Flatline

In this mission for Jimmy Pegorino, you'll find out that Anthony Corrado, Pegorino's best guard, was wearing a wire and working for the government. He needs you to silence Corrado. Get a car and drive to the hospital. Park your car at the curb and exit it. Don't enter the hospital with a weapon drawn or you will get police attention!

When you enter the hospital, make a right and another right to the changeroom. In one of the lockers you'll see a doctor's outfit. Walk into it to put it on. Now go back and make a right. Then make a left and go to the end of the halls. Get into Anthony's room. The bodyguard will walk out. To let Corrado know that you're Niko, go to the side of the bed where Anthony's head is facing. Otherwise, he'll think you're Pegorino.

There are two ways to end Corrado's life. If you want to execute him, point a pistol at his head and shoot him. This will draw more attention than the following method. Alternatively, you can face the life support machine and deactivate it. Niko will say a one liner and begin to walk out. Continue to WALK down the hallway (do not run or sprint, you will attract attention) until you are in the waiting room. Once you are there, you will receive a 2 star wanted level. Outrun it and complete the mission.
