Juan Cortez

Cortez's final job: defend the colonel's yacht from a French navy ambush as he flees Vice City. Tommy mans the deck guns through wave after wave of attackers.
All Hands On Deck! is the final mission in Grand Theft Auto: Vice City given to protagonist Tommy Vercetti by retired army colonel Juan Cortez from his boat docked in Ocean Bay Marina in Ocean Beach, Vice City.
This mission can be played any time even after beating the main story.
The French secret service has discovered that Cortez sent the courier (in Mall Shootout) to steal the missile technology guidance chips, and now they want them back. Cortez, however, wants to keep them and so is escaping Vice City on his yacht. He asks Tommy for assistance. The boat leaves dock, with French secret servicemen firing from the docks and four boats following the yacht. Tommy fights them off and then more gunmen on Dinghies. The yacht reaches a bridge, which is blocked by more boats. More servicemen are also climbing on board, but Tommy again manages to defeat them. The French then attack with two Maverick helicopters and then a Hunter, with Tommy destroying all three. When in the open sea, Cortez asks Tommy to keep an eye on Mercedes and gives Tommy a speedboat to return to Vice City. Despite being told to keep the speedboat as a gift, there is no way to actually save the speedboat as there is no 'garage' for boats, but it will respawn where Cortez's yacht used to be.
