Move with your team and go through the door to Graves' right. There are two enemies behind the door right in front of you, the one that leads to a red room, so be careful. Clearing the Rig Exit the red room and keep moving. Go up the stairs with the rest of the team and neutralize any enemies you encounter. Keep moving with the team and clearing areas until you guys get to where the blue container is. Investigate it only to see it is empty, so the controls to the missile must be on the ship. Boarding the Ship Move right and use the rope to get down to a boat that will take you guys to the main ship. Once you board the main boat, you will need to clear the area. The problem is that the tides are strong, and the containers on the deck wobble with the ship. Avoid getting crushed by the containers while cleaning the area from enemies and pushing forward. A good tip is to use the red structures to the sides of the boat to crouch and deal with enemies from there, as these structures will keep you safe from the containers.
