How To Get To Stauton Island Before getting all the mafia missions

ok, in order to get to stauton island before completing the mafia missions, you must turn on the dodo cheat. Once you have the dodo cheat on, get a pretty fast car, like the police car or the car by the 8-ball shop. then, go to the bridge and get past the orange cone by slowly going through the right side. Once youre in, get in the middle of the bridge, and get ready to take off! Slam the accelerator and press up on the analog so the nose goes down, once you get to the very edge, where the brigde breaks, press down slightly so the nose goes up, you should make it all the way to the next side. Stauton Island is Awesome!!

Slow and fast gameplay

(During gameplay)
Slow - Press Triangle Up Right Down Square R1 R2
Fast - Press Triangle Up Right Down Square L1 L2

Free BF Injection - To get the BF Injection, the car that Joey Leone is seen working on during mission briefings, go to the telephone in Portland but dont pick up. Just go to the 2 buildings opposite to eachother but in the parking-lot. You can't miss it, it's not a normal looking car. NOTE: You must do this during the night.

Dodo Car - Press Right, R2, Circle, R1, L2, Down, L1, R1 during gameplay. A message will confirm the code entry.

Hint on Flying the Dodo car:  Take the Dodo Car to the very end of the runway (or empty highway, If possible). Turn it around so its facing away from the edge of the road/runway. Hold X to build up momentum, while holding Up. Once you get enough speed, quickly hold Down. Once airborne, use normal controls to level out the car. Note: The dodo car is very difficult to fly (because there are no wings). This code may work with any car.

Indestructible/ Invincible Car - This takes a while, but is definitely worth it. On Portland, after you talk to El Burro of The Diablos, go the the line to start racing, but first you must line up tanks along the whole road. (For tanks push circle 6 times, then R1, L2, L1, Triangle, Circle, Triangle. Then, when one of the carshits it and flips over, you must flip it back over and bring it to your garage. That car will then be invincible.

Extinguish your car (without the fire truck) - Just Simply Press R2(2x), L1, R1, Left, Down, Right, Up, Left, Down, Right, Up while inside your vehicle. If done fast enough your car will be extinguished.
Note: The cheat above is the "Full Health Cheat".

Repair any car for free - Just park the car in the garage, walk out let the door close then walk back up to the garage and there will be a fixed car for FREE.

Get free shot gun - Go to ammo-nation store and after you buy a gun walk up to the clerk and try to point the gun at him the best you can because you can target him, kill him, he shoots back so do it fast and after you kill him walk up to the counter and you will get his shotgun.

Extra Cash - Not a cheat , more of a hint. When in an emergency car ( cop car , ambulance car , fire truck ) or a taxi. Press the right analogue stick ( R3 ) and you can do a sub mission for extra cash

Up to 5 Cars in your Garage

In your garage is Staution Island you can only hold 2 cars...right? Well...there is a way to keep up to 5 cars in there at once!
Heres how you do it:
1.If you have 2 cars already in your garage, go get another one, and bring it to your garage.
2.Park it right in front of the garage with its nose practically on the garage door.(Don't worry this cheat will fix that dent)
3.Then get out of your car and walk to the garage door and when it opens, quickly jump back into your car and gas it!
4. The garage door will try to close on it, but it wont. Park it deep, so the garage door can still be closed.
5.Get out of the garage and presto, 3 cars in there now!
6.If you re-arrange your cars (sideways works well) you can fit 5 cars in your garage and it still closes, letting you have 5 nice cars ready to take out.

Yardie Lobo Shocks - In Staunton Island you can jack the Yardie Lobo, when you speed up and slow down the shocks drop and lower naturally, but if you use the right-analog stick the suspension rises and falls in whatever direction you push it. You can actually roll the car from a stopped position, try it it's fun. Oh yeah, you don't have to save it for your garage to repair your car, just back off so the door closes then get near it to open and your car will be repaired.

Get the tank - All you need is about 15 rockets and 15 grenades and some armor. Get a big truck after you get the stuff mentioned above and go the third level with the airport. Get two stars so the police will follow you to the back of the airport. Go to the Helipad with the police helicopter and get on top of it. Throw the grenades to destroy the police that will come below. Use the rockets on the pesky helicopters after you get full stars start watching the ground for tanks when they come throw a grenade to kill the guys and hurry and jump in. This is the easiest way I could figure out how to do it.

Fast Car - On portland city go to 8 balls BOMB SHOP then go right into the car sales and you will see a banchee car in a glass room smash the window with a car and hey presto you have a nice car

Hidden Packages - When you see the ROCKSTER billboard, there are usually some items nearby. On the 3 islands, hidden packages are usually found near the billboards. For every 10 hidden packages you find, you gain access to a new weapon located at your hideout, free of charge.

Police Bribe - Get 45 kills in vigilante mode to unlock a police bribe that is available in your hideout.

Easy"infinite"Run - To continue at a fast pace without fatigue, just TAP x instead of holding it down. This helps when trying to give your character EXERCISE so that he can run for a long period of time as well.

Bonus Buggy - Successfully complete the Mafia missions to unlock the Buggy. Return to the Portland and go to the Diablo parking lot (where the mission phone is located) between 19:00 to 24:00 to find the same Buggy glimpsed in Joey's garage from the Mafia mission. It will appear in the same location & change color each time.

How To Fly (and turn) The Dodo Plane

Ok, I know that ALOT of people are having a hard time flying the Dodo. So... I decided to write a FAQ to help you all.

NOTE: I just learned how to fly, and trust me,THIS WILL TAKE PRACTICE!

Ok, First off, go to the airport in ShoreSide Vale so you can get the Dodo. When you are there, drive all the way to the beginning of the runway, or just go down by the place where there is another Dodo, and a bunch of helicopters.(NOTE: I get my Dodo usually down in the hanger by the water, but you can get the one near the helipcopters to save time, it doesnt matter.)

Now get on the runway, and make sure you are pointed straight, so when you drive you wont go off the runway,or the black part. Now hold the left analog stick very slightly up. This will cause your place to tilt forwards when you drive, and help pick up speed. The reason why you should barely move it up is because then the plane will take longer to lean all the way down, thus you pick up more speed.

Now while holding up on the left analog stick, start to drive.

Keep going until you see your plane sort of bouncing up and down, and you see sparks.

When you see your plane sort of bouncing and you see sparks, let go of the analog stick gently. This will send your plane shooting into the air, almost vertically, so when you get up, start pressing up, so your will make the plane level. Sort of point it a little downwards so the plane will kind of dive, thus you pick up speed, then you just level the plane by barely moving the analog stick downwards.

Keep pressing up on the analog stick every so often to pick up speed, the plane usually does the rest and makes you gain altitude, so really when you go down and get more speed, the air will sort of pick you up, and make you go higher, but you still need to push the analog stick down a little to help it climb higher, and so that you can fly longer.

NOW YOUR FLYING!

Now turning...

Turning is very hard, and should only really be done when you know where you are flying. To turn, just barely tap the analog stick in the direction you want to turn, but kind of do it diagonally, like right-up, or left-up, NEVER push it left-down or right-down, this will cause your plane to sort of stall. and can be very hard to get it flying again, and you will most likely crash. Never make hard sharp turns, unless you want to crash...

Landing is pretty simple, just make sure your straight, find a long flat place, and press up on the analog stick, this will move you down, and just press Square and R1 when close to the ground, so that you will stop.

Flying Tank - Many people have wanted to fly but you think that you can't because you are on Portland or Staunton Island. Here's a way to Fly. Put in the code for the tank.(Tip:Don't use any fast car they're to fast they keep spinning out)after the tank appears put in the Dodo car code. Now the tank is not fast enough so you will have to turn the cannon around with the right joy-stick. When the cannon is facing behind you, get on a long straight road. Start driving and firing the cannon behind you while you drive. The shots fired will give you the speed you need. You won't need to pull up, the tank will pull up on its own. When you are in the air you need to keep firing to keep up enough speed. Now your fling you can fly as far as you want just get the hang of turning first.

Smaller Moon - The game must be at night for this code to work.1st. Change your gun to a Sniper Riffle if u do not have this gun i suggest that you use the all weapons cheat which is R2, R2, L1, R2, Left, Down, Right, Up, Left, Down, Right, Up. Then Aim at the moon by pressing and holding R1. And Finally fire at the moon by pressing Circle. You can make the moon bigger and smaller as many times as you want.

New Ending - To get the new ending right before you shoot the helicopter and end the game turn on the cheat :All People Hate You. once you do that destroy the helicopter and the ending scene will show a bunch of people running around shooting at you. It is really worth it.

Cops, Army ETC can't get you - On the second island find the casino. when your familiar with the location of the casino just go to the car park through the main entrance when ever you have cops, army, or FBI after you and they won't enter the car park. NOTE (the helicopters can still shoot you)

Get a free infernus (that's a really fast car) - On the third island as you come off of the bridge turn left and go down the road that leads to the airport runway on your right before you get to the barriers there's a car park, go in there and in front of you is a long sports car, just get in. (and your away)

Get a free insane jump stunt bonus - On the third island drive down the road a little bit as you come off of the bridge and on the right side of the road is a brown path in the grass drive as fast as you can down that but be careful it vears off to the left a little bit and also be carful because you may hit the posts on the wooden ramp. (I don't know if you've seen it but I think it looks like the James Bond movie the man with the golden gun when he jumps over the river to get to the baddie)

Get a free fire truck on the third level - On the third level just as you come off of the bridge turn left and go to the little side road towards the airport runway to the left of the car park is a fire truck.

Get a free cop car - Go to the airport and go to the MAIN runway, go to the end of the runway with the helipad and turn right and there's a cop car just sitting there.

Get a second Dodo plane on the third island - Go the Airport's main runway and got the end with the helipad, just in front of the helipad is another Dodo plane.
