavanos are due to make a cash pickup in Alderney soon, and he wants Niko to interrupt it and kill all the Pavanos.
Drive to the diner on Mueri Street in Acter, and stop in the yellow marker. Ensure you are facing north/east when you drive into the marker, because you're going to chase the Pavanos, and this is the direction that the chase begins. During the cutscene, the Pavanos recognize that you are representing the Pegorinos, so they attempt to lose you on the way to the meet. Chase the Pavanos through the various streets and alleyways, but don't shoot them, because you need them to lead you to the meet. Beware of the buses/vans/fences/scaffolding etc. which are designed specifically in this mission to disrupt your route.The chase ends at the AutoEroticar showroom in Leftwood. Use your vehicle as cover, and wipe out the Pavanos by launching grenades into the showroom, or alternatively use a rocket launcher. Lose your wanted level to complete the mission.
