Grand Theft Auto: Vice City

Story related, cannot be missed.

"All Hands on Deck!" is the final mission given to you by Colonel Juan Cortez. In this mission you will need to fight off the French Secret Service as Cortez leaves Vice City aboard his yacht. As the yacht travels through the water you will need to shoot pursuing boats and helicopters as well as as clearing barricades of boats. It's best to have armour and a heavy machine gun for this mission or even better, a Rocket Launcher. If the boats get close then the men will board the ship and make their way to the top where you are located so be sure to watch out for them. At the end of the mission you will need to destroy a Hunter helicopter. Once it is destroyed, a cutscene will begin and the mission will be completed then the trophy will unlock.
