Many players reach a point in Grand Theft Auto San Andreas where progress seems blocked, and one mission in particular causes confusion Amphibious Assault. This mission is part of the storyline involving Woozie and the Triads, and it cannot be started immediately like most other missions. Understanding how to start Amphibious Assault in GTA SA requires patience, preparation, and awareness of specific in-game conditions. For new and returning players alike, this mission often feels hidden, but once the requirements are met, it becomes a memorable and challenging experience.
Understanding Amphibious Assault in GTA San Andreas
Amphibious Assault is a mission given by Wu Zi Mu, also known as Woozie, in San Fierro. Unlike many missions that simply appear as markers on the map, this one is locked behind a skill requirement.
The mission focuses heavily on swimming and underwater movement, which is why Rockstar Games designed it to test the player’s swimming ability.
Why the Mission Is Different
Most GTA SA missions only require story progression. Amphibious Assault is unique because it also checks CJ’s physical stats before unlocking.
This design encourages players to explore side activities instead of rushing the main storyline.
Basic Requirements to Start Amphibious Assault

Mandatory Conditions
- Completion of previous Woozie missions
- Swimming skill at 20 percent or higher
- Access to San Fierro
The most common reason players cannot start the mission is low swimming skill.
Checking Your Swimming Skill
