We strongly recommend you don't risk it and don't save once you've used one. With GTA 3 in particular, saving while a cheat is active can corrupt a save file or ruin a main save game by leaving it in a state of chaos.

Don't save whilst the cheat is active.

This is another reason why you should save first, so you can re-load that save game to go back to before you entered the cheat. Re-entering a cheat will often bring up a 'cheat deactivated' message in-game, but in our experience that often leaves the cheat still active, or at least the resulting chaos still well in effect. Always save first so you have a backup just in case. Especially on previous remasters or the PS2 original, using cheats can be a little bit risky, and you'll often struggle to undo the havoc you cause with them turned on, anyway. This is the 'tutorial' and can open up more options when completed, so play until you are 'allowed' to explore the open world, and then start entering cheats.

If cheats don't work from the start of the game, complete the first mission.

As such, use a separate save file for any cheat-filled sessions.

Using cheats can disable Trophies and Achievements.

However, in our experience the ones which work and which don't can vary - so if one code doesn't work one way, try the 'usual' method for that platform to see if that works instead. This means on PC you can use controller input to activate cheats (useful for the new Big Head Mode in particular!) and on console, use the PC keyboard inputs to activate cheats.

Controller and keyboard inputs (mostly) work on all platforms in the Definitive Edition.

Here's the cheat in action via Dan Allen Gaming on YouTube: There is seemingly no PC-specific way to input this cheat by using the keyboard. One is Big Head Mode, which is performed by entering the Konami code (Up, Up, Down, Down, Left, Right, Left, Right) then the right-most face button, then the down-most face button (so on PlayStation, would be Circle then X).

There are new cheat codes in the Definitive Edition.

Rockstar has confirmed it has removed some cheats for technical reasons, and we have verified which have worked for us on this page - and have kept the ones which have worked in previous re-releases below if you are playing those.

Several cheat codes in the 2021 Definitive Edition have been disabled.

While entering cheats in GTA 3 is pretty simple, there are always a few things to bear in mind when you're planning on using them in-game - especially if you are playing the Definitive Edition.
