Woozie
Woozie sends CJ on a stealth swim out to a Da Nang freighter at night to plant a tracking bug on the Vietnamese gangsters' boat — without alerting the deck patrols.
Amphibious Assault is a mission in given to protagonist Carl Johnson by the Mountain Cloud Boys Triad boss Wu Zi Mu from his apartment in Chinatown, San Fierro, San Andreas. This mission can only be triggered between 20:00 and 6:00.
Carl meets Wu Zi Mu at his apartment in Chinatown. Woozie explains that he plans to plant a bug on a Da Nang Boys-owned ship in San Fierro Bay. Woozie asks Carl to do this, but Carl is reluctant to do so because of an experience he had (getting a condom stuck to his face) whilst swimming as a child. Woozie later admits to Carl that he cannot do it because he is blind. Carl, sympathizing with Woozie, has a change of heart and agrees to the task.
However, if the player's lung capacity is insufficient before starting the mission, a special cutscene will be triggered. While playing on the CJD 500, Woozie asks Carl if he can swim well, to which Carl replies negatively. The game would then tell the player to improve their lung capacity by diving underwater for the mission to be continued.
Carl makes his way to Esplanade North, near Pier 69. Once there, he dives into the water. He first navigates through a rock formation. Afterward, he sees and avoids the Da Nang Boys patrolling the ship and the sea in Tropics. He also avoids the search lights planted on the tanker. As he arrives at the freighter, he quietly makes his way to the back of the ship, either by avoiding the guards' attention or by killing them. He eventually arrives at the back of the ship, and plants the bug. After planting the bug, Carl leaves the ship quietly and swims back to the dock on Esplanade North.
