Cheat Codes
Pause the game and select "Cheats" from the options to enter the Cheats menu.
Enter "TBURGLR" to restore your vehicle to its optimum condition. Enter "AMMO" for maximum ammunition, or "RAINY" to make it instantly rain. "Shazaam" will add lightning. If Tony Montana's outfit is not your tastes, enter "Blue" or "White" for a blue and white costume respectively or "TIGERSH" for a Tiger Stripe outfit with a pair of sunglasses. Enter "OLDFAST" when you need a car. An antique car will suddenly appear.
Unlocking Cheats
Some cheats unlock in-game features. These can be used any time without having to re-enter codes. Enter "F_M_SHA" to unlock the Havana Storehouse, "F_M_SHD" for the Shoreline Storage, "F_M_SHC" for the Leopard Storage and "F_M_SHB" for the Marina Storage. The Plantation will be available if you enter the "A22" cheat. Enter "S07A" to unlock the Freedom Town Redux mission, "S09" for the Nacho Contreras mission, "S10" to unlock the Nacho's Tanker mission, "S13" for Babylon Club Redux mission and "S18" for the mission called The End.
No Heat
Buy an Enforcer or Driver as soon as you can afford one. These are people who will work for you that you can also control. The next time you have heat from police or gangs, or you've lost health, go to your "Map" screen. Choose the "Business" option and select an Enforcer or Driver to change to this character. Swap back to Tony Montana following the same process. You will no longer have heat from the police or gangs and your health will be fully replenished.
Better Weapons
Tony Montana's arsenal of weapons is weaker than some other characters, especially in the earlier stages. The Enforcer has particularly strong weapons, such as a grenade launcher. Select "Business" from the Map screen and pick a character with a weapon you want Tony to have. Place the weapon in the trunk of one of Tony's cars. Change back to Tony and look in the same trunk; the weapon is still there and can now be used by the main character.
