Pause the game, choose "CHEATS". and enter one of the following.

You can find these under the "Exotics" menu, and "Investments" option. The purpose of the investments is to provide upgrades to the game or to your player. You will need at least $1.5 million ($40 million for Montana Legal and $20 million for Montana Sports) to purchase most of these investments. The investments will help you level up faster.

If you've got busted and the cops took all ur money, or u spent it all on renovating your mansion, don't worry. First get a weapon, and find a drug dealer on the map (a drug dealer is a white dot on the map) and kill him. Make sure there is no gangs there, or they'll start a gang war!. Take the yeyo and money, get a car and kill another dealer. Take his yeyo and cash and keep doing this. Once you have around 100grams of drugs sell them to a dealer but youll need to get the dealing metre high enough to sell, then kill him and take the stuff back, as well as his stuff. Keep doing this and you'll be rich again in mins!

Some characters like the assassin and enforcer have stronger weapons. For example, play as the enforcer. Call for one of Tony's cars. once it arrives, go to the weapons trunk. Place the grenade launcher in the trunk, tehn switch back to Tony. When you go to the weapons trunk, the grenade launcher will still be there. You can do the same thing with the assassin to get the PSG-1.

Enable the "Bodog Stampede" code. Then, go after the gangs with it. The gun will have unlimited ammunition and enough armor to take them all out. If you run low on your vehicle's health, enable the "Repair vehicle" code. However, you must move your Hummer once in awhile or they will pull you out. This also is very useful when taking over the storehouses because of all the armor it has.

Go to the Babylon Club. Go to the main area and hold L1. Tony will start to dance. You can also make Tony spin by pressing R1.

Press L2 and go to your "Empire". Then go to the "Buisness" option. Select "Felix Lead" and complete the missions. Once completing 2-3 missions a "small supplier" mission will pop up. Begin the mission and drive to the X mark.

Note - makesure you have low gang heat and that you have lost your tail if you had one. Once at the X spot you will see a Drug Lord with a "g" above his head and he willl have bodyguards surrounding him. Kill the Drug Lord and quickly grab the drugs that he drops which is usualy 200g of coke. Keep doing this until you have 5000g then sell it to your "fronts" and you will make heaps of cash. You can also sell it back to small time drug dealers then kill them.

Note - killing drug lords creates huge gang heat,keep using the gang heat cheat to decrease it. THIS IS THE BEST WAY TO GET FAST COKE AND MONEY !

R U like tired of swimmin and a shark comes out of the water and eats ya? Wanna see the shark eat someone else? Alright so I'm walking down this peer (on the beach on the 2nd Iland) I look and see this other walk way that goes out even more( after hiting it with a boat soo meny times) I run down it (it won't work if u drive down it) I get almost to the end, and Tony stops movin. Then the screen goes off to the side, where a girl is swimmin up to shore and a shark comes up behind her, and eats her. ok, now go die and come back, it'll do it agian.

This is not a joke!!! enter the cheat to commit suicide(or kill yourself some other way. Then travel to south beach in any car and go west of south beach and towards the end of the beach there will be a very large stone dock, drive your vehicle down the dock at full speed until you hit the water after that there will be a short clip of a girl saying threatening words but being attacked by a shark(not you)

In all missions there is a point where your swamped with enemies get in a car run them over never use rage because at the end you will need it. When running them over never jumped out stop them get out or while standing up you lose about 50% of your health.

Go to pedros pawn shop go south and you will see a side entry the go down it in till you get to the end the do the keep doin the balls cheat and you can give balls into the spearm bank. note:it gives you 25'000 for 1000 balls.

You will need the health cheat and the cheat to repair your car. Drive to your house if your car is on fire repair your car with the cheat. run into your house and stand at your door but you still have to stay inside your house and there should be a helicopter flying in front of your house get your gun out and lock on to the helicopter and shoot at it until it explodes and it should come ip on the screen incedent or something like that. and all the police should go away and all your cop heat will go down.

This may should weird, but its true. Go down to any oceans and swim straight. Eventually, the screen will pause and then show a little preview or Tony getting eaten by a shark. After that, you end up to where you last saved. This is pretty cool so i suggest you try it.
