Grand Theft Auto III

Puts an extra $250,000 into your cash total.

Fills your body armor bar, giving you a buffer that soaks up damage before your health drops. On the unpatched 1.0 PC release, type TURTOISE instead; patch 1.1 and The Definitive Edition use TORTOISE.

Tops your health back up to the maximum. If you are driving at the time, your vehicle is repaired as well.

Adds every weapon to your inventory, each with ammunition. Entering the code again tops the ammo up further.

Wipes out your wanted level completely, so the police stop pursuing you.

Adds two stars to your wanted level, so more police come after you.

Swaps Claude's character model for the look of one of the city's pedestrians.

Gives every car much more grip and lets it jump. It also disables unique stunt jumps.

Every vehicle around you explodes, the one you are in included, though police helicopters are left alone.

Cars become so light that they lift off at speed and can be steered through the air like a plane.

Car bodies vanish so that only their wheels can be seen. This one is not in The Definitive Edition.

Drops a Rhino tank onto the road nearest to you, which is not always directly in front of you.

Changes the weather to a grey, overcast sky.

Makes the in-game clock run much faster, so days go by quickly. Sources disagree on The Definitive Edition: GamesRadar lists this code as removed, while PC Gamer and the GTA Wiki list it as working.

Speeds up the whole game. Each entry doubles the pace, up to four times normal speed.

Fills the city with thick fog.

Changes the weather to a heavy rainstorm.

Slows the whole game down. Each entry halves the pace, down to a quarter of normal speed.

Changes the weather to clear, sunny skies.

Pedestrians walk around carrying weapons, apart from prostitutes and street criminals. GamesRadar lists it among the cheats that cannot be turned off, so avoid saving afterwards.

Pedestrians start fighting one another all over the city. It cannot be switched off, so avoid saving afterwards.

Pedestrians turn hostile and go for you on sight. It cannot be switched off, so avoid saving afterwards.

Turns on extra gore, so shots can blow off heads and limbs. This one is not in The Definitive Edition. No confirmation message appears, and the GTA Wiki says the classic PC version already shows gore by default unless it is a censored copy or set to a language other than English.
