Mission walkthrough
-
Prepare CJ for the swim
If Woozie refuses the job because CJ cannot swim well enough, practise diving in safe water and resurface before the breath meter empties. Return to the mission marker between 20:00 and 06:00 once the requirement is met.
-
Use the underwater passage
Go to the docks and follow the marked swimming route. Dive through the tunnel, then surface in the safe area to refill the breath meter before the next exposed stretch.
-
Avoid the patrol boats
Swim underwater when passing their lines of sight. If spotted, dive to break attention, but watch your remaining air. Choose a safe moment to surface instead of staying submerged until CJ begins losing health.
-
Board and plant the bug
Use the tanker’s access point, then move quietly along the deck. Deal with guards from behind when needed and reach the marked planting location. Press the indicated interaction control.
-
Return to the docks
Leave the ship after confirmation and swim back using the same careful approach around patrols. The return marker finishes the job.
Key point
Swim training is a prerequisite, not an optional performance bonus. If the opening conversation blocks the mission, raising lung capacity is the solution rather than repeatedly entering the marker.
