Blow Your Cover/Walkthrough

The following is a walkthrough for the mission Blow Your Cover in Grand Theft Auto IV.

Elizabeta Torres asks Niko to go with Playboy and Johnny to watch over a drug deal. A helicopter or a taxi would be really useful because it's a long ride, but take any vehicle that can fit Playboy and drive him to the building in Broker. His yellow Patriot should be parked outside.

Collect the shotgun under the stairs, follow Playboy X up to the third floor, and walk up to Johnny. A cutscene will follow. Johnny, Playboy X and Niko go into a room where two undercover LCPD officers are. One of them asks over and over again, "Are you carrying the stuff?" Then suddenly, as Johnny tries to call the deal off, the two undercover LCPD officers surround Niko and Playboy with guns, yelling "Freeze motherfuckers". Johnny takes out the ambushing NOOSE team, and goes down stairs to fight the cops head on, and escape.

Shoot the officers on the remaining floor and go back to the stairs. Behind it are two FIB officers, kill them. Keep going up the stairs with Playboy following you and shoot every FIB officer standing. When you get to the roof, gain cover and kill the remaining FIB men. Two of them walk up the fire escape. Shoot them down the stairs; they came to the "party" late.

Follow Playboy down the fire escape and kill the remaining cops on the stairs. Use a nearby door to go down to street level. When you're down there, lose your wanted level and drive X to his penthouse in Algonquin (Algonquin is unlocked once you get to street level with Playboy).
