When you start the Vice City Stories game you will firstly be confined to one area and if you're wondering how you can move on to another location, you should keep in mind that all the missions in the story mode need to be completed. However, there is one particular mission that will unlock Vice City Beach. When you turn on the game you'll realise that you don't have access to Vice City Beach because there is a threat of a hurricane. During this time you should complete the missions given to you by Lance Vance and Bryan Forbes. Lance Vance will give you the mission 'From Zero to Hero' and to complete this successfully you will have to get revenge on Jerry Martinez by killing the drug dealers getting cocaine for Martinez. When you go to the dockyard you need to make sure Lance is protected, and once you've killed the crew, Martinez will arrive.
Then you need to jump into one of the trucks and follow Lance. He'll take you to a bridge where you'll have to travel to the end trying to avoid rocket attacks from Martinez. Once you get to the end of the bridge, the cops will chase Martinez but then start coming after you. When the cops start chasing you, you need to make sure you follow Lance to a safe house. When you get inside Lance will pay you $3000 and a new safe house will be unlocked. You'll also be able to buy two new items and unlock Vice City Beach.
