Drive around and hit Ballas. When they are dead, pick up their guns then get back in your
car and find more. This will get you a lot of weapons very fast.

Dive underwater, and once your breath is out, you will start losing health. If you want to
stay underwater, keep enabling the "Armor, health, money, and street creds" code when your
health is low. You will be able to remain underwater, and max your Lung Capacity attribute
easily.

This trick requires a controller in port two. To get an easy Hitman rating for either
the 9 mm pistol or shotgun, go to the Los Santos Police Department. Note the two player
icon across the street. Quickly enter the Police Department. Run and ignore any cops
shooting at you and get the armor in the locker room. It is the first room on your right.
There is an available pistol in the room on the right, at the far end of the hall. Proceed
to dispose of the police using your pistol. If you need ammunition, the cops will drop a
gun after you kill them. Your weapon skill will quickly raise as you kill the swarms of
police that come after you. Continue shooting until your armor level becomes low or is
gone. Then, run to the far end of the police station hall, down the stairs, and into the
holding cells. In the middle cell is more armor. Use it and continue your massacre until
your armor is once again depleted. Next, quickly run out of the door and across the street
to the two player icon. Press R3 on controller two to enter two player mode. Simply kill
the second player and your wanted level will be gone and your health will be refilled.
Repeat this to gain Hitman status or simply gain ammunition. Note: Hitman status
with the pistols will allow duel wielding, faster firing, improved accuracy, lock-on range
increased and faster strafing. There is also a shotgun hidden in the police station in the
room on your left as you enter, then to the room at the right at the end of that one. The
shotgun may not respawn as soon as you enter, but in at least 60 seconds one should
appear. You can use this available shotgun to reach Hitman status with. Note:
Hitman status with the shotgun only gives you improved accuracy, move while firing, faster
firing rate and lock-on range increased -- not duel wielding. Duel wielding can only be
achieved with the sawed-off shotgun.

To raise your weapon skills quickly, enter a dance club, such as the "Alhambra" in the
Idlewood area. Begin shooting people with the weapon of your choice. Doing so during the
afternoon or night hours (12:00 to 04:00) greatly increases the amount of people that
respawn in the club. Since so many people spawn, you have a virtually limitless amount of
people to "train" with. Doing so however, raises your wanted level greatly. Enable the
"Lower wanted level" code or know where the police bribes are, as you will need them.

Go to the actual beach part of the Verona Beach area. Start shooting with the desired
gun. The cops will arrive after awhile, but you can make them go away or just kill them
for more. Keep doing this until the desired gun is at Hitman level. It is possible to get
four weapons up to Hitman level in about an hour.

Walk out from CJ's house and make sure there a car in his garage. Use any weapon to
shoot the car in the garage until it catches on fire. Walk away and let the garage close
Then, open it and repeat the steps. You can do this with any weapon to get an easy Hitman
level.

Go into the bar near CJ's house in the Ganton area. Kill everyone there and try to get
a two or three star wanted level. Start killing the police that come through the door.
When no one remains, turn around and look. They should be there.

Leave your car, then immediately re-enter it. Your nitrous will be back at full.

Use the following trick to jump as high as a telephone pole on a bicycle (bunny hop). A
few or more tries may be required to learn the correct timing of the buttons. First, make
sure you have a machine gun. Stand up on your bike by leaning forward on the Left
Analog-stick. Then, as you keep holding Left Analog-stick Up, hold L1 to set up for a
bunny hop. Now, perform this sequence. First, release L1. Immediately afterwards, stop
pressing Left Analog-stick Up. Immediately after that, press Circle to fire your machine
gun. If done correctly, the bike hops many times higher into the air than normal. It is
possible to jump over a two story building from flat ground by doing this.
