This tip have helped me in all the GTA games i remember having played: If you back & turn when you need to get away
from a place while driving, you can confuse the police cars, (if its the police who are after you) and you can drive away.
(it also make police men trying to pull you out trip)
If you brake & turn you can make a sharper turn. (sometimes make you spin, if you do anything wrong)
In GTA San Andreas your Character CJ changes sex apeal depending on both what clothes you wear & what car you did
just drive.
In GTA San Andreas one of the possible girlfriends dont like strong men.
So even thoug CJ's brother Sweet promts you to put on some muscles its better to ignore it, till you are done dating
her.
(the girlfriend im talking about is the one named Helena who gives you free weapons if you date her, own a Bandito, and
if you date her to perfection gives you coverall outfit.)
In GTA San Andreas there is 2 vehicles who can pull other vehicles, the Tow Truck and the Tractor.
In GTA3, GTA Vice City, and GTA San Andreas you gain benefits from doing Paramedic, Vigilante, Firefighter, and Taxi
missions.
When you complete an overall of 100 Taxi missions, you get the violent looking Borgnine Taxi in GTA3, all Taxis get hydraulics
in Vice City, & all Taxis get nitro in San Andreas.
Firefighting can gain you the Flamethrower weapon in GTA3, im not sure what you gain in Vice City, and in San Andreas
you get fireproof.(wich is VERY useful in the last mission.)
Paramedic missions gain you drug pills at your hideouts in GTA3, im not sure what you get in Vice City, in San Andreas
you get able to have more health.
Vigilante missions make police stars apear at your hideouts in GTA3, and give you 150% maximum armor in both Vice City
& San Andreas.
In Vice City if you do Pizza missions you get 150% maximum health, as you do if you complete high enough level Paramedic
mission in GTA San Andreas.
