Gta San Andreas - Invincible Vehicles

This trick requires a cheat.

If you use the Vehicle of Death cheat (makes all vehicles destroy other cars like a tank) it also makes the vehicle you're in invincible, including the Hydra, that means you can run it into a building and it won't take damage, not that you'd want to do that, but it's still a good example.

GTA San Andreas - Paramedic Heals Invible Person

When a Paramedic is healing somebody, if they get hit by a water hose from a firetruck they will get back up and continue to work on the person, but there won't be a person there.

Gta San Andreas - Distorted Graphics while driving fast

If you're driving a very fast vehicle (such as the turismo) and you drive very fast for a long distance, sometimes the graphics will not load well (textures get distorted) or the road won't load, only showing the skybox below.

GTA San Andreas - People Sitting On Air

Find someone sitting on a bench, jump up on it and kick it (not the person) and when the bench goes away the person will be sitting on air.

GTA San Andreas - Invisible vehicles underwater

Somewhere near the bottom left corner of the map, there is a place with a pool of water and some trees(Back O' Beyond). One of the trees is leaning over, you can climb up it and jump in the water, but that's not what this post is about.

Drive a vehicle of some kind into the water, and then get out and look, you can't see the vehicle from the surface, only when you go underwater. This works with anything, even a hydra.

GTA San Andreas - Falling with Health Cheat

If you fall off of a high cliff or building, (one that would kill you) and do the health cheat right as you hit the ground, usually your timing will be bad and you will just die, but three things can happen other than that:

1. you will die, but your health will be filled

2. you won't die on impact with the ground, but it will make another crunching sound a few seconds later and you will die.

3. You won't die. (requires perfect timing or a lot of luck)

GTA San Andreas - Impact with Cars

If you run towards a car and jump right as it hits you, one of several things will happen. Either you will fly higher into the air, jump away from the car, or the car will move upwards.

GTA San Andreas - Hit people with guns

This glitch is quite useless to be honest, but it's kind of neat:

To do this you will need at least a melee weapon (like a baseball bat) and a gun.
Switch to the bat or whatever your using, swing it, then quickly switch to the gun or other weapon. If done correctly you will swing the other weapon like the melee weapon.

GTA San andreas - Flying in Circles

To do this trick, first go to the crane(that you use for exporting and importing vehicles) and attatch it to your car ( any car should do i think )

Then do the flying car cheat (Up, Down, L1, R1, L1, Right, Left, L1, Left)

Now try to drive as fast as you can away from the crane, if done correctly your car will go a little ways into the air, and then you should be able to start flying around in circles (it could take a little bit of adjusting to the crane so that you won't hit anything)

GTA San Andreas - Get into locked cars

To get into locked cars, (such as the one outside of your girlfriends houses before you unlock them) simple push them (or pull them with a tow truck) to a house that has a garage let the door close with the car in it and go back in and you should be able to get into the car.

Gta San Andreas flying under the world

To do this trick you will need to know how to do the "get through solid objects" trick.

In Los santos (where there is a train tunnel heading towards Red County) walk up to stairs at the tunnel and you should see a building and some hills or mountains.

Now do the hydra trick into either the building or the mountains here. you should now be under the mountains, if so i suggest the jetpack cheat
( Left, Right, L1, L2, R1, R2, Up, Down, Left, Right(x2))

Now you can follow the path and fly under buildings, mountains roads and all other kinds of places.
note that it is not very easy to get back to land

Fall several thousand feet into water on the Liberty City Mission on GTA San andreas

this trick will let you partially explore Liberty City until you fall into oblivion

On the mission where you go to liberty city, continue the level until you reach the outside area where the main guy you've gotta kill is kill his friends but leave him alive (so you don't pass the mission)

Now do the High Jumps Cheat( Up, Up, Triangle, Triangle, Up, Up, Left, Right, Square, R2, R2)

now there are probably a number of places to do this so just jump around until you find a ledge or building you can climb over, now walk around at your own risk.
Some buildings and things are solid but the streets are not so if you walk onto them you will fall what seems like several hundred feet into a pool of water
(note that there isn't any escape besides loading or using the suicide cheats)

GTA San Andreas Get through solid objects

this is a neat little glitch that can get you through buildings, mountains, etc

so here is what you need to do:

first of all this requires a cheat code(spawn hydra)
if my memory is correct for ps2 you press:

Triangle, Triangle, Square, Circle, x ,L1, L1, down, up

Now this next part is a little more challenging you must get at the right angle at the building
so that when you spawn the hydra it will be partially inside of the building with the cockpit side out, and far enough that you can get in (this may take practice) if you've done this right, get into the hydra and quickly get back out, you should be inside of the building, or mountain
