Mission 32 of 90Story mission
Elizabeta sends Niko to drive Playboy X to a meeting with a supplier, and the supplier is a biker called Johnny Klebitz whose own game runs this same scene from the other side. The deal is interrupted by a police raid nobody in the room expected.
The escape is the mission, and completing it opens Algonquin — the point where GTA IV's map roughly triples.
The meeting itself needs no fighting. Follow Playboy up and let it play out.
Two undercover agents start it and NOOSE come through the building behind them, two or three to a floor. The route out is up rather than back down the way Niko came — there is a combat shotgun on the first-floor staircase worth collecting on the way, and the stairwells are where the shotgun earns its place.
The top of the building crosses to the one next door, and the descent through that building is the same fight in reverse. An SMG suits the open roof better than the shotgun does.
There is a car parked at the bottom. Two stars have to be cleared before Playboy can be dropped at his apartment in the newly opened Algonquin.
Who this mission brings together, and the ground it covers.
