Have you ever wanted to go to a destination, but couldn't find it? Keep on taking the wrong streets? Then you need to know this! This is in the San Andreas Guidbook that comes with the game. It says, "Move the target on the map (start menu) to where you want to go. Press O to drop a destination marker there." Back in game the mini map will have a little mark pointing out where your destination is! Very helpfull! Try it out.

Three different fighting styles
There are three different types of fighting styles that are in the game, to use one, you must first get your muscle strength up to "buff" by working out in the gym. Next go fight the master of the gym that you are in by stepping into the red marker next to him. Once you defeat the master of the gym, he will show you different attacks that you now have, you use these with the triangle button. If you beat the master of the Los Santos gym, you now learn some boxing moves, the San Fierro gym, Martial Arts, and the Las Venturas Gym, Kick Boxing. The moves you currently have depend on the last master that you defeated.

While playing the game, your hood will undergo attacks from other factions. To save yourself some time and end these disaster quickly, simply jack any vehice in which you can access extra missions using R3 ( for example: police vehicles, fire vehicles, taxicabs, ambulance ). Start and end the extra mission (press R3 and exit the vehicle) and your hood will no longer undergo attack.
When you finish some missions, listen to the radio. You'll hear the person talking about the mission just passed.
In one of Zero's mission, where you have to use the machine gun to knock down the RC planes, you can see some action figures of Rockstar characters like Tommy Vercetti, Lance Vance, as well as characters from other games in Rockstar's line-up during Zero's dialogue.
Bullet Proof Cars
During the mission 'High Stakes, Low Rider', keep the competition closely behind you until the pier finish line. Once the race is over the other cars appear behind you. With another car or by just walking, push Ceasar's red car up the pier and over the edge of the sidewalk into your nearby safe house garage to the left. What's the point of all this? Not only is it a pimp red car, it's also bullet proof, which helps alot this early in the game.
Get Into Airport Easily
Go to the airport in Los Santos and find the main gate into the airport when you get to the main gate the man in the little building next to the gate will say you need to go to pilot school well he is wrong get any bicycle and opposite the main entrance to the right inside a gap are some stairs go up the stairs and ride along the roof and bunny hop over the gate from the roof then you will have free access to both planes inside.
Here's a nifty way if you are starting out a new game and want to get to other places. Get a vehicle and locate the train tracks. Drive along the tracks untill you find a parked or moving train (if it is moving, follow it untill it stops at a station). Get in the train (you might encounter a driver if the train was moving, take him out just incase he manages to get you out of the train). Once in drive it in the EASTERN direction. Keep on going, past the woodland areas untill your train slows down automatically. It does this because up ahead there is a block to the other part of the city. Now just go in the opposite direction (I think reverse is easier because it seems it is less prone to derail). Keep on going in that direction (wether it be reverse or not). DO NOT STOP. Your train will speed up quite a bit when you get back in the city, and around the point of a sharp turn, your train will start to rattle, signifying a possible derailment. DO NOT STOP. This is crucial that you do not let up on the throttle. You will then enter a tunnel a fast speeds, and near the end of it, start to automatically slow down; but at the speed you are at now, you will make it through the barrier (Though it will be very close, you will need all the speed you can get). There you go!, just travel along, opening up more of the map. Though be warned, you will have a 4 star rating, and even the police bribe you may get if you drive the train through the city part wont stop it (it will bring it down to 3, then immediatly back up to 4).
