When you take control, you have to drive. Here are the directions to get to the next destination:

Go out the gate to the left of you

Turn right

Keep going till you can turn right again

Turn left at the roundabout

Keep going till you have to turn

Turn left then right

Go over the pavement and under the tunnel

Go left then right onto the bridge

It's packed with cars so don't drive crazy here

Turn left when you can

Turn left into the now open gate

Stay left and keep going till you see a small gate on your right

Get out of the car and go through the gate

There's 4 Yardies talking just inside the gate. Run in and cap them all. Be aware that there are other Yardies up on crates around this area, including one right beside you up on the crates, so be careful especially when you choose a spot to heal. Back up a bit so you can see him then kill him but you can't get his AK. You might encounter a few guys who seem to come out of nowhere, so be warned. In this storage yard, there are cranes driving back and forth that you must avoid while navigating this area. If you get run down, you'll start from the gate. Take the first small passage on you left after you turned right when you killed the 4 Yardies at the gate. Turn left again and run to the back crates in the open area. Go around the crates to the far side and go down the far left passageway. Turn left, then run through the next 2 passageways in front of you. Turn right, go through the passageway on your left, turn left, go through the passageway on your right. Turn right and run to the end of this passageway. Kill the 2 guys who are up on crates. At the giant spools, turn left. Run around the corner and if you see anyone, blast them. There are more Yardies around this area, but depending on how fast you got here, they might be right around the corner or farther away on their patrols. Heal now if you need to. Go around this area hunting down anything that moves, making your way to the other side. When you see trailers and some white vans, head towards them. The vans drive away when you enter the parking lot. Use auto-aim to blast any Yardies that put up a fight. Now you get SWAT backup once again. Make your way to the vans which only drove behind the trailers on the other side of the parking lot. If any of the SWAT guys die, steal their MP5's! Blast the last few Yardies around the vans then Frank tells them to get "Out'ta the car!". Mission Complete!
