GTA: San Andreas Secrets
Rack up money at safe house
If you leave your PS2 running in order to build up money at your safe house you will eventually lose all your life from hunger and end up in the hospital. However, if you go into CJ's house and leave him playing the video game system in the living room, money will still build up and his health will no longer deplete.
Sex Toy Weapon
In Los Santos, go inside any police station and go into the shower room. Inside you will find a purple sex toy you can use as a very powerful weapon.
Become In debt to the mob
After obtaining a high gambling skill, gamble in Caligua's until you have actually lost money. (Your money will turn red). After a while you will receive a call from a mobster at Caligua's, who informs you that you owe him money. Later again, he will call you and tell you that some of his "associates" are coming to talk about the money. You will then be hunted down by the mafia, and they will try to kill you.
Infinite Photos
First, save your game (with a camera). Now, press L1 to take pictures of any photos you want (save it in your gallery), until you're done photographing. When you are, reset the console. The photos you have taken will still be in your gallery, only you won't have lost any film!
Fast and Easy way to upgrade weapon skills
Take the gun you want to be upgraded and aim it at a tire of any vechicle. Then just keep firing and your skill builds up quick.
Police Impound Garages
To get the car you were busted in go to the local city police station (LSPD, SFPD, and LVPD) and enter the garage with a police vehicle. Drive down to the very end of the garage to find your car you were busted in.
Win Chiliad Challenge easily
When doing the Chiliad challenge let the other racers finish before you. Then stop before hitting the final marker and get off. Next get out a sniper rifle and snipe all of the competitors. After each snipe you'll notice your position is going up. If you snipe them all you will be in first place.
Use the Vortex as a Submarine
Use the Vortex between El Quebrados and the abandoned airfield to take the small unique jump ramp that's on the back of the small shack it's parked next to. When you land in the water, the unique jump slow-motion cinema should keep going, with the camera fixed in one spot. Drive way out into the reservoir, and towards the dam, to the left of the camera's view. You'll disappear from view, but keep going. Eventually you'll run into the side of the dam and the cinema will end, leaving you under water and able to steer the Vortex like a submarine, without draining lung capacity or anything, as if you weren't underwater at all.
Chilliad Challenge easy win alternative way
Another way to easily complete every race in the Chilliad Challengeis quite simple, throw a grenade at your opponent(s) and they will be eliminated from the race. Normally, using a weapon will get you disqualified, but using a grenade is fine by the games standards, and this method is a lot less cheap than the other one for this challenge, and works just as effectively.
Get No Stars While Blowing Up Vehicles
In a helicopter you won't get any stars if you use the chaingun for blowing up cars instead of the rockets. Even if they're right behind the guy you're shooting. As long as you don't kill any pedestrians or hit a cop car with a stray bullet.
No Timer on Quarry Mission
On the mission where you have to steal dynamite for a Wuzie mission you normally have a timer but if you go to the center of the construction site there is a grey stage with a person on it and the dynamite plunger right in front of him. If you kill him the timer will stop and you will have all of the time you need to complete this mission.
Easy High Score in the Arcade Game "They Crawled From Uranus"
Once the game starts simply hold the joystick in one direction and the aliens' fire will never hit you. If you fire while doing this you can easily rack up points without ever dying.
Free money in Pig Pen without money cheat.
When you enter the Pig Pen, jump onto the stage. When you get on the stage, walk infront of the Stripper. The men will throw 20 Dollars to her. Since you are where the money appears, you collect it. They throw the money in 20 dollars intervals every 10 seconds. Great for begginers since Pig Pen is 1 minute from CJ's house.
Get out of debt trick
To get out of debt, no matter how far you are in, find a Unique Stunt Jump that you haven't been rewarded on yet. Hit the jump and you will be rewarded. However, this causes your money counter to reset to all zeroes.
Free ammo without pay purchase
Enter an ammunation shooting range and then press triangle to leave it. Gives full ammo to whatever gun you had equipped.
Get Twice the Amount of Progress With Girlfriends
You have to have two controllers for this trick. When you go to your girlfriend's house you have a choice of either going on a two player free roam or going on a one player date. However, at the end of the one player date the two player icon (usually located by the door) will linger for a few seconds. You have to quickly go into the icon and activate it before it disappears. After that you can either end the free roam quickly or play around it doesn't matter. If your one player date was good and you gained progress you will gain even more progress from the free roam. However, if you had a bad date you lose more progress by activating it.
Infinite Spray Paint
In the earlier Sweet Mission "Tagging up Turf" you receive an infinite spray paint can. Since there is no timer on this mission, you can go around Los Santos with the FAQ tag map and spray all the tags without refilling the paint. Sweet!
Basketball Cheat
If you have a wanted level and start to play basketball, you cannot be injured in any way.
