The Merryweather Heist (Freighter)
All 3 characters can follow the H sign that appears on Vespucci Beach. Trevor brings his cohorts, Wade and Floyd, with his partners Michael and Franklin. After Trevor detail the plan, Michael and Wade go off to get the wetsuits required for planting the bombs. Trevor and Franklin head downstairs to the car.
You control Trevor, go downstairs and get in the car with Franklin and drive to La Puerta Freeway bridge which overlooks the port of Los Santos. The destination marker is the yellow divider lines in the center of the freeway. When you get there, Trevor gives Franklin a thermal scope for the Sniper Rifle. Guide Franklin to the designation point as Trevor drives off.
User the thermal scope to start picking off the Merryweather guards one by one, going for the headshot (12 are required to 100% the mission), being extra vigilant for targets lined up to take two out with a single shot. When the first two guards are down, Michael will board the boat.
You can switch to Michael to plant the bombs and freely switch between Michael and Franklin to eliminate the guards. "Critical Locations" are marked with yellow dots on the map where the bombs need to be planted. When Michael reaches these critical locations, open the weapon wheel, select the Sticky Bomb, and plant it on the structure with the "Caution" sign on it located in front of Michael. (an on screen prompt will tell you when to plant the bomb)
Work your way down toward the last yellow dot on the map. Switch to Franklin and use the thermal scope to locate any additional targets. Once clear, switch back to Michael to plant the bomb.
Noe sneak down to the ships left side and find the staircase leading up. Climb the stairs to find the hatch that automatically opens and plant the last bomb inside. Now you automatically switch back to Franklin. Carloads of Merryweather guards arrive and fan out around the dock, they spot Franklin on the bridge and start firing at him so be sure to take them out quickly. Also be cautious as a Merryweather Helicopter also targets Franklin so try to snipe the pilot as quickly as possible. When the dock is clear, Michael appears from the hatch.
More guards deploy across the boat, so help Michael via the use of Franklin of switch to Michael if a target is blocked. Keep doing this until Michael finally reaches the far side of the boat and dives into the water to escape.
Switch to Michael who needs to locate the crate. Swim underwater and in through the debris and listen for a sonar ping. The closer you get to it, the faster it will ping. The device can be found on the ocean floor; when you get close enough it will appear as a green dot on the map. Swim down and trigger another character switch, this time to Trevor in the sub.
User the radar blip to guide Trevor to Michaels location. When you reach the crate, guide the submersible directly over it to pick it up. Follow the new yellow dot that appears on the map where Floyd is ready with his crane. Once you reach the dot, be sure to hit the underwater ring marker to trigger a cut scene in which the sub is lifted out of the water.
Lester suddenly shows up with some unsettling news and takes the prize himself to hide it. As Lester drives off, the mission ends.
