Portland: Get to Staunton Island early
Use the following trick to get to Staunton Island before the bridge is fixed and before the subway is open. Go to the bridge to Staunton Island. Go past where the blockage cones are located, to basically be on the bridge. Enable the "Flying car" code, then the "Tank" code. Make sure you are all the way back to get enough room to take off using the tank (as a plane). Start firing the cannon backwards and accelerate. Keep firing the cannon backwards, and just as you get to the edge where the bridge has been broken, you will take off. Try and get back on the ground. If done correctly you will now be on Staunton Island. Note: When you cross the bridge, the "Welcome To Staunton Island" screen will appear to confirm success. Note: You can use nearly any car, but the tank has a better ability to fly higher.
Steal an Ambulance from Sweeney Hospital. Go to the bridge and enable the "Better driving skills" code. Drive your ambulance on the road towards the bridge and press L3 just before the road starts to dip down. If done correctly, you should make it across, but your ambulance will probably tip over and explode. Make sure you are out of the way, then run into Staunton Island.
Note: When on Staunton Island you can not do any missions. When you die, you will be transported back to the hospital in Portland.
You can fly over to Staunton Island by enabling the "Tank" and "Flying car" codes after dropping off 8 Ball. However, only activate the "Tank" code when you have walked onto the broken bridge. You cannot save the game over in Staunton Island, and if you die or get arrested you will be transported back to Portland.
Enable the "Better driving skills" and the "Flying car" code after you drop 8-Ball off at the hideout. After you drop off Misty at the Luigis Sex Club Seven, go to the fire station and get the fire truck. Do not disable the codes. Instead, go to the bridge and jump the gates. Drive off the bridge slowly until there is a big shadow mark, then hit the gas. Once you start going in the air press the Up for about one second, then release. Keep doing this continuously. Once in Staunton Island you can easily go to the lift bridge to go to Shoreside Vale, however the lift bridge is more difficult than the Callahan Bridge.
Steal a Mafia Sentinel and go the Callahan Bridge. Aim the Sentinel towards the break in the bridge and floor it. The car will leap over the gap in the bridge.
Get a Banshee (one location is in the glass-windowed building next to 8-Ball's Bomb Shop) and go to the bridge that leads over to Staunton Island. Get on the edge of where the bridge starts, and drive up past the obstacles. Enable the "Flying car" code. Drive fast to get across the opening; start near the bottom of where the bridge starts. When you approach the opening, press Up to fly. Note: This must be timed correctly,
In the "Last Request" mission, it is possible to "maroon" the Japanese girl. To do this, look for the closest "Island" when you pick her and Maria up. Get to the island and back the boat up a slope. You will hear crunching sounds. Experiment, and sooner or later she will drop off the boat and onto the island. From there, get to Staunton Island. You can cruise around and do everything else except take up any missions or side jobs. Kill Maria or the Japanese girl and the mission will end.
