Grand Theft Auto IV/Roman

Niko's cousin Roman has lived in Liberty City for the last fifteen years, and is your first point of contact in the city.

The Cousins Bellic
Your exuberant cousin has had a little too much to drink to celebrate your imminent arrival in Liberty City, and decides it would be better if Niko took the wheel for the trip home.
 * Starts: Automatically

Follow the yellow GPS line on your mini-map to Roman's less-than-impressive apartment. Niko is understandably disappointed by the harsh reality after Roman's optimistic email descriptions of his standard of living, but Roman's got to take the car back to the cab depot. He gives Niko directions to the depot as he rushes out the door.

It's Your Call
Get into the cab and follow your GPS to the hardware store on ?? St. Park the car in the marked area and Roman will get out, and hands you a cellphone. He's expecting some Albanian loan sharks to show up looking for him, and wants you to call when they appear.
 * Starts: Bellic Enterprises Cab Depot

Roman will phone you after a few minutes of your lookout duty, and a few minutes more after that the Albanians will appear. Pull up your cellphone and call Roman; he'll run out of the hardware store's back door and jump into the car beside you.

From here, you've got to lose the loan sharks; take a few corners and they should be taken care of. Once they're off your tail, drive Roman back to the cab depot to complete the mission.

Three's A Crowd
Get in Roman's Cab, and drive to to the subway station where Mallorie and Michelle are waiting. Take the girls to Michelle's house in Rotterdam Hill.
 * Starts: Bellic Enterprises Cab Depot

Once you've dropped them off, Niko will call Roman and talk about the experience; Roman will direct you to a clothing store near his apartment. Go there and buy a new outfit - this first time is free - and you'll get Michelle's phone number, which unlocks the dating sub-game.

Uncle Vlad
You must have completed all of Vlad's missions to unlock this mission.

Roman's Sorrow
Go to the alleyway Roman is hiding in. Then drive to the apartment and then the depot. Then go to Mallories' cousins apartment.
 * Starts: Answer the phone call from Roman.
