At the beginning of the mission turn to your right and run towards the awesome green Honda Civic. Watch out for Yardies on the streets and coppers. Here's the directions to get tot he next destination:

Once you're in the car:

Drive around the copper

Take a right at the end of this road

Mind the cop

On this road, also watch out for the wankers in the Yardie cars

At the end of the road, turn left

Keep going until the road ends

On the way, you will probably have to dodge the oncoming Yardie car

Take a left next to the building in front of you

After all the pylons, stay left and go around the roundabout to the other side and keep going straight

Turn right and go around the bend

Take the first left and stay left

Turn right

Go through two intersections

Drive off the ramp to the right of the coppers' roadblock

Stay right and continue going right

Keep going until the road becomes a big intersection

Take a right down the main road

Go through two lights then stay left when the road divides

Go straight through the roundabout and through one of the 3 arches in the big archway straight ahead and drive down this large pink road

When you reach the front of Buckingham Palace,(the next big intersection) turn right and go down yet another large pink road

If you don't want to dodge cars, then drive in the dirt path to the right

At the roundabout, turn left, then left again

The van is just down this road on the right side

Don't worry about killing enemies that followed you this far, just get in that van!

===== VIDEO =====

Mark has to go find the real van and kill the driver. Here are the directions to find him: When you start, pull a 180 degree turn and go down the road

Turn left

Turn left again

Take the next left, you're now in front of Buckingham Palace again

Go the opposite way that the Palace is facing, which is the same road you came from earlier

At the roundabout, go straight through it to the other side

Turn left at the next lights

Don't take the immediate right, but take the far right

Stay right after the turn

Take the next left AFTER the road divides

Take a right

Go left around the pink building

Turn left onto the main road, then turn right immediately after that

Go through the small intersection

Stay left at the fenced-off area

Take the next left, then left again

The other van is on the side of the road to the right coming up

When you see him, drive head on into the sucker

He'll take off down the road the other way

Keep smashing his van until he gets out

Kill him for fun if you want, because all you need to do is make sure he isn't the one who shows up to fix the phone lines at the Police Station;your next destination - You don't have a gun, so you'll have to break his neck

Keep going down this road until your left blinker flashes very fast

Take the left onto the Police Station road

Stop by the door, which is on the right, and go inside.

Once in the Police Station, a guard will be standing there, waiting for you. He will guide you to a room, so follow him. If you know where the room is, run there yourself because its a lot faster. Wait in the room until he leaves then exit the room, turn right, then go down the right hallway and left down the next to find the stairs on the right. Go up them and cut through the "Intel Office", which is the first doorway on the right, to the next hallway over. Then turn left and enter the "Evidence Room," which is the only other door open in this hallway. Grab the Pistol on the floor and holster it. Now walk outside the room and go against the wall in front of you, strafe right and you should see McCormack with a fellow Officer. If you strafe to the end of the wall, McCormack and his buddy will turn around and walk the other way.

Note that it is impossible to kill McCormack at this point in time no matter how many times you shoot/pistol whip him. However, you can damage him to a degree that he limps and walks slow. So, for now just kill the rest of the police officers. There are a few strategies once you get the gun. You can use stealth and break a few necks, you can shoot up anything that moves or you can just chase McCormack and only kill the Cops near him and heal a lot. If you choose to shoot, you better auto-aim around every corner and heal every time you get a chance. You only need to kill McCormack to beat the mission, so I'll describe how to follow and finally kill him...

After McCormack and the other cop near him turn around and walk down the hall, follow them but don't go to close and look around corners before going around them. After they turn left around the corner, put your back up to the wall and you'll see McCormack and the other Cop are now split up. Follow McCormack into the room on the left at the end of the hall. You'll see a Cop with his side to you. Quickly turn left in the room and walk to the wall. Turn right and then look towards where the Cop was. Go up behind him and break his neck. Go out the door to the left now. Make sure your gun is still holstered. McCormack cuts through the room in front of you, but don't follow him. Instead, follow the hallway to the left and put your back up against the wall. You'll see McCormack walk out of the door and down the stairs you came up. Follow him down the stairs and into the room where he turns around and take out you Pistol(s) and start shooting him while running into the room and try to whack him once or twice and he will fall to the ground. Since you've defeated McCormack there is a video.

Now you will have to escape with Yasmin. A guard will come up to the door, kill him and continue down the hallway and kill the guard at the end. Go further down the hallway and take out the guard behind the wall and another guard will run around the corner and will try to run into the open room nearby, kill him before he does and continue running down the hallway, turning left and you will see a smoke grenade fly through the air and smoke will come out. Run to where it came from and use the auto-aim to take out the 3 SWAT guards through the smoke, because they can't see you. Continue down the hallway where you haven't been yet and go right and you will see another smoke grenade fly and start to smoke. Let the SWAT guards come up past the smoke so you can see them and take them out. Get one of their MP5's and follow the hallway where they were. If there are any more guards in the area, take them out. When you can, go left and find the door to outside and look at the closing door moving. Try to shoot the "Yellow Box" that Yasmin refers to and the door will stop closing. Find a car in the parking lot and exit the area. If you don't make the moving door stop, don't worry, there is an alternate exit. Find the other open door outside and there should be an exit there.

If you break the control box, then go out the door. If not, go to the main entrance, which is now open for you. From here, turn right, out the door, and right at the next road. Get a car. Here are the directions to get to the next destination from the back gate, which is where you should be:

From the back gate, go under the tunnel straight ahead

Turn left, then right at the intersection

Keep going until the road ends

Drive straight into the warehouse parking lot.
