The range of cheats lets you control the weather, NPCs, and, of course, your own character. Some of them even let you cheese the game to get more difficult-to-acquire achievements.
All GTA 3 cheats
As with the Vice City and San Andreas cheats, you’ll want to be a bit careful in how you handle these, assuming Rockstar hasn’t changed the games’ foundations. Entering a cheat in the original GTA 3 and its ports carried a risk of corrupting your save data, and there’s usually no way to undo the cheat. That may be fixed in the remasters, but it’s worth keeping a separate save file you can reload just in case things go wrong. These are all the inputs you can use to manipulate the game.
You’ll need more than a set of GTA 3 cheats or the fastest car to get across the Callahan Bridge early, though it’s worth the effort. Some of the game’s best weapons are found on Staunton Island.
