Go to Pier 400.
Follow the yellow route to the west docks of Port City . On the way, Trevor learns that Merryweather Security Consulting is active in the port, guarding a particular freighter, as well as boating in and out of the navy warehouse during some kind of mysterious offshore testing. When you reach the security gate entrance to Pier 400, drive on through as directed by the guard.
Park next to dispatch.
Follow the yellow blip and park. The supervisor has a slot on a cleanup crew at a waste spillage site. Floyd pushes poor Wade forward to take the slot.
Follow Floyd to the container handler.
Walk with Floyd (the blue radar blip) and listen to the conversation. He points out the Merryweather freighter and says it’s loaded with military containers that oddly aren’t being unloaded. As you get close, another supervisor points Floyd and Trevor to a container handler. Climb up the ladder on the side of the big vehicle. As Floyd notes, Trevor must do some actual work or else dock security will ask to see a Union card.
Move the marked containers to the loading area.
Check out the container handler controls shown in the upper-left corner of the screen. The two containers to be moved are marked as green blips on radar.
With the handler frame raised, drive the vehicle to Bay B and put its nose into the side of one of the marked ThriftEX containers. Lower the handler frame onto the container, then press the indicated control to latch onto it.
Raise the frame and follow the new yellow blip across the dock to the loading area. Lower the ThriftEX container onto one of the red slots in Bay F. Press the control indicated onscreen to release the container” Now repeat the process with the other marked container. As you do, Floyd points out a crane that might be a perfect perch for taking pictures.
Climb the crane to reach the cabin.
After Trevor dismounts from the container handler, follow the new yellow blip to the crane and start climbing the series of ladders to the top. Another boss orders him into the crane cab for some more work. Climb onto the walkway and walk toward the boss. Trevor automatically drops onto the cabin ladder. Move down to enter the cab.
Load the containers onto trucks.
Your goal is to use the crane to pick up a container and load it onto a truck trailer for transport. Use the controls shown at upper left to center the crane cabin directly over one of the two marked containers below (green radar blips).
Lower the crane onto the container and press the button shown to latch onto it. Lift the container high, then move the spreader backward past the other container stacks. The truck trailer is at the end of the stacks and a blue radar blip marks the spot you want to hit. After you get the first truck loaded, repeat the process with the second container.
Go to the vantage point at the end of the catwalk.
Climb up the short ladder from the cab and work your way to the spot (the yellow blip) at the end of the catwalk overlooking the Merryweather freighter, the SS Bulker.
Use the camera phone to take photos of the boat for Ron. Bring up your phone and select Snapmatic. First, photograph the front of the ship. Next, snap a photo of any guard onboard the ship. Then take a long shot of the back of the ship.
When you’re finished shooting, press the SEND PHOTOS button indicated onscreen and select Ron from your contacts list. Ron quickly acknowledges receipt of the photos.
Descend the crane to the docks floor
Climb down the crane ladders to the ground level, then find Floyd (the blue radar blip) at the semi-truck you just loaded. Hop into the driver’s seat.
Drive to the docking area
Follow the yellow route to the naval warehouse , in the south docks area. Reaching the yellow destination marker at the covered entrance triggers a cutscene: Trevor tries to bluff his way past a black-shirted Merryweather Security team and Floyd intervenes… which earns him a beating from the militia thugs. While their attention is on Floyd, Trevor slips into the security booth and snatches some documents in a briefcase.
Leave the restricted area and go to Floyd’s apartment.
Walk away from the checkpoint beating and commandeer the loaded dump truck. Then follow the yellow route back to Floyd’s apartment in Vespucci Beach. Climb upstairs to the apartment to trigger a cutscene: Poor Wade has returned from working the waste spillage crew. Trevor feels for him, but there’s work to be done. He clears a wall space and starts his heist planning board.
View Trevor’s planning board and select your approach.
Two different targets appear worth taking. First: a container likely below deck on the heavily guarded freighter. To get in, you must blow up the ship and grab the container underwater. Second: an unidentified item being tested off the coast. In both cases, you need a submarine for underwater pickup. For the second option, you also need a big cargo helicopter.
