Grand Theft Auto 4 Guide - Elizabeta's Missions (Bohan)
Mallorie will call you shortly after the completion of “Street Sweeper” in Manny's mission line to tell you of a friend of hers who needs some work done. Hit the marker outside of Elizabeta's place—denoted by the ‘E' symbol on the radar—to get a mission from her.
Mission 1: Luck of the Irish
Get to the building that's marked on your radar and step inside. Climb the stairs all the way up to the rooftop and pick up the Sniper Rifle there. Step over the vantage point to observe the meeting. Pay attention to the instructions that appear in the top-left corner of the screen to learn how to use this weapon. The meeting quickly goes sour as the dealers pull guns out and start firing at Packie and his associate.
Immediately start sniping the attackers below. Try for headshots, as it'll take a couple of flesh shots to down one. Keep watch over Packie too, because at one point an attacker will grab hold of him and attempt to stab him. You'll know this is happening when a marker on your radar is flashing red and blue. Afterwards, kill the second batch of attackers that enter the alleyway to complete the mission.
Mission 2: Blow Your Cover
The contact's apartment is in Schottler, which is back in Broker. Drive over there with Playboy and enter. Upon entering, grab the rifle that's leaning against the window up ahead before following Playboy up to the 3rd floor to make the deal. It's a setup. Gun down the two cops in the initial area, then crouch down and head into the hallway. You have to get up to the rooftop, but there are four SMG-wielding cops between here and there. Move carefully as you make your way up to the roof, because the cops are quick to react and are wearing Body Armor, making them considerably harder to take down.
When you reach the rooftop, grab the health pack behind the nearby cover and start firing at the cops up ahead. Be sure to pick up the Body Armor that is near one of the generators just before the rusty set of stairs. Your deeds will net you a two-star wanted level, and you now have to get Playboy back to his place in Northwood. Follow Playboy down the stairs; there are a couple of unmarked cops on the way down, so proceed with caution. Once you're outside, lose the wanted level and then drive Playboy home to complete the mission.
Mission 3: The Snow Storm
You should get a call from Elizabeta sometime after completing “The Puerto Rican Connection” in Manny's mission line. You first must travel to the old hospital all the way on Colony Island. It's quite a long way, so take a cab if you aren't feeling up to the journey. When you reach the place, hit the marker in the parking lot to get started. Approach the place, but be careful, as the old hospital is crawling with enemies. Start by gunning down the two guys in the fenced in area outside, then head through the gap in the fence.
There is a ladder along the hospital's south wall that can be used to reach the second floor, which would provide a nice vantage point. There are a couple of guys up here as well, so quickly take them out before they can get a shot off. You can use the explosive barrels against the enemies down below by shooting them; just don't set one off too close to yourself.
Once the ground floor is clear, drop down to the left and head through the northward doorway. Turn into the first room on your left to find the coke that Elizabeta is after. There is also Body Armor here, so be sure to pick it up for extra protection. Unfortunately, the cops show up to raid the place just as you are about to make your escape. Here's the escape route: exit the coke room and turn left, sprint through the doors until you are at the second to last one, then turn into the room to your right; here, go through the doorway on the left and then exit through the arched doorway. Of course, you'll have to fight your way out, and the sheer number officers standing in your path makes this a decidedly difficult task.
Be especially careful of the two cops stationed outside; try to gun them down through the windows before heading outside. When you've made it out of the hospital, quickly get a vehicle and start flee the scene. You now likely have a three-star wanted level to shake. A good way to escape is to set a way point somewhere far (South Bohan, in this case) and follow the marked path on your radar. Doing this ensures that you won't be caught circling around the same area. Once you have lost them, meet Jacob in Chase Point to complete the mission.
Mission 4: Have A Heart
Get in the car outside and start towards the doctor's location in Broker. Drive carefully, because a collision may jar the car's trunk open, revealing the contents to any passersby; including the police. If the trunk does open, however, you can always step out of your car and shut it. Hit the marker in East Island City to trigger a cutscene and complete the mission.
